Analysis of the prognostic effect of concomitant use of left ventricular assist devices (LVADs) and implantable -cardioverter defibrillators (ICDs) is lacking. The aim of this study is to define the survival effects of ICD therapy in ambulatory patients with LVAD. Patients with continuous-flow (cf) LVAD in a single tertiary center from December 2010 to May 2016 were retrospectively analyzed. Over a 6-year period, 257 patients had cf-LVAD implantation, 227 of them survived to discharge after the first month of LVAD implantation and were included in the study. The median follow-up time was 14 months, and 104 (45.8%) patients had ICD. One hundred and thirty-two (58.1%) patients were still under LVAD support at the end of the study period. Forty (17.6%) patients had heart transplantation, and 55 (24.2%) died. There was no significant difference between groups with ICD and without ICD for baseline characteristics except for higher pulmonary pressures and amiodarone use in the ICD group. Survival analysis showed significant survival benefit of ICD therapy (P =.02). After multivariate analyses including age, sex, left ventricular ejection fraction, and β-blocker usage, the benefit of ICD continued (hazard ratio: 0.54; 95% confidence interval, 0.303-0.975; P =.041). Ventricular arrhythmias (VAs) do not cause acute hemodynamic deterioration in patients with LVAD. However, VAs might be associated with poor prognosis. The present study showed that ICD therapy may improve survival among ambulatory patients with cf-LVAD–supported heart failure. • Left ventricular assist devices (LVADs) are an increasingly used technology for the management of the patients with advanced heart failure. • There are conflicting results about survival benefits of implantable-cardioverter defibrillator (ICD) therapy in patients with LVAD. • Ambulatory patients with LVAD after the first month of implantation are evaluated in the present study. • The presence of an ICD was associated with improved survival. • Right ventricular failure, pump thrombosis, and ischemic stroke were more common in patients with LVAD but without ICD.

Background Right ventricular ( RV) function has great impact on the survival of heart transplantation recipients; therefore, careful evaluation is of high clinical importance. However, there is no standard conventional echocardiographic parameter to assess RV systolic function. Herein, we evaluated the correlation between echocardiographic parameters of RV systolic function and ejection fraction assessed by cardiac magnetic resonance imaging ( MRI RVEF) in heart transplantation recipients. Method and Results Forty-three patients with at least 6-month heart transplantation history were included in this study. Each patient had conventional echocardiography and cardiac MRI evaluation, followed by endomyocardial biopsy and right heart catheterization, which were performed in six hours. Echocardiographic parameters of RV systolic function, RV fractional area change ( RV FAC), tricuspid annular plane systolic excursion ( TAPSE), RV myocardial performance index, and RV global longitudinal strain, were compared with MRI RVEF ( P values were <0.001, <0.3, <0.9, and <0.4, respectively). RV FAC was the only parameter to strongly correlate with MRI RVEF ( r=0.747, P<0.001); and RV FAC 48.5% value had 90.5% sensitivity and 90.5% specificity to predict the pathologic reference value of MRI RVEF ≤50% ( AUC:0.96; 95% CI, 0.908-1.013). Conclusion To our knowledge, this is the first prospective study to evaluate the correlation between the echocardiographic parameters for RV systolic function and MRI RVEF in heart transplantation recipients. RV FAC is the only parameter to correlate well with MRI RVEF, and its routine use in the follow-up of heart transplantation recipients should be considered. [ABSTRACT FROM AUTHOR]

Objective: Allograft rejection is still an important cause of morbidity and mortality after heart transplantation (HTx). Many techniques in cardiac magnetic resonance imaging (CMR) were investigated to diagnose acute cellular rejection (ACR). However, there is not enough information about late gadolinium enhancement (LGE) in the myocardium and ACR. Methods: We prospectively analyzed our consecutive 41 heart transplant recipients who were admitted for routine endomyocardial biopsies. CMR was performed maximum 6 h before the scheduled endomyocardial biopsy. Correlation between LGE in the myocardium and ACR was investigated. Results: Twenty-seven patients showed no rejection, and nine of them had LGE in the myocardium. Fourteen patients had LGE in the left ventricle (LV), and two patients had LGE also in the right ventricle (RV). There was no correlation between LGE and ACR (p=0.879). There was no difference in the left ventricular ejection fraction (LVEF), right ventricular fractional area change (RVFAC), and cardiac ischemic time between the groups (p=0.825, p=0.370, and p=0.419, respectively). LGE in the myocardium could be due to previous rejection episodes; therefore, all patients were retrospectively searched for previous rejection grades and number of episodes. Thirty-eight of the 41 patients had a history of one ACR episode, but none of them had a statistically significant correlation with LGE (for grade 1R, p=0.964 and grade 3R, p=1) There was also no correlation between number of rejection episodes history and LGE. Conclusion: LGE is not suitable to detect ACR in heart transplant patients. LGE and the history of ACR have no correlation. [ABSTRACT FROM AUTHOR]

HEART assist devices , *HEART failure patients , *HEART failure , *ARTIFICIAL blood circulation , *HEART transplantation , *CARDIO-renal syndrome - Abstract
This clinical consensus statement reviews the use of inotropic support in patients with advanced heart failure. The current guidelines only support use of inotropes in the setting of acute decompensated heart failure with evidence of organ malperfusion or shock. However, inotropic support may be reasonable in other patients with advanced heart failure without acute severe decompensation. The clinical evidence supporting use of inotropes in these situations is reviewed. Particularly, patients with persistent congestion, systemic hypoperfusion, or advanced heart failure with need for palliation, and specific situations relevant to implantation of left ventricular assist devices or heart transplantation are discussed. Traditional and novel drugs with inotropic effects are discussed and use of guideline‐directed therapy during inotropic support is reviewed. Finally, home inotropic therapy is described, and palliative care and end‐of‐life aspects are reviewed in relation to management of ongoing inotropic support (including guidance for maintenance and weaning of chronic inotropic therapy support).

Pulmonary arterial hypertension (PAH) is an uncommon disorder that may be hereditable, idiopathic or associated with conditions like drug exposure, connective tissue disease, HIV infection or congenital heart disease. Familial disease are usually due to mutations in the bone morphogenic protein receptor type 2 (BMPR2), activin-like kinase-type 1 (ALK1) and endoglin (ENG). Functional and structural changes in the pulmonary vasculature lead to increased pulmonary vascular resistance. Vascular remodeling involves endothelial dysfunction, activation of fibroblasts and smooth muscle cells and recruitment of circulating progenitor cells. Vasoconstriction has also been shown to affect the remodeling process. Genetics, cellular and molecular basis of PAH are discussed in the paper. [ABSTRACT FROM AUTHOR]

From January 2001 through June 2002,128 consecutive patients undergoing lung resection for various diseases were evaluated preoperatively by a cardiologist at our institution in order to predict postoperative cardiac complications in pulmonary surgery. Our assessment algorithm consisted of the following: Smoking, hypertension, hyperlipidemia, advanced age, diabetes mellitus, and history of cardiac disease or angina pectoris were considered as risk factors. A stress test was performed when at least 2 of the first 3 risk factors or at least 1 of the last 3 risk factors was present. Coronary angiography was performed in the case of a positive stress test. Patients were classified as low-risk when there was no need for a stress test. Patients were considered as intermediate-risk when a stress test revealed no ischemia or if there was a history of congestive heart failure or valvular disease. Patients in whom coronary artery disease was detected on angiography were classified as high-risk. Ninety-five of our patients were in the low-risk group, and 29 were in the intermediate-risk group. After lung resection,cardiac complications developed in 4 patients in the low-risk group (atrial fibrillation) and in 8 patients in the intermediate-risk group (5 atrial fibrillation and 3 paroxysmal atrial tachycardia). The overall cardiac complication rate was 9.7%. No death occurred due to cardiac events. The difference in the incidence of arrhythmias between the low-and the intermediate-risk groups was significant (P <0.05). We present this simple algorithm for preoperative cardiac evaluation in patients scheduled to undergo lung resection, and we suggest that it may be possible to predict post-operative cardiac complications with this method.

HYPERTENSION , *IMPOTENCE , *ATENOLOL , *BLOOD circulation disorders , *THERAPEUTICS , *NITRIC oxide - Abstract
Background and objective: Erectile dysfunction, which is common in men with hypertension, has been reported as a common adverse effect of many antihypertensive drug classes, including β-blockers and diuretics. Atenolol and nebivolol are both β1-selective blockers, but nebivolol is a new-generation compound with nitric oxide-mediated vasodilating activity. The aim of the study was to compare the effects of nebivolol and atenolol ± chlorthalidone on the sexual function of hypertensive men. Methods: A total of 131 male patients (mean age 47.3 ± 4.6 years) with newly diagnosed hypertension were included in the study. All the patients were married and had not previously experienced any erectile dysfunction. After a 4-week placebo run-in period, patients were randomised to receive 12 weeks’ therapy with nebivolol 5 mg/day (n = 43), atenolol 50 mg/day (n = 44), or atenolol 50 mg/day + chlorthalidone 12.5 mg/day (n = 44), according to a double-blind design. After 4 weeks of treatment, drug dosage could be doubled in patients not responding to therapy. Erectile function (instances of successful intercourse/month) was assessed by means of a questionnaire at the end of the placebo run-in period (baseline) and at the end of double-blind treatment. Blood pressure was also assessed at these times. Results: At the end of the 12-week, double-blind treatment period, the mean number of episodes of satisfactory sexual intercourse per month was significantly decreased from baseline in the groups receiving atenolol (from 7.0 to 3.7; p < 0.01) and atenolol + chlorthalidone (from 6.4 to 2.8; p < 0.01). In contrast, the mean number of episodes of satisfactory sexual intercourse per month remained constant in the group of patients receiving nebivolol (6.4 during the baseline assessment and 6.0 during the last month of treatment). Blood pressure and heart rate were significantly decreased from baseline in all treatment groups. Conclusion: Increased release of nitric oxide associated with nebivolol may counteract the detrimental effect of β-blockade on penile erection, thereby allowing maintenance of sexual activity in previously untreated hypertensive men compared with a significant decrease observed in the sexual activity of men receiving atenolol-based treatment.

Background: In the past decade, many studies have indicated that the combination of low doses of different classes of antihypertensive agents may be more efficacious than monotherapy while minimizing the likelihood of dose-dependent adverse effects (AEs).Objective: The aim of this study was to determine whether combination therapy with lower doses of candesartan and a calcium antagonist, felodipine, would be more effective and tolerable in controlling mild to moderate hypertension compared with either drug used alone.Methods: In this 18-week, single-center, double-blind, crossover study, patients with mild to moderate essential hypertension were randomized to 1 of 2 treatment groups after a 2-week placebo washout period. Patients in group 1 received candesartan 16 mg once daily and patients in group 2 received felodipine 5 mg once daily, for 6 weeks. All patients then received half-dose combination therapy (candesartan 8 mg plus felodipine 2.5 mg, once daily) for 6 weeks. Finally, patients received 6 weeks of monotherapy with the alternate medication (group 1 received felodipine 5 mg once daily and group 2 received candesartan 16 mg once daily).Results: Thirty patients (18 men, 12 women; mean [SD] age, 54.0 [4.9] years; range, 39–62 years) were included in the study. During both monotherapy periods, candesartan and felodipine significantly reduced blood pressure (BP) (both P<0.001). BP further decreased with combination therapy (P<0.001 in both groups). Overall, 90.0% (27/30) of the patients achieved the target BP at the end of combination therapy. The incidence of AEs was similar with combination therapy compared with either monotherapy.Conclusions: In this study population, candesartan and felodipine had additive effects when used in combination, even at low doses, in the treatment of hypertension. Therefore, the combination of candesartan and felodipine is an effective alternative to that of candesartan and hydrochlorothiazide. [Copyright &y& Elsevier]

HYPERTENSION , *THERAPEUTICS , *ARRHYTHMIA - Abstract
Background: The high incidence of ventricular arrhythmias in patients with hypertension and left ventricular hypertrophy (LVH) is well documented. However, few studies have been conducted on the prevalence of ventricular arrhythmias in patients with isolated systolic hypertension without LVH.Objectives: The objectives of this study were to (1) determine the prevalence of ventricular arrhythmias in patients with systolic hypertension without LVH and (2) estimate the effect of a perindopril/indapamide combination, which does not have an antiarrhythmic effect, on the incidence of ventricular arrhythmias.Methods: Patients with newly diagnosed isolated systolic hypertension (systolic blood pressure [SBP] >160 mm Hg) and a control group of normotensive patients were enrolled. During the 2-week washout period, patients underwent physical examination (including blood pressure measurements), ambulatory electrocardiography monitoring, echocardiography, and laboratory urine and blood tests. Absence of LVH was confirmed by echocardiographic examination. The group of hypertensive patients received 1 tablet of 2 mg perindopril/0.625 mg indapamide per day for a total of 4 weeks. Physical examinations and ambulatory electrocardiographic monitoring were repeated after treatment.Results: A total of 60 hypertensive (mean age, 63.1 years; mean SBP, 176.8 ± 3.1 mm Hg; mean diastolic blood pressure, 82.6 ± 2.9 mm Hg) and 60 normotensive patients were enrolled. Ambulatory electrocardiographic monitoring indicated that 18 of the 60 hypertensive patients (30%) had ventricular arrhythmias: 17 had ventricular premature contractions (>100/24 h) and 1 had ventricular tachycardia plus ventricular premature contractions. In the control group, 7 of 60 subjects (11.7%) had ventricular premature contractions. The difference between the 2 groups in incidence of ventricular arrhythmias was significant (P < 0.01). After treatment, mean SBP decreased to 136.1 ± 3.2 mm Hg, and ventricular premature contractions were found in 9 of 60 hypertensive patients (15%) (P < 0.02 vs pretreatment).Conclusions: The results of this study suggest that in patients with isolated systolic hypertension without LVH, (1) the prevalence of ventricular arrhythmia is higher than in normotensive patients and (2) treatment with perindopril/indapamide decreases the incidence of ventricular arrhythmias.

We sought to investigate the impact of heart failure on anti-spike antibody positivity following SARS-CoV-2 vaccination. Our study included 103 heart failure (HF) patients, including those with and without left ventricular assist devices (LVAD) selected from our institutional transplant waiting list as well as 104 non-heart failure (NHF) patients who underwent open heart surgery at our institution from 2021 to 2022. All the patients received either heterologous or homologous doses of BNT162b2 and CoronaVac. The median age of the HF group was 56.0 (interquartile range (IQR): 48.0–62.5) and the NHF group was 63.0 (IQR: 56.0–70.2) years, and the majority were males in both groups (n = 78; 75.7% and n = 80; 76.9%, respectively). The majority of the patients in both the HF and NHF groups received heterologous vaccinations (n = 43; 41.7% and n = 52; 50.3%, respectively; p = 0.002). There was no difference in the anti-spike antibody positivity between the patients with and without heart failure (p = 0.725). Vaccination with BNT162b2 led to significantly higher antibody levels compared to CoronaVac alone (OR: 11.0; 95% CI: 3.8–31.5). With each passing day after the last vaccine dose, there was a significant decrease in anti-spike antibody positivity, with an OR of 0.9 (95% CI: 0.9–0.9). Furthermore, hyperlipidemia was associated with increased antibody positivity (p = 0.004). [ABSTRACT FROM AUTHOR]

PULMONARY hypertension , *CARDIAC output , *HYPERTENSION , *CARDIOGRAPHY , *PEARSON correlation (Statistics) - Abstract
Background: Pulmonary hypertension guidelines recommend invasive right heart catheterization for diagnosis and clinical follow-up. Our aim was to compare non-invasive impedance cardiography with invasive techniques for cardiac index measurements and mortality prediction in patients with pulmonary hypertension. Methods: Between 2008 and 2018, 284 right heart catheterizations were performed for the diagnosis of pulmonary hypertension in 215 patients with mean pulmonary artery pressure >25 mm Hg, and at least 2 methods used for cardiac output measurement were included in the study retrospectively. Patients were evaluated with Pearson’s correlation in 3 groups: estimated Fick (eFick) method and thermodilution (group 1), eFick method and impedance cardiography (group 2), and thermodilution and impedance cardiography (group 3). We also compared the predictive power of cardiac index measured by different methods for 1-year overall mortality and hospitalizations. Results: There were strong and moderate positive correlations in groups 1 and 3, respectively (r=0.634, P < .001, r=0.534, P=.001), and the weakest correlation was in group 2 (r=0.390, P=.001). The mean difference (bias) between eFick method versus impedance cardiography, impedance cardiography vs. thermodilution, and eFick method vs. thermodilution was 0.6 mL/min, 0.47 mL/min, and −0.2 mL/min respectively, but limits of agreement were wide. In both groups, cardiac index <2.5 L/min/m² as measured by thermodilution significantly predicted 1-year mortality. Also, impedance cardiography was better than eFick method in predicting mortality (P=.02). Conclusions: Our single-center real-life data showed that for cardiac output and cardiac index measurements, impedance cardiography provides a moderate correlation with thermodilution and is fair with eFick method methods. Moreover, thermodilution appeared superior to both eFick method and impedance cardiography, while impedance cardiography was even better than eFick method in predicting 1-year adverse events, including total mortality and hospitalization, in patients with pulmonary hypertension.

Objective: The purpose of this study is to compare the analysis of right ventricular (RV) free wall strain via 2D speckle tracking echocardiography with conventional echocardiography and clinical parameters in patients with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD) receiving specific treatment. This study also aims to describe the differences between patients with repaired and unrepaired defects. Methods: This prospective study included 44 adult patients with PAH-CHD who were receiving PAH-specific treatment in a single center. This study excluded patients with complex congenital heart disease. The authors studied the conventional echocardiographic parameters, such as RV fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE), right atrial (RA) area, Tricuspid S', and hemodynamic parameters, such as functional class, 6-minute walking distance (6MWD), and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels. Results: The mean age of participants was 33.8±11.6 years, and 65.9% of participants were female. The mean RV free wall strain was -14.8±4.7%. Majority of the patients belonged to WHO functional class 2 (61.4%) with a mean NT-proBNP level of 619.2±778.4 and mean 6MWD of 400.2±86.9 meters. During the follow-up of 30.8±9.0 months, 6 patients (13.6%) developed clinical right heart failure, whereas 9 (20.5%) of them died. There was a positive and significant correlation between RV free wall strain and WHO functional class (r=0.320, p=0.03), whereas there was a negative correlation between RV free wall strain and FAC (r=-0.392, p=0.01), TAPSE (r=-0.577, p=0.0001), and Tricuspid S' (r=-0.489, p=0.001). There was no significant correlation of RV free wall strain with either RA area or 6MWD. Patients with repaired congenital heart defects had worse RV functional parameters and RV free wall strain than patients with unrepaired defects. Conclusion: The assessment of RV free wall strain via 2D speckle tracking echocardiography is a feasible method and correlates well with conventional echocardiography and clinical parameters in patients with PAH-CHD receiving specific treatment.

- Abstract
Background: Risk assessment is recommended for patients with congenital heart disease-associated pulmonary arterial hypertension. This study aims to compare an abbreviated version of the risk assessment strategy, noninvasive French model, and an abridged version of the Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management 2.0 risk score calculator, Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2. Methods: We enrolled a mixed prevalent and incident cohort of patients with congenital heart disease-associated pulmonary arterial hypertension (n = 126). Noninvasive French model comprising World Health Organization functional class, 6-minute walk distance, and N-terminal pro-hormone of brain natriuretic peptide or brain natriuretic peptide was used. Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 includes functional class, systolic blood pressure, heart rate, 6-minute walk distance, brain natriuretic peptide/N-terminal pro-hormone of brain natriuretic peptide, and estimated glomerular filtration rate. Results: The mean age was 32.17 ± 16.3 years. The mean follow-up was 99.41 ± 58.2 months. Thirty-two patients died during follow-up period. Most patients were Eisenmenger syndrome (31%) and simple defects (29.4%). Most patients received monotherapy (76.2%). Most patients were World Health Organization functional class I-II (66.6%). Both models effectively identified risk in our cohort (P = .0001). Patients achieving 2 or 3 noninvasive low-risk criteria or low-risk category by Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 at follow-up had a significantly reduced risk of death. Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 approximates noninvasive French model at discriminating among patients based on c-index. Age, high risk by Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2, and the presence of 2 or 3 low-risk criteria by noninvasive French model emerged as an independent predictors of mortality (multivariate hazard ratio: 1.031, 95% CI: 1.005-1.058, P = .02; hazard ratio: 4.258, CI: 1.143-15.860, P = .031; hazard ratio: 0.095, CI: 0.013-0.672, P = .018, respectively). Conclusions: Both abbreviated risk assessment tools may provide a simplified and robust method of risk assessment for congenital heart disease-associated pulmonary arterial hypertension. Patients not achieving low risk at follow-up may benefit from aggressive use of available therapies. [ABSTRACT FROM AUTHOR]

Aspergillus aortitis following cardiac surgery has an important role among the cardiac infections as almost all affected cases result in death. Survival of the patient with Aspergillus aortitis is dependent on early initiation of aggressive medical and surgical treatment. Transesophageal echocardiography proved very useful in the diagnosis of this uncommon case of aortitis. In this paper, we present a patient with aortitis caused by Aspergillus niger that hasn't been reported previously diagnosed by transesophageal echocardiography following cardiac surgery.

- Abstract
Natriuretic peptides are widely used in all types of heart failure. Previously, we defined heart failure with non-reduced ejection fraction as patients with heart failure symptoms and/or signs and who have left ventricular ejection fraction > 40%.1 For the diagnosis of heart failure with preserved ejection fraction, the presence of raised natriuretic peptides is one of the major components of the diagnosis, and raised natriuretic peptides make the diagnosis more likely in patients with heart failure with mildly reduced ejection fraction.2 The majority of the existing studies have described the utility of natriuretic peptides in patients with heart failure with reduced ejection fraction, but there is not enough data on natriuretic peptides in heart failure patients with heart failure with non-reduced ejection fraction. Despite the insufficient information regarding the usage of natriuretic peptides in heart failure with non-reduced ejection fraction, it is obvious that there is an unmet need to guide how to use natriuretic peptides in these patients. The main goal of this article is to discuss the role of natriuretic peptides in diagnosis, prognosis, and guidance of heart failure treatment in patients with heart failure with non-reduced ejection fraction. The present review discusses the role of natriuretic peptides in heart failure with non-reduced ejection fraction focusing on: the characteristics of natriuretic peptides, primary prevention of heart failure, diagnosis of heart failure with non-reduced ejection fraction in different patient characteristics and co-morbidities, prognosis of heart failure, monitoring of heart failure treatment and, how to use in worsening heart failure.

PULMONARY hypertension , *RIGHT ventricular hypertrophy , *MICRORNA , *PULMONARY arterial hypertension , *GENE expression - Abstract
Background/aim: Pulmonary arterial hypertension (PAH) is characterized by maladaptation of pulmonary vasculature which is leading to right ventricular hypertrophy and heart failure. miRNAs play a crucial role in the regulation of many diseases such as viral infection, cancer, cardiovascular diseases, and pulmonary hypertension (PH). In this study, we aimed to investigate the expression pattern of eight human plasma miRNAs (hsa-miR-21-3p, hsa-miR-143- 3p, hsa-miR-138-5p, hsa-miR-145-3p, hsa-miR-190a, hsa-miR-204-3p, hsamiR-206, hsa-miR-210-3p) in mild-to-severe PH patients and healthy controls. Materials and methods: miRNAs were extracted from the peripheral plasma of the PH patients (n: 44) and healthy individuals (n: 30) by using the miRNA Isolation Kit. cDNA was synthesized using All in-One First strand cDNA Synthesis Kit. Expression of the human plasma hsa-miR- 21-3p, hsa-miR-143-3p, hsa-miR-138-5p, hsa-miR-145-3p, hsa-miR-190a, hsa-miR-204- 3p, hsa-miR-206, hsa-miR210-3p, and miRNAs were analyzed by qRT-PCR. Results: According to our results, in PH patients hsa-miR-21-3p and hsa-miR-143-3p expression levels were decreased by 4.7 and 2.3 times, respectively. No significant changes were detected in hsa-miR-138-5p, hsa-miR-145-3p, hsa-miR-190a, hsa-miR-204-3p, hsamiR-206, and hsa-miR-210-3p expression levels between PH and control groups. In addition, considering the severity of the disease, it was observed that the decrease in miR-138, miR-143, miR-145, miR-190, mir-204, mir-206 and miR-208 expressions was significant in patients with severe PH. Conclusion: In the early diagnosis of PAH, hsa-miR-21-3p and especially hsa-miR-143-3p in peripheral plasma can be considered as potential biomarkers. [ABSTRACT FROM AUTHOR]

Objective: Peripartum cardiomyopathy (PPCM) diagnosis made by excluding identifiable causes of heart failure (HF) and occurs end of the pregnancy or during the postpartum period of five months. It presents a clinical HF spectrum with left ventricular systolic dysfunction. Background: The purpose of this study is to retrospectively evaluate the clinical characteristics, cardiac magnetic resonance (CMR) imaging features, and end‐points consisting of left ventricle recovery, left ventricular assist device implantation, heart transplantation, and all‐cause mortality. Method: Outpatient HF records between 2008 to 2021 were screened. Thirty‐seven patients were defined as PPCM. Twenty‐five patients had CMR evaluation at the time of diagnosis, and six patients were re‐evaluated with CMR. Results: The mean age was 30.5 ± 5.6 years, and the mean LVEF was 28.2% ± 6.7%. In 13(35.7%) patients, LVEF recovered during the follow‐up course. The median recovery time was 281(IQR [78–358]) days. LVEF on CMR was 35.3 ± 10.5, and three patients exhibited late gadolinium enhancement(LGE) patterns. Sub‐endocardial and mid‐wall uptake pattern types were detected. 18(75%) patients met the Petersen left ventricle non‐compaction cardiomyopathy(LVNC) criteria. Patients with NC/C ratio lower than 2.3 had lower LVEDVi and LVESVi (124.9 ± 35.4, 86.4 ± 7.5, p =.003; 86.8 ± 34.6, 52.6 ± 7.6, p =.006), respectively. The median follow‐up time was 2129 (IQR [911–2634]) days. The primary endpoint‐free 1‐year survival was 88.9% (event rate 11.1%), and 5‐year survival was 75.7% (event rate 24.3%). Conclusion: In a retrospective cohort of PPCM patients, 35.7% of patients' LVEF recovered, and the primary end‐point of free‐5‐year survival was 75%. Twenty‐five patients were assessed with CMR; three of four met the Petersen CMR‐derived LVNC at initial evaluation. [ABSTRACT FROM AUTHOR]

Objective: Germline mutations in the bone morphogenetic protein receptor type-2 (BMPR2) gene are considered to be a major risk factor for pulmonary arterial hypertension (PAH). BMPR2 mutations have been reported in 10%-20% of idiopathic PAH and in 80% of familial PAH cases. The aim of this study was to evaluate the frequency of mutations in the serine/threonine kinase domain of the BMPR2 gene in a group of patients from a single PAH referral center in Turkey. Methods: This cross-sectional study used a DNA-sequencing method to investigate BMPR2 mutations in the serine-threonine-kinase domain in 43 patients diagnosed with PAH [8 with idiopathic PAH and 35 with congenital heart disease (CHD)] from a single PAH referral center. Patients were included if they had a hemodynamically measured mean pulmonary arterial pressure of >25 mm Hg with a mean pulmonary capillary wedge pressure of ⩽15 mm Hg. Patients with severe left heart disease and/or pulmonary disease that could cause pulmonary hypertension were excluded. Associations between categoric variables were determined using the chi-square test. Differences between idiopathic and CHD-associated PAH groups were compared with the unpaired Student's t-test for continuous variables. Results: We detected a missense mutation, [p.C347Y (c.1040G>A)], in one patient with idiopathic PAH in exon 8 of the BMPR2 gene. The mutation was detected in a 27-year-old female with a remarkable family history for PAH. She had a favorable response to endothelin receptor antagonists. No mutations were detected in the exons 5-11 of the BMPR2 gene in the PAH-CHD group. Conclusion: A missense mutation was detected in only one of the eight patients with idiopathic PAH. The BMPR2 missense mutation rate of 12.5% in this cohort of Turkish patients with idiopathic PAH was similar to that seen in European registries. The index patient was a young female with a family history remarkable for PAH; she had a good long-term response to PAH-specific treatment, probably due to the early initiation of the treatment. Genetic screening of families affected by PAH might have great value in identifying the disease at an early stage. [ABSTRACT FROM AUTHOR]

Background: Heart failure (HF) is considered a significant public health issue with a substantial and growing epidemiologic and economic burden in relation to longer life expectancy and aging global population Aims: To determine cost-of-disease of heart failure (HF) in Turkey from the payer perspective. Study Design: Cross-sectional cost of disease study. Methods: In this cost-of-disease study, annual direct and indirect costs of management of HF were determined based on epidemiological, clinical and lost productivity inputs provided by a Delphi panel consisted of 11 experts in HF with respect to ejection fraction (EF) status (HF patients with reduced EF (HFrEF), mid-range EF (HFmrEF) and preserved EF (HFpEF)) and New York Heart Association (NYHA) classification. Direct medical costs included cost items on outpatient management, inpatient management, medications, and nonpharmaceutical treatments. Indirect cost was calculated based on the lost productivity due to absenteeism and presenteeism. Results: 51.4%, 19.5%, and 29.1% of the patients were estimated to be HFrEF, HFmrEF, and HFpEF patients, respectively. The total annual direct medical cost per patient was $887 and non-pharmaceutical treatments ($373, 42.1%) were the major direct cost driver. Since an estimated nationwide number of HF patients is 1,128,000 in 2021, the total annual national economic burden of HF is estimated to be $1 billion in 2021. The direct medical cost was higher in patients with HFrEF than in those with HFmrEF or HFpEF ($1,147 vs. $555 and $649, respectively). Average indirect cost per patient was calculated to be $3,386 and was similar across HFrEF, HFmrEF and HFpEF groups, but increased with advanced NYHA stage. Conclusion: Our findings confirm the substantial economic burden of HF in terms of both direct and indirect costs and indicate that the non-pharmaceutical cost is the major direct medical cost driver in HF management, regardless of the EF status of HF patients.

HEART assist devices , *PULMONARY hypertension , *HEART transplantation , *PULMONARY artery , *CARDIOVASCULAR surgery - Abstract
Pulmonary hypertension ( PH) is considered as a risk factor for morbidity and mortality in patients undergoing heart transplantation. Recently, left ventricular assist device ( LVAD) implantation has been increasingly used in reducing pulmonary artery pressure ( PAP) in patients with PH unresponsive to medical therapy. Herein, we aimed to compare the efficacy of continuous-flow and pulsatile-flow blood pumps on the improvement of PH in mechanical circulatory support patients. Twenty-seven patients with end-stage heart failure who underwent LVAD implantation surgery were enrolled. Fifteen of them (55.6%) had continuous-flow pump (HeartWare Ventricular Assist System, HeartWare, Inc., Miramar, FL, USA), and 12 of them (44.4%) had pulsatile pump (Berlin Heart EXCOR ventricular assist device, Berlin Heart AG, Berlin, Germany). The efficacy of LVADs on the improvement of PH was compared between continuous-flow and pulsatile pumps by the evaluation of systolic PAP, tricuspid annular plane systolic excursion ( TAPSE), right ventricular systolic motion ( RVSM), right ventricular ejection fraction ( RVEF), and grade of tricuspid insufficiency ( TI) for each of the study participants. All of the 15 patients who underwent continuous-flow blood pump implantation surgery (Group 1) were male with a mean age of 46.9 ± 11.7 years, and in pulsatile-flow blood pump implanted participants (Group 2), the mean age was 40.6 ± 16.8 years, all of whom were also male ( P = 0.259). Mean follow-up was 313.7 ± 241.3 days in Group 1 and 448.7 ± 120.7 days in Group 2 ( P = 0.139). In Group 1, mean preoperative and postoperative systolic PAP were measured as 51.7 ± 12.2 mm Hg and 22.2 ± 3.4 mm Hg, respectively, while those in Group 2 were 54.5 ± 7.5 mm Hg and 33.9 ± 6.4 mm Hg, respectively. A significantly greater decrease in systolic PAP was noticed in patients with continuous-flow blood pumps ( P = 0.023); however, no statistically significant difference was found when we considered the change in TAPSE between study groups ( P = 0.112). A statistical significance in the alteration of RVEF, RVSM, and the grade of TI during study visits was not found between the study groups ( P = 0.472, P = 0.887, and P = 0.237, respectively). Although the two studied types of LVADs were found to be effective in reducing PAP in heart transplantation candidates with PH, lesser postoperative systolic PAP values were achieved in patients who underwent continuous-flow pump implantation surgery.

To evaluate the effect of timing of antimicrobial therapy on clinical progress of patients with septic shock. We included 204 adult patients diagnosed with septic shock according to Sepsis-3 criteria between March 2016 and April 2021. One-month survival was evaluated using univariate and logistic regression analysis. Antibiotic treatment was initiated within 1 h of the vasopressors in 26.4 % of patients. One-month mortality did not differ significantly between patients with and without empirical therapy coverage on etiological agents. Univariate factors that significantly affected one-month survival were starting antibiotics at the first hour, the unit where the case was diagnosed with septic shock, SOFA scores, qSOFA scores, and lactate level. In multivariate analysis, diagnosis of septic shock in the Emergency Service, SOFA score ≥11, qSOFA score of three and lactate level ≥4 were significantly associated with one-month mortality. Training programs should be designed to increase the awareness of septic shock diagnosis and treatment in the Emergency Service and other hospital units. Additionally, electronic patient files should have warning systems for earlier diagnosis and consultation. [ABSTRACT FROM AUTHOR]

Left ventricular assist device (LVAD) implantation via left lateral thoracotomy with outflow cannula anastomosis to the descending aorta is an alternative technique that avoids anterior mediastinal planes and requires a single incision. This study compares changes in exercise capacity following LVAD implantation with outflow cannula anastomosis to the descending aorta versus ascending aorta. Adult patients who received a continuous flow centrifugal LVAD implantation and completed both pre‐ and postimplantation cardiopulmonary exercise tests (CPETs) and or 6‐minute walk tests (6MWT) were included. Change in CPET parameters (maximum oxygen intake: vO2max, oxygen uptake efficiency ratio: OUES, ventilatory efficiency ratio: vE/vCO2Slope) and 6MWT distance were compared between ascending and descending aorta anastomosis groups. Ascending and descending aorta anastomosis cohorts included 59 and 14 patients, respectively. Pre‐ and postimplantation CPETs were performed 63 ± 12 days before and 216 ± 17 days following implantation. The improvement in CPET parameters (vO2max, OUES, vE/vCO2Slope) or 6MWT distance was not significantly different between the ascending and descending aorta anastomosis groups. This study found no significant difference in the improvement of CPET parameters or 6MWT distance between LVAD implantation via thoracotomy with outflow cannula anastomosis to descending aorta and standard implantation via sternotomy with outflow cannula anastomosis to ascending aorta.

- Abstract
OBJECTIVE: We retrospectively analyzed case records to identify risk factors for mortality in heart transplant recipients in our center. METHODS: Data of 123 patients (mean age 40.6±14 years and 97 male) transplanted from February 1998 to April 2009 were studied and analyzed. Pre- and intra-operative variables of the 73 patients who survived (Group 1, mean age 39.1±14.6, 58 male) and 50 patients who died (Group 2, mean age 42.6±12.9, 39 male) were compared. For statistical analysis Student t, Mann-Whitney U and Chi-square tests were used. Logistic regression analysis was used to determine independent risk factors for mortality and survival analysis was accomplished using Kaplan-Meier analysis. RESULTS: Overall mortality in the entire population was 40.6% (50/123). Actuarial survival was 74%, 65%, 51% and 31% at 1, 2, 5 and 10 years respectively. Major causes of death after heart transplantation were infections (30%), right ventricular failure (18%), rejection (12%) and sudden cardiac death (12%). Total ischemic time was 176.7±63.3 minutes (range 90-410 minutes). The total cardiopulmonary by-pass (CPB) time (114.3±27.7 vs 126.9±42.1 min, p=0.05), pre-operative creatinine clearance (81.0±31.5 vs 67.2±33.0 ml/min, p=0.02), urea (45.2±18.6 vs 57.8±35.2 mg/dl, p=0.02), and creatinine (1.01±0.25 vs 1.17±0.36 mg/dl, p=0.05) were significantly different between survivors and non-survivors. Group 2 patients had higher transpulmonary gradient (TPG) (9.21±5.16 vs 12.50±8.26 mmHg, p=0.02) as compared with group 1 patients. Logistic regression analysis revealed that preoperative creatinine clearance (OR 0.989, 95% CI 0.973-1.005, p=0.044), creatinine level (OR 2.028, 95% CI 0.288-14.301, p=0.027), total CPB time (OR 1.013, 95% CI 1.000-1.027, p=0.036), and TPG (OR 1.113, 95% CI 0.992 1.249, p=0.045) were the independent predictors of mortality. CONCLUSION: Our data showed that TPG, total CPB time, pre-transplant renal dysfunction are pre-operative and intra-operative risk factors for mortality after heart transplantation.

ATHEROSCLEROSIS , *INFLAMMATION , *HEART blood-vessels , *CORONARY arteries - Abstract
Abstract: Background: Inflammation is one of the key mechanism in the development and progression of coronary artery disease. Myocardial bridging (MB) increases the tendency for development of atherosclerosis. The role of inflammation on the development of atherosclerosis in the MB is not clear. In this study, we investigated the existence of inflammation in the patients who have atherosclerotic plaque in the bridged segment. Methods: This study included 40 patients (group I) presented with stable angina pectoris and detected MB in LAD on coronary angiography and 30 control subjects (group II) with normal coronary angiogram. Patients in group I were divided into two subgroups based on the findings on intravascular ultrasound (IVUS): group IA included 25 patients without atherosclerotic lesion in any coronary artery and group IB included 15 patients with atherosclerotic lesion in addition to MB in bridged segment of LAD. High-sensitivity C-reactive protein (hs-CRP) levels were compared between group I and II and group IA and IB. Results: IVUS showed an atherosclerotic involvement with the proximal segment of MB in 15 patients (=group IB). No plaques were seen in other coronary arteries, in distal of MB or in the bridged segment. With regards to the level of hs-CRP, while no difference was established between group I and group II (1.7±0.4 mg/L vs 1.9±0.6 mg/L, p >0.05), hs-CRP was significantly higher in group IB than in group IA (3.2±0.3 mg/L vs 1.5±0.2 mg/L, p =0.001) and control group (3.2±0.3 mg/L vs 1.9±0.6 mg/L, p =0.03). A significant positive correlation was detected between the hs-CRP and the percentage of atherosclerotic stenosis on IVUS in group IB (R =0.639, p =0.01). Conclusions: These results indicate the presence of a low grade inflammation in patients with atherosclerotic lesion in bridged segment. [Copyright &y& Elsevier]

HUMAN abnormalities , *CARDIAC contraction , *MYOCARDIAL infarction , *VENTRICULAR tachycardia , *ANGIOGRAPHY - Abstract
Objective: Myocardial bridge (MB) is a congenital anomaly characterized by narrowing during systole of some of the epicardial coronary arterial segments running in the myocardium. Although, it is considered as a benign anomaly, it may lead to such complications as acute myocardial infarction, ventricular tachycardia, syncope, atrioventricular block and sudden cardiac death. In this study, we aimed to investigate demographic, clinical and angiographic characteristics of the patients with MB found on coronary angiography. Methods: The present study included 71 patients with MB found on coronary angiographies performed in our institution between January 1999 and September 2003. Based on the findings on angiography, the patients were subdivided into group A (n=41) and group B (n=30). The patients in the group A had no atherosclerotic lesion and the patients in the group B had coronary artery disease in addition to MB. Angiographic, demographic and clinical characteristics of both groups were compared. Results: There were no differences between two groups in distribution of gender and risk factors of coronary artery disease whereas mean age of the patients in the group A was lower (47±5 years vs 55±11 years, p=0.01). Frequency of two or more risk factors for coronary artery disease in a particular patient was significantly higher in the group B (55% vs 30%, p=0.03). Myocardial bridge was located at proximal or mid segments of left anterior descending artery (LAD) in 40 patients whereas its presence in both LAD and right coronary artery was found only in one patient in group A. Mean bridging percent was 43±27% in group A. Localization of MB was LAD in 29 patients of group B. One patient with severe aortic valve stenosis in this group had MB at first septal branch. Mean bridging percent was 70±25% in group B, which was significantly higher than in group A (p<0.05). Atherosclerotic narrowing developed in only LAD in 14 patients, LAD and other vessels in 7 patients and in the vessels without MB in 9 patients. In patients with MB in LAD atherosclerotic narrowing of vessel developed proximally to the MB. Clinically, stable angina pectoris was seen more frequently in group A than group B (70% vs 35%, p=0.01), whereas the frequency of acute coronary syndrome was higher in group B (65% vs 30%, p=0.04). In regard to therapeutic approach, more patients in the group A received medical management (80% vs 50%, p=0.01), while more patients in the group B underwent surgical and percutaneous interventions (50% vs 18%, p=0.04). Conclusion: Myocardial bridge probability should be considered in young patients presenting with angina or if the same symptoms are persistent in the patients without more than one risk factor for coronary artery disease. Myocardial bridge may initiate the development of atherosclerotic lesion or may facilitate progression of atherosclerosis in the proximal segment of the vessel. The risk of acute coronary syndrome rises when atherosclerosis is superimposed on MB. Myocardial bridge should be considered in the young patients, presenting with angina or its equivalents without atherosclerotic lesions on coronary angiography. [ABSTRACT FROM AUTHOR]

Objective: The relationship between myocardial bridging (MB) and ischemic heart disease is still controversial. In this study, we aimed to evaluate the existing atherosclerosis and noninvasive endothelial function of brachial artery in patients with MB. Methods: The present study included 50 patients (group I) who had MB in left anterior descending (LAD) on coronary angiography. All of the coronary artery segments were evaluated by intravascular ultrasound (IVUS). Endothelial function was assessed with measurement of flow-mediated dilatation (FMD) and nitrate-dependent dilatation in the brachial artery. The study also included 30 healthy control subjects (group II). Patients in the group I were further subdivided into two subgroups based on the findings on IVUS: group IA included 20 patients without atherosclerotic lesions and group IB included 30 patients with atherosclerotic coronary artery disease in addition to MB. Results: FMD values were found to be significantly lower in the patients with MB (group I) than in the control (6.4 ± 3% vs 11 ± 4%, P <0.001). In regard to FMD values in subgroups, FMD was 7 ± 2% in the group IA and 5.8 ± 1% in the group IB (P = 0.023). On IVUS, atherosclerotic plaque was found proximal to the bridge in the same coronary artery segment in addition to MB in 75% of the patients in group I (group IB). No atherosclerotic plaque was found in within or distal segments of MB. Conclusion: Endothelial function is impaired in patients with MB and there is an increased tendency for atherosclerosis proximal to the bridge in the patients with MB. Endothelial dysfunction is more severe in the patients with atherosclerosis proximal to the bridge. [ABSTRACT FROM AUTHOR]

PERCUTANEOUS balloon valvuloplasty , *MITRAL stenosis , *MITRAL valve , *RESEARCH , *DOPPLER echocardiography - Abstract
The purpose of this study was to investigate whether there is any association between mitral leaflet motion (LMI) and leaflet thickness index (LTI) scores and the rate of restenosis 3 months after successful mitral balloon valvuloplasty. The study population consisted of 46 patients with symptomatic rheumatic mitral stenosis who underwent balloon valvuloplasty (37 women, 9 men;mean age, 36 ± 9 years). Two-dimensional and Doppler echocardiography were performed in all patients on the day before, immediately after, and 3 months after valvuloplasty. The severity of restriction of leaflet motion and the severity of leaflet thickening were classified into grades of mild (a score of 0), moderate (a score of 1), and severe (a score of 2). Subvalvular disease and commissural involvement were homogeneous in all patients. Before and immediately after mitral balloon valvuloplasty, there were no significant differences in mitral valve area among the groups with different LMI and LTI scores. However, at 3 months after valvuloplasty, reduction in mitral valve area was more significant in patients who had higher pre-procedural LMI and LTI scores (P < 0.05). The rates of early restenosis were 0 with a total score of 0, 14.2% with a total score of 1--2, and 32% with a total score of 3. In conclusion, quantitative assessment of LMI and LTI scores by 2-dimensional echocardiography may be helpful in predicting early restenosis after mitral balloon valvuloplasty. Early reduction in mitral valve area is significant in patients who have higher total LMI and LTI scores. [ABSTRACT FROM AUTHOR]

Objective: Ischemic heart disease accounts for 50% of all cardiovascular deaths and is the leading cause of congestive heart failure. Medical therapy, cardiac assist devices and surgical procedures including heart transplantation have limited efficiency and availability. Stem cell transplantation represents a new therapeutic opportunity for such patients. Method: Six patients with the diagnosis of ischemic cardiomyopathy were included in this study. All of the patients had clinical, radiological and echocardiographic signs of heart failure, and reduced left ventricular ejection fraction (LVEF≤25%). They underwent coronary angiography and stress tests with dobutamine echocardiography, thallium scintigraphy and positron emission tomography to assess myocardial ischemia and viability. Peripheral stem cells were mobilized and collected by apheresis. They were transplanted into areas of injury with open-heart surgery. To increase blood flow to the engrafted areas, coronary artery by-pass surgery was also performed. Results: The patients were followed at least for 4 months. Echocardiography, thallium scintigraphy and positron emission tomography were repeated after at least 6 weeks following surgery. There was a significant increase in life quality and NYHA class. Some benefit was documented on echocardiography, thallium scintigraphy, and positron emission tomography. Conclusion: This approach opens a new window in the treatment of ‘no hope’ patients with congestive heart failure. [Copyright &y& Elsevier]

Purpose: The aim of this study was to evaluate the associations of sonographic and sonoelastographic parameters with clinical cardiac parameters, as well as to assess their value in predicting survival in patients with pulmonary arterial hypertension (PAH). Methods: Thirty-six patients with PAH and normal liver function were prospectively enrolled in this prospective study along with 26 healthy controls, all of whom underwent ultrasound and point shear wave elastography examinations. Additionally, the portal vein pulsatility index (PVPI), inferior vena cava collapsibility index, and clinical cardiac variables were obtained in PAH patients. The values of hepatic (LVs) and splenic shear wave velocity (SVs) were compared between PAH patients and controls. The relationships between all sonographic and clinical parameters in the PAH patients were analyzed. Furthermore, their prognostic value in predicting survival was investigated. Results: LVs values in PAH patients (median, 1.62 m/s) were significantly higher than in controls (median, 0.99 m/s), while no significant difference was observed in SVs values. Patients with higher grades of tricuspid regurgitation (TR) had significantly different values of PVPI (P=0.010) and sonoelastographic parameters (P<0.001 for LVs and P=0.004 for SVs) compared to those with less severe TR. Tricuspid annular plane systolic excursion values were the only investigated parameter found to be associated with survival (hazard ratio, 0.814; 95% confidence interval, 0.694 to 0.954; P=0.011). Conclusion: Our results demonstrated a direct association between cardiac congestion (i.e., the severity of TR) and liver stiffness, which should be kept in mind during the assessment of fibrosis in patients with PAH.

Abstract: Background: Levosimendan is a novel positive inotropic calcium sensitizer agent used in acute heart failure. In acute heart failure, it improves hemodynamic parameters more favorably than the conventional positive inotropes. In this study, the effect levosimendan on E/E′ ratio as a non-invasive indicator of LV filling pressure was evaluated compared to dobutamine in a prospective, randomized, patient-blind manner. Methods: Patients with an LVEF<40% admitting with acute heart failure attack with ischemic origin were included to this study. Patients were randomized to levosimendan (n =30, mean age: 64±10 years, 63% male) or dobutamine (n =32, mean age: 66±8 years, 54% male) groups. The ratio of the peak E wave velocity taken from mitral inflow with PW Doppler to the peak E′ wave velocity taken from mitral lateral annulus with tissue Doppler was determined. Pre-treatment and 24-hour after the treatment E/E′ ratios were calculated and then compared in both groups. Results: Age, gender, concomitant medications were similar in both groups (p >0.05). There was no difference for pre-treatment baseline E/E′ ratios between levosimendan and dobutamine groups (15.7±4.0 vs 15.2±7.5 respectively, p =0.1). There were significant reductions in post-treatment E/E′ ratios in levosimendan (15.7±4.0 vs 9.3±2.8, p =0.01) and dobutamine groups (15.2±7.5 vs 12.9±5.6, p =0.04). However, the reduction in levosimendan group was greater compared to dobutamine group (p =0.01). Conclusions: Levosimendan causes a greater reduction of E/E′ ratio compared to dobutamine in acute systolic left heart failure. This may explain the more favorable hemodynamic effects of levosimendan when compared to conventional positive inotropics in patients with systolic left heart failure. [Copyright &y& Elsevier]

Testosterone deficiency is associated with mortality in patients with heart failure; however, its effects on patients undergoing Left Ventricular Assist Device (LVAD) implantation are unclear. We investigated the role of total testosterone (TT) and free testosterone (FT) levels on mortality undergoing LVAD implantation. Between December 2010 and December 2014, 101 consecutive male patients who underwent LVAD implantation and had plasma testosterone measurement (TT and FT) in the last month before operation were included in the study. Demographics, follow-up, and mortality data were analyzed retrospectively. The mean age of the patients was 51.7 ± 11 years. TT and FT levels were in the below normal range of 31.6% (n = 32) and 65.3% (n = 66) of the patients, respectively. The mean follow-up time was 355 ± 268 days, and 32 (31%) patients died during follow-up. Cumulative survival rates were significantly worse in patients with low TT and FT than patients in the normal range (P <.001 and P =.029, respectively). Multivariate analysis after adjustment for clinical variables, age, albumin, C-reactive protein, total cholesterol, chronic kidney disease, diabetes mellitus (DM), and leukocytosis showed that low TT and FT were independently associated with poor survival (HR, 3.680; 95% CI, 1.615-8.385 P =.002 and HR, 3.816; 95% CI, 1.279-11.383, P =.016, respectively). Low TT and FT levels were independent risk factors for mortality in patients with LVAD. [ABSTRACT FROM AUTHOR]

BRAIN natriuretic factor , *NATRIURETIC peptides - Abstract
Natriuretic peptides have long been introduced into clinical practice. These biomarkers have certainly been shown to provide useful information in the diagnosis, prognosis and risk stratification in heart failure and also may have a role in the guidance of heart failure therapy. Although, there are some limitations in using of these markers such as lack of specificity, aging, renal dysfunction or obesity, among the huge number of candidates for heart failure biomarkers, only natriuretic peptides are currently widely used in daily clinical practice in heart failure. Recent heart failure guidelines recognize natriuretic peptides as an essential tool in the new diagnostic and therapeutic algorithms. Furthermore, natriuretic peptides are not only used in the diagnosis or prognosis of heart failure, but also these biomarkers are referred to have some potential role in primary prevention, cardio-oncology, advanced heart failure, assessment of response to cardiac resynchronization therapy, pulmonary arterial hypertension, acute coronary syndromes, atrial fibrillation and valvular heart disease. In this article, natriuretic peptides have been reviewed for their updated information and new recommendations in heart failure and also potential role of these biomarkers in the management of various clinical conditions have been addressed in the form of expert opinion based on the available data in the literature.

This article updates the Heart Failure Association of the European Society of Cardiology (ESC) 2007 classification of advanced heart failure and describes new diagnostic and treatment options for these patients. Recognizing the patient with advanced heart failure is critical to facilitate timely referral to advanced heart failure centres. Unplanned visits for heart failure decompensation, malignant arrhythmias, co-morbidities, and the 2016 ESC guidelines criteria for the diagnosis of heart failure with preserved ejection fraction are included in this updated definition. Standard treatment is, by definition, insufficient in these patients. Inotropic therapy may be used as a bridge strategy, but it is only a palliative measure when used on its own, because of the lack of outcomes data. Major progress has occurred with short-term mechanical circulatory support devices for immediate management of cardiogenic shock and long-term mechanical circulatory support for either a bridge to transplantation or as destination therapy. Heart transplantation remains the treatment of choice for patients without contraindications. Some patients will not be candidates for advanced heart failure therapies. For these patients, who are often elderly with multiple co-morbidities, management of advanced heart failure to reduce symptoms and improve quality of life should be emphasized. Robust evidence from prospective studies is lacking for most therapies for advanced heart failure. There is an urgent need to develop evidence-based treatment algorithms to prolong life when possible and in accordance with patient preferences, increase life quality, and reduce the burden of hospitalization in this vulnerable patient population.

Objective: The present study was designed to evaluate the characteristics of pulmonary hypertension (PH) and adult cardiology practice patterns for PH in our country. Methods: We evaluated preliminary survey data of 1501 patients with PH (females, 69%; age, 44.8±5.45) from 20 adult cardiology centers (AdCCs). Results: The average experience of AdCCs in diagnosing and treating patients with PH was 8.5±3.7 years. Pulmonary arterial hypertension (PAH) was the most frequent group (69%) followed by group 4 PH (19%), group 3 PH (8%), and combined pre- and post-capillary PH (4%). PAH associated with congenital heart disease (APAH-CHD) was the most frequent subgroup (47%) of PAH. Most of the patients' functional class (FC) at the time of diagnosis was III. The right heart catheterization (RHC) rate was 11.9±11.6 per month. Most frequently used vasoreactivity agent was intravenous adenosine (60%). All patients under targeted treatments were periodically for FC, six-minute walking test, and echo measures at 3-month intervals. AdCCs repeated RHC in case of clinical worsening (CW). The annual rate of hospitalization was 14.9±19.5. In-hospital use of intravenous iloprost reported from 16 AdCCs in CWs. Bosentan and ambrisentan, as monotreatment or combination treatment (CT), were noted in 845 and 28 patients, respectively, and inhaled iloprost, subcutaneous treprostinil, and intravenous epoprostenol were noted in 283, 30, and four patients, respectively. Bosentan was the first agent used for CT in all AdCCs and iloprost was the second. Routine use of antiaggregant, anticoagulant, and pneumococcal and influenza prophylaxis were restricted in only two AdCCs. Conclusion: Our nationwide data illustrate the current status of PH regarding clinical characteristics and practice patterns. [ABSTRACT FROM AUTHOR]

Significant mitral regurgitation (MR) is thought to decrease after left ventricular assist device (LVAD) implantation, and therefore repair of mitral valve is not indicated in current practice. However, residual moderate and severe MR leads to pulmonary artery pressure increase, thereby resulting in right ventricular (RV) dysfunction during follow-up. We examined the impact of residual MR on systolic function of the right ventricle by echocardiography after LVAD implantation. This study included 90 patients (mean age: 51.7 ± 10.9 years, 14.4% female) who underwent LVAD implantation (HeartMate II = 21, HeartWare = 69) in a single center between December 2010 and June 2014. Echocardiograms obtained at 3-6 months and over after implantation were analyzed retrospectively. RV systolic function was graded as normal, mild, moderate, and severely depressed. MR (≥moderate) was observed in 43 and 44% of patients at early and late period, respectively. Systolic function of the RV was severely depressed in 16 and 9% of all patients. Initial analysis (mean duration of support 174.3 ± 42.5 days) showed a statistically significant correlation between less MR and improved systolic function of RV ( P = 0.01). Secondary echocardiographic analysis (following a mean duration of support of 435.1 ± 203 days) was also statistically significant for MR degree and RV systolic dysfunction ( P = 0.008). Residual MR after LVAD implantation may cause deterioration of RV systolic function and cause right-sided heart failure symptoms. Repair of severe MR, in selected patients such as those with severe pulmonary hypertension and depressed RV, may be considered to improve the patient's clinical course during pump support.

Background Right ventricular ( RV) dysfunction is a major determinant of outcomes in patients with pulmonary arterial hypertension ( PAH), although the optimal measure of RV function is poorly defined. We evaluated the utility of RV free-wall speckle tracking strain as an assessment tool for RV function in patients with PAH who are already under specific treatment compared with conventional echocardiographic parameters and investigated the relationship of RV free-wall strain with clinical hemodynamic parameters of RV performance. Methods Right ventricular free-wall strain was evaluated in 92 patients (Group-1 and Group-4 pulmonary hypertension) who were on PAH-specific treatment for at least 3 months. Right atrial ( RA) area, RV FAC, TAPSE, tricuspid S, functional class, 6-minute walking distance, and NT-pro BNP were studied. The mean duration of follow-up was 222±133 days. Results All patients were under PAH-specific treatment, and mean RV free-wall strain was −13.16±6.3%. RV free-wall strain correlated well with functional class ( r=.312, P=.01), NT-pro BNP ( r=.423, P=.0001), RA area ( r=.427, P=.0001), FAC ( r=−.637, P=.0001), TAPSE ( r=−.524, P=.0001), tricuspid S ( r=−.450, P=.0001), 6-minute walking distance ( r=−.333, P=.002). RV free-wall strain significantly correlated with all follow-up adverse events, death, and clinical right heart failure ( RHF) ( P=.04, P=.03, P=.02, respectively). According to the receiver operator characteristic analysis, the cutoff value for RV free-wall strain for the development of clinical RHF was −12.5% (sensitivity: 71%, specificity: 67%) and for all cardiovascular adverse events (death included) was −12.5% (sensitivity: 54%, specificity: 64%). Conclusion Assessment of RV free-wall strain is a feasible, easy-to-perform method and may be used as a predictor of RHF, clinical deterioration, and mortality in patients already under PAH-specific treatment.

Background: Patients who underwent lung resection in our clinic were retrospectively investigated in terms of development of postoperative cardiac complications.Methods: The file records of 207 patients who underwent lung resection between the years 2010 and 2014 were reviewed. One hundred and eighteeen (118) (57%) of the patients were evaluated by the preoperative cardiologist and the risk level of the patients was determined according to the Lee index. Postoperative cardiac complication relation was compared with each parameter.Results: The difference between the mean age of the patients with and without complication was statistically significant (p=0.024). When the patients were grouped as over and under 65 years old, the risk of developing postoperative complications was higher and statistically significant (p=0.015) in patients over 65 years of age. When the patients were evaluated in line with the presence of additional disease, smoking and electrocardiogram (ECG) findings, patients with hypertension developed more complications than those without hypertension (p=0.002). When the logistic regression was adjusted according to age and sex, the development of cardiac complications in patients with hypertension was 3.25 times greater.Conclusions: It should be kept in mind that the presence of hypertension in patients who will undergo lung resection and advanced age increases the risk of cardiac complications and that preoperative cardiology care may be appropriate for these patients.

- Abstract
A 54-year-old man with a history of chest pain and dyspnea for 15 days was admitted to our hospital. Diagnostic evaluation, which included transthoracic echocardiography and computed tomographic scanning, revealed an ascending aortic aneurysm (6 cm in diameter), severe aortic valve insufficiency, and possible aortic dissection. The coronary arteries could not be seen, because the catheter could not be placed in their orifices. The patient was taken to the operating room. Intraoperative transesophageal echocardiography revealed an intimal flap in the ascending aorta. The proximal part of the f lap was attached to the aortic wall at the level of the coronary ostia, and its distal part was circumferentially free (Fig. 1). The flap was prolapsing into the left ventricular outflow tract through the aortic valve leaflets at every diastole (Fig. 2A) and moving back to the aortic lumen at systole (Fig. 2B). The patient underwent aortic root replacement by means of the Bentall procedure. During surgical exploration, we saw that the dissection involved the commissures and the orifice of the right coronary ostia and that it ended just proximal to the aortic clamp, which did not necessitate the use of hypothermic circulatory arrest (Fig. 3). The patient was discharged from the hospital 6 days after the operation without complication [ABSTRACT FROM AUTHOR]

- Abstract
Heart failure (HF) is a progressive disorder associated with impaired quality of life, high morbidity, mortality and frequent hospitalization and affects millions of people from all around the world. Despite further improvements in HF therapy, mortality and morbidity remains to be very high. The life-long treatment, frequent hospitalization, and sophisticated and very expensive device therapies for HF also leads a substantial economic burden on the health care system. Therefore, implementation of evidence-based guideline-recommended therapy is very important to overcome its worse clinical outcomes. However, HF therapy is a long process that has many drawbacks and sometimes HF guidelines cannot answers to every question which rises in everyday clinical practice. In this paper, commonly encountered questions, overlooked points, controversial issues, management strategies in grey zone and problems arising during follow up of a HF patient in real life clinical practice have been addressed in the form of expert opinions based on the available data in the literature.

Objective: We aimed to evaluate left atrium (LA) phasic functions and relation with N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and symptomatic states of the patients with hypertrophic cardiomyopathy (HCM). Methods: Left atrial volume was calculated at end-systole (Vmax), end-diastole and pre-atrial contraction by echocardiography in 75 patients with HCM and 75 control subjects. Left atrial ejection fraction (LAEF), expansion index (LAEI), active emptying volume index (LAAEVI) and fraction (LAAEFr), passive emptying volume index (LAPEVI) and fraction (LAPEFr) were calculated. NT-proBNP levels were measured. Results: Left atrial active emptying volume (LAAEV) positively correlated with Vmax (r=0.343, p=0.003) up to a point, but then reached a plateau with larger LA volumes in HCM group. The LAAEFr was the only variable which was similiar between asymptomatic patients and controls, but was significantly decreased in symptomatic patients (p<0.05). NT-proBNP was correlated with LAEF (r=-0.32, p=0.005), LAEI (r=-0387, p=0.001), and LAAEFr (r=-0.25, p=0.035) but not related with LAPEFr (p=0.4). In receiver operating characteristic curve analysis an NT-proBNP cut-off value of 1415 pg/mL identified reduced LAEF with 87% specificity and 59% sensitivity [AUC=0.77 (95% CI: 0.65-0.89), p=0.004], a cut-off value of 820 pg/mL predicted impaired LAEI with 81% specificity ve 67% sensitivity [AUC=0.78 (95% CI: 0.66-0.9), p<0.001]; while a cut-off value of 1320 pg/mL predicted impaired LAAEFr with 76% specificity and 67% sensitivity [AUC=0.79 (95% CI: 0.68-0.91), p=0.02]. Conclusion: In HCM, LA phasic functions alter according to the Frank-Starling mechanism indicating occurrence of a secondary atrial myopathy. Impairment of LA booster pump function seems to be associated with appearance of symptoms and NT-proBNP levels predict the deterioration of LA reservoir and pump functions in HCM population.

HEART diseases , *VENTRICULAR septal defects , *GENETIC disorders , *HEMODYNAMICS , *HEART septum abnormalities - Abstract
Objective: In this study, patients admitted with the diagnosis of Eisenmenger syndrome (ES) in a tertiary referral center were analyzed. Methods: The data of 20 consecutive patients (mean age: 27.6+1.8 years, 7 male and mean follow-up time: 35.6±9.1 months) with ES were retrospectively analyzed. Demographic characteristics, symptoms, physical examination, laboratory and hemodynamic parameters were analyzed at the time of first admission. Results: The most frequent underlying heart diseases were ventricular septal defect (VSD) with complex congenital disease (n:8, 40%) and isolated VSD (n:7, 35%). 6-minute walking test distance was 347.9±33.7 meters and 15 patients (75%) had a functional capacity of NYHA Class III, at the time of admission. ES was diagnosed with catheterization in all patients and mean systolic pulmonary arterial pressure measured by catheterization was 112±6.8 mmHg. Pulmonary function tests, FVC (forced vital capacity), FEV1 (forced expiratory volume), FEV1/FVC values were respectively, 3.1±0.4, 2.5±0.4 L and 76.7±3.3%. Metabolic tests were performed in all patients at the first visit. Mean VO2 max was 16.7 ±1.0 ml / kg/min and VE/VCO2 rate was 53.9±3.2%. Although PH and partial pressure of carbon dioxide levels were within normal range in blood gas analysis, oxygen saturation and partial pressure of oxygen levels were low. Conclusion: The most common underlying heart disease of ES patients is VSD. In this cases exercise capacity is restricted and this restriction is reflected in laboratory parameters.

Objective: To evaluate postgraduate training period, social life and problems of cardiology residents in Turkey by using a questionnaire form and to compare with the core curriculum of European Society of Cardiology for general cardiology. Methods: Overall, 529 residents of cardiology ages in range of 24-35 years (mean age: 26.5±2.0 years, 81.4% male) participated as volunteers in this cross-sectional survey study. An 86-item questionnaire form was used to evaluate the education process, capacity of knowledge and skill and social effectiveness level of participants. The questionnaire were composed both closed- and open-ended questions. The questionnaire form was filled in with the face-to-face communication method. The data of survey were compared with the core curriculum of European Society of Cardiology for general cardiology training period. Chi-square or Fischer exact test was used for statistical analysis. Results: The participants were working in various university hospitals (70.3%) and training-research (state) hospitals in 31 different provinces in Turkey (40.8% in Marmara region). They visited 40±10 outpatients and 10±5 hospitalized pts daily in the clinics. The 3-5 residents worked at the clinic on night shifts and mostly (89%) 8 or more night shifts per month were held in their first training years. During first three-years of training 76% of residents have performed echocardiography, 40.8%-transesophageal echocardiography and 10%-intraoperative echocardiography. The 84.3% of them evaluated exercise tests, 76.4%-Holter electrocardiography and 53.3%-tilt-table tests. The rate of residents working in coronary angiography laboratories was 54.3%. The 53.7% of residents performed coronary angiography and 64%-only in the 4th year of their training. The number of coronary angiography performance was under expected when compared with European Society of Cardiology curriculum. The 18.5% of residents were participated as assistant researcher in an international multi-center study and only 10% had an article published in national journals (4.3% published in Science Citation Index). The 30.6% considered the cardiology training period in their centers to be insufficient, whereas 37.4% found it partially sufficient and 31.9% sufficient. Only 32.9% of participants could dedicate time for social activities. Conclusion: According to the referred core curriculum of ESC for general cardiology the training of cardiology residents in non-invasive applications is adequate however coronary angiography applications are slightly insufficient in Turkey. In addition, the number of publications per capita is quiet low. [ABSTRACT FROM AUTHOR]

- Abstract
Pulmonary arterial hypertension (PAH) is an uncommon disorder that may be hereditable, idiopathic or associated with conditions like drug exposure, connective tissue disease, HIV infection or congenital heart disease. Familial disease are usually due to mutations in the bone morphogenic protein receptor type 2 (BMPR2), activin-like kinase-type 1 (ALK1) and endoglin (ENG). Functional and structural changes in the pulmonary vasculature lead to increased pulmonary vascular resistance. Vascular remodeling involves endothelial dysfunction, activation of fibroblasts and smooth muscle cells and recruitment of circulating progenitor cells. Vasoconstriction has also been shown to affect the remodeling process. Genetics, cellular and molecular basis of PAH are discussed in the paper. [ABSTRACT FROM AUTHOR]

HEART failure patients , *DIURETICS , *VASODILATORS , *HYPERTENSION , *MYOCARDIAL depressants - Abstract
Acute heart failure syndrome is a heterogeneous group, which requires distinct therapeutic approaches. Diuretics and/or vasodilators for patients with high blood pressure and inotropic agents for patients with low left ventricular ejection fraction and evidence of hypoperfusion are kept in the forefront. Early initiation of therapy along with accurate and early diagnosis in acute heart failure reduces mortality and morbidity significantly. Therefore, it is critically important to develop algorithms, which could easily be followed by all physicians. In this paper, in parallelism with heart failure guidelines and utilizing data of the clinical studies, performed by colleagues of our country in this area, therapeutic algorithms compatible with the conditions of our country are suggested for distinct clinical presentations of acute heart failure.

- Abstract
Hydatid disease can occur anywhere in the body and can demonstrate different imaging features that vary according to growth stage, associated complications, and affected tissue. Cardiovascular system involvement of hydatid disease is very rare. In this article, we present the cardiac magnetic resonance (MR) and thorax computed tomography (CT), MR angiography (MRA) findings of hydatid cysts located in the right ventricle and pulmonary arteries after surgical removal of hepatic hydatid cysts.
