OBJECTIVE: Gamma-glutamyl transferase (GGT) to albumin ratio (GAR) has been shown to be helpful to diagnose and determine the severity of coronary artery disease (CAD). Coronary computed tomography angiography (CCTA) is a guide recommended non-invasive test that provides information about the presence, severity, and morphology of coronary plaques. In this study, our main aim was to investigate the relationship between the presence, morphology, and severity of coronary plaques detected via CCTA and GAR in patients with low to moderate risk for undiagnosed CAD. METHODS: Nine hundred and sixty six patients were included who underwent CCTA. The severity of CAD and plaque morphology were investigated. CT-adapted Leaman score (CT-LeSc) was calculated to determine the extent of the CAD. The study population was further evaluated in three groups according to tertiles of GAR. RESULTS: Atherosclerotic plaques were more common in the male gender and older patients with conventional cardiovascular risk factors. GAR was significantly lower in patients with normal CCTA than in patients with a non-obstructive plaque or obstructive plaque on CCTA. Patients in upper GAR tertiles had a higher coronary calcium score (CACS) and CT-LeSc. GAR was one of the independent predictors to predict severe stenotic plaque and high CACS. CONCLUSION: GAR can independently predict the presence, extent, and severity of CAD determined by CT-LeSc. We believe as a cheap, safe, and widely available tool, GAR would be useful in the diagnosis of CAD.

Purpose Left atrial (LA) longitudinal strain (S) has been proposed as a superior, non-invasive parameter over LA volumetric assessment. LAS has diagnostic and prognostic value in many cardiovascular pathologies. Nevertheless, the acute effect of hemodynamic changes on LAS indices is not well-established. We sought to identify volume independent physiomechanical changes in LA and interrelation between LA and left ventricular (LV) strain indices following a large amount of fluid loss provided by hemodialysis. Methods Seventy-five patients between 18 and 85 years of age under hemodialysis therapy were included. The echocardiographic images were obtained before and after hemodialysis. Phasic LAS and LV global longitudinal strain (GLS) were calculated. The impact of volume depletion on echocardiographic measurements and their temporal correlation were calculated. Results LV and LA dimensions,volumes and LV, LA reservoir, and conduit deformation showed a significant decrease after hemodialysis. No significant change was observed for LAS(contraction) (p = 0.203). The ultrafiltrated volume was significantly correlated with the changes in LVGLS (r = 0.75, p < 0.001), and LAS(reservoir) (r = 0.81, p < 0.001) and LA total emptying volume (r = 0.80, p < 0.001). Absolute changes in LAS(reservoir) and LVGLS were strongly correlated (r = 0.83, p < 0.001). There was no correlation between absolute changes in LAS(contraction) and LVGLS or ultrafiltrated volume (p = NS, both). Conclusion LA reservoir and conduit LS are highly volume dependent strain parameters and are strongly correlated with LV deformation along with ultrafiltrated volume. Acute excessive volume depletion or LV deformation have no influence on LAS(contraction). It is important to identify independent easily accessible functional parameters for the LA which would improve clinical evaluation.

Aims There is an increasing trend evaluating the role of non-pulmonary vein (PV) triggers to improve ablation outcomes in persistent atrial fibrillation (AF) as pulmonary vein isolation (PVI) strategy alone has modest outcomes. We investigated the long-term safety and efficacy of left atrial appendage isolation (LAAi) in addition to PVI using cryoballoon (CB) in persistent AF. Methods and results In this multicentre retrospective analysis, we included a total of 193 persistent AF patients (mean age: 60 ± 11 years, 50.3% females) who underwent PVI and LAAi using CB. Baseline and follow-up data including electrocardiography (ECG), 24 h Holter ECGs, and echocardiography were recorded for all patients. Atrial tachyarrhythmia (ATa) recurrence was defined as the detection of AF, atrial flutter, or atrial tachycardia (≥30 s) after a 3-month blanking period. At a median follow-up of 55 (36.5–60.0) months, 85 (67.9%) patients with PVI + LAAi were in sinus rhythm after the index procedure. Ischaemic stroke/transient ischemic attack occurred in 14 (7.2%) patients at a median of 24 (2–53) months following catheter ablation. Multivariate regression analysis revealed heart failure with preserved ejection fraction [hazard ratio (HR) 2.29, 95% confidence interval (CI) 1.04–5.02; P = 0.038], male gender (HR 0.53, 95% CI 0.29–0.96; P = 0.037), and LA area (HR 1.04, 95% CI 0.53–1.32; P = 0.023) as independent predictors of ATa recurrence. Conclusion Our findings demonstrated that the LAAi + PVI strategy using CB had acceptable long-term outcomes in patients with persistent AF. Systemic thrombo-embolic events are an important concern throughout the follow-up, which were mostly observed in case of non-adherence to anticoagulants.

Purpose Cryoballoon (CB) and radiofrequency (RF) ablation techniques have similar outcomes for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF). However, there is limited data about the impact of different ablation strategies in patients with left common pulmonary vein (LCPV). Our aim was to compare the safety and efficacy of RF and CB ablation in AF patients with LCPV. Methods One hundred and twenty-seven (n = 80 CB and n = 47 RF) AF patients with LCPV detected by preprocedural computerized tomography (CT) were included in the study. Ostial dimensions and trunk distance were measured in all patients. Atrial tachyarrhythmia (ATa) recurrence was defined as detection of AF, atrial flutter, or atrial tachycardia (>= 30 s) after a 3-month blanking period. Results There was no significant difference in acute procedural success rates for PVI (97.5% in CB and 97.9% in RF, respectively, P = 0.953) and complication rates were similar between the groups (6 (7.5%) in CB and 4 (8.5%) in RF, respectively, P = 1.000). During a median follow-up of 20.7 (4.8-50.2) months for CB and 20.5 (6.2-36.0) months for RF, ATa recurrence was 35.0% and 38.2%, respectively (P = 0.777). Multivariate analysis did not reveal any of the morphologic parameters of LCPV as a significant predictor of ATa recurrence. Conclusions Our findings demonstrated that both CB and RF ablation techniques have similar efficacy and safety in AF patients with LCPV during the mid-term follow-up.

Background The aim of this study was to investigate the impact of vitamin K antagonist (VKA) therapy on coronary artery calcification (CAC) by comparing long-term VKA users with metallic prosthetic valves (MPVs) and VKA-free patients undergoing coronary calcium scoring for cardiovascular (CV) risk stratification. Methods A total of 108 patients (43 VKA users with MPV and 65 gender-, age-, and risk-factor-matched VKA-free patients) were included in the study. CAC was determined via computed tomography (CT) and quantified on the basis of the Agatston score. The VKA group comprised patients who had an MPV for longer than 5 years, which entailed long-term VKA use. Results Long-term VKA users had more calcified coronary arteries compared with the control group (178.1 +/- 278 vs. 61.1 +/- 130.6,p= 0.01). There was no difference between groups in terms of traditional CV risk factors. The mean duration of VKA use was 15 +/- 7 years for the patients with MPV. There was no correlation between the duration of VKA use and mean Agatston score (r= 0.2,p= 0.215). Conclusion With its unique selection of patient groups, our study extends the findings of previous research that long-term VKA use is related to CAC as detected via CT scanning. The longer and more potent VKA regimen required for MPV patients is the primary cause of CAC in this group.

Objectives: Vitamin D plays a pivotal role in cardiovascular system and its deficiency is related to various of cardiovascular disorders. We investigated the association between serum vitamin D level and coronary artery ectasia formation. Methods: Our study included 45 patients with coronary artery ectasia and 55 patients with normal coronary artery. Vitamin D and parathyroid hormone levels were obtained before coronary angiography. Results: Baseline characteristic features were similar between groups. The Vitamin D levels and serum calcium levels were significantly lower in the coronary artery ectasia group compare to control group (respectively; 15.6 ng/ml vs. 12.0 ng/ml; p=0.002 and 9,52 vs. 9.0; p

Since its recognition in December 2019 as a cause of pneumonia, SARS-CoV-2 infection has rapidly spread globally, causing a pandemic. Although it is an infectious disease, several distinct manifestations have been described in the setting of COVID-19, which result from the immune perturbations caused by this new Coronavirus. The heart is frequently involved in COVID-19 and is associated with severe outcomes. Pericarditis is rarely reported in COVID-19 patients and no reports on its treatment and outcome are available so far. Herein, we present a 33-year-old man with COVID-19-related pericarditis (COVID-19-RP) who was unresponsive to colchicine and nonsteroidal anti-inflammatory drugs, but was successfully treated with the IL-1R antagonist anakinra.

Background Regular physical activity is associated with cardiovascular health; however, intensive exercise can have harmful effects on the heart. Two-dimensional (2D) speckle tracking echocardiography (STE) is a well-established diagnostic tool to evaluate subclinical myocardial dysfunction and has been widely used in athletes in recent years. This study is designed to evaluate whether low-intensity exercise has beneficial effects on myocardial performance. We aimed to evaluate systolic and diastolic functions of myocardium derived from STE in sports practitioners in a low-intensity exercise training program. Method Eighty-four sports practitioners and eighty-two sedentary healthy controls were prospectively included in our study. In addition to standard 2D echocardiographic measurements, left ventricular (LV) global longitudinal strain (GLS), right ventricular (RV) GLS, RV-free wall strain (FWS), left atrium (LA) strain, and strain rate were analyzed. Results Mean LV GLS was significantly higher in sports practitioners compared with sedentary population (-19.21 +/- 2.61% vs -18.37 +/- 2.75%,P = .044). RV GLS was significantly higher in sports practitioners than sedentary population (-21.82 +/- 4.86% vs -20.04 +/- 4.62%,P = .016). Longitudinal strain and strain rate of LA conduit phase were significantly higher in sports practitioners than sedentary participants (-23.60 +/- 6.83% vs -20.20 +/- 6.64%,P = .001; -2.45 +/- 0.81 L/s vs -2.10 +/- 0.89 L/s,P = .010; respectively). Also, LA conduit phase strain/contraction phase strain and conduit phase strain rate/contraction phase strain rate ratios were higher in sports practitioners (1.88 +/- 0.93 vs 1.48 +/- 0.63,P = .001; 1.42 +/- 0.65 vs 1.16 +/- 0.53,P = .005; respectively). Conclusion The findings in the current study suggest that regular low-intensity exercise may have a beneficial effect on both systolic and diastolic functions of the myocardium.

Background: Circulating troponin levels are both stable and higher in patients with end-stage renal disease, even in the absence of acute coronary syndrome. These patients commonly have underlying cardiac problems that frequently cause troponin elevation. The effect of hemodialysis (HD) on troponin levels has not been well elucidated. Thus, investigated herein is the relationship between the changes in troponin levels along with left ventricular deformation and volume depletion in patients with end-stage renal disease. Methods: Patients included were between 18 and 85 years of age and were receiving hemodialysis for at least 6 months. High sensitive cardiac troponin T (hs-cTnT) levels were studied in blood samples taken at the beginning and end of HD. Two-dimensional speckle tracking strain imaging was used to evaluate myocardial contractility. Results: Seventy patients (50.7 ± 16.9 years of age, 27 women) were included in study. The mean volume of ultrafiltration was 3260 ± 990 mL. A significant increase in circulating hs-cTnT levels was observed, as well as a prominent decrease in left ventricular global longitudinal strain (GLS) after HD (52.4 ± 40.2 ng/L vs. 66.8 ± 48.5 ng/L, p < 0.001 and 20.1 ± 3.6% vs. 16.8 ± 3.8% p < 0.001, respectively). Moreover, ultrafiltration rate and GLS were found as the strongest independent variables in relation to the relative increase in hs-cTnT. Conclusions: Hemodialysis can cause a significant increase in hsTnT. This can jeopardize the accuracy of clinical diagnoses based on hs-TnT measurements. GLS may be used as a determinant of this hs-TnT increase. The influence of HD on the cardiovascular system should be kept in mind to prevent unnecessary interventions.

Background The left atrium (LA) is the main contributor of left ventricular (LV) filling. LA volume and volume index are routinely evaluated during echocardiographic assessment as having prognostic value in a wide range of cardiovascular pathologies. Yet, LA volume is easily affected by volume status. Thus, a non-invasive novel parameter such as indices of LA longitudinal strain (LS) have been proposed as alternative measurements. LA strain was shown to be associated with LV filling pressures and it has been suggested to provide prognostic information in patients with heart failure, atrial fibrillation, ischemic and valvular heart diseases. Nevertheless the acute effect of hemodynamic changes on LA LS indices is not well-established due to lack of evidence in healthy subjects and patient populations. The aim of this study is to evaluate the LA mechanics and change in echocardiographic methods used for assessment of LA by examining the end stage kidney patients before and after the hemodialysis (HD). Methods Patients between 18 and 85 years of age, receiving HD for at least 6 months were included. The echocardiographic images were obtained before and after HD. 2D speckle tracking strain analysis was performed for LA in 45 patients. Reference points for analysis are set on the "P" waves. LA reservoir, conduit and contraction phase LS were calculated. The changes in echocardiographic methods before and after hemodialysis were examined. Correlation between volume depletion and change in echocardiographic parameters were calculated. Results 45 patients (47.7 ± 14.7 years of age, 19 women) were included in study. The mean volume of ultrafiltration was 2755.12 ± 845.5 ml . The chamber sizes of LA are decreased after hemodialysis (LA diameter; 4.9 ± 0.8 cm vs. 4.4 ± 0.5 cm p Conclusion LA contraction LS is a volume independent measurement obtained by 2D speckle tracking. Assessment of LA mechanics with echocardiography would be an easy and repeatable assessment which can guide to describe the cardiac pathophysiology and hemodynamics better. Moreover defining novel volume independent parameters for evaluation of LA would contribute to clinical perspectives of the patients.

Objective Ultrafiltration rate is one of the major determinants of adverse outcomes in patients undergoing hemodialysis (HD) therapy. Previous studies have focused on the impact of HD on right ventricular (RV) peak strain values. However, the influence of HD on the temporal characteristics of deformation has not been reported yet. The aim of the present study was to evaluate the impact of high ultrafiltration rate (HUR) on RV mechanical dyssynchrony. Methods Echocardiographic images focused on the RV and left ventricle (LV) were obtained from 60 patients (49.2+-17.3 years, 22 female) before and after HD. Patients were divided into two groups according to ultrafiltration rate. Changes in echocardiographic parameters with HD were examined. Two-dimensional speckle-tracking strain analysis was used to assess deformation. Mechanical dispersion was measured as the standard deviation of time to peak longitudinal strain of six segments for RV and 18 segments for LV. Results The average ultrafiltrated volume and ultrafiltration rate were 3000.1+-1007.9 mL and 11.4+-2.9 mL/kg/h, respectively. Global longitudinal strain (GLS) of the RV and LV decreased after HD in both groups. A significant difference was observed in RV mechanical dispersion with HD for patients in the high ultrafiltration group. A mild statistically insignificant increase in LV mechanical dispersion was also observed after HD. Conclusion HUR has a substantial impact on LV and RV GLS and RV dyssynchrony. Ultrafiltration rates and volumes should be kept as low as possible to achieve hemodynamic stability and tolerability.

Background/aim The aim of this study was to investigate the importance of preprocedural uric acid (UA) level in predicting fractional flow reserve (FFR) results of intermediate coronary lesions in patients with stable coronary artery disease undergoing coronary angiography. Materials and methods We retrospectively analyzed 293 patients who underwent FFR measurement to determine the significance of intermediate coronary stenosis detected by conventional coronary angiography. Patients were divided into 2 groups: Group 1 (n = 127) included patients with FFR of 0.80 (hemodynamically nonsignificant lesions). Uric acid levels were assessed in both groups with the enzymatic colorimetric method by clinical chemistry autoanalyzer. Results The mean UA level was significantly higher in patients whose FFR indicated hemodynamically significant coronary lesions (UA: 5.43 ± 1.29 mg/dL in Group 1 vs. 4.51 ± 1.34 mg/dL in Group 2, P < 0.001). Conclusion Elevated UA levels are associated with hemodynamically significant coronary lesions measured with FFR. Uric acid may be used as a predictor of hemodynamically compromised coronary lesions before FFR procedures.

Background: High-sensitive cardiac troponin (hsTn) levels can be elevated due to non-pathological events such as strenuous exercise. However, the effect of statins on circulating hsTnT levels with moderate exercise is uncertain. Therefore, we evaluated the impact of statins on hsTnT level with moderate exercise. Methods: We enrolled a total of 56 patients: 26 statin users and 30 non-users. All patients were shown to have no coronary artery disease before participating in the study. Participants performed a fixed-protocol moderate level exercise. HsTnT levels were measured before and 4 h after the exercise. Participants were also grouped based on their hsTnT levels, as proposed in the recent European Society of Cardiology guideline (0-1 hour algorithm) for acute coronary syndromes without persistent ST-segment elevation. Results: Statin users showed a significant increase in serum hsTnT levels with moderate exercise (p = .004), whereas the control group showed a modest increase without statistical significance (p = .664). The percentage of patients whose hsTnT levels exceeded the rule-out limits for non-ST-segment myocardial infarction diagnosis (according to the 0-1 algorithm) after moderate exercise varied significantly between groups (p = .024). Conclusions: Statin therapy can cause a significant increase in hsTnT levels after moderate exercise. This increase can jeopardise the accuracy of clinical diagnoses based on the newly implemented algorithms. The awareness of these adverse effects of statins, mainly used by patients with high risk of coronary events, can prevent misdiagnosis or unnecessary hospitalisations.

Background Vitamin D is known for its effect in calcium and bone homeostasis. There is an increasing evidence for health benefits accomplished by activated vitamin D that go beyond these classical functions. Previous studies have suggested that lower vitamin D levels are associated with increased cardiovascular disease risk. Therefore, we aimed to evaluate relationship between vitamin D levels and extent and severity of coronary artery disease. Materials and methods A total of 746 patients in whom coronary angiography was performed between August 2012 and July 2013 were enrolled in this study. Serum vitamin D levels were measured, and patients were grouped according to their serum vitamin D levels (vitamin D 20 ng/dL (n = 144) Group 2). Gensini score system was used to evaluate the association between serum vitamin D levels and severity and extent of coronary artery disease. Results There was no significant difference between the groups in terms of baseline characteristics and demographic characteristics. Mean serum vitamin D levels of all patient cohort was 15·54 ± 7·46 ng/mL. Group 1 and Group 2 had an average serum vitamin D levels of 12·6 ± 3·3 ng/mL and 27·5 ± 7·8 ng/mL, respectively. Gensini score for all cohort was 26·25 ± 34·32. Group 1 had an average Gensini score of 26·4 ± 35·7; on the other hand, Gensini score was 25·5 ± 27·5 in Group 2 (P = 0·097). Conclusions This study failed to demonstrate significant relationship between serum vitamin D levels and the severity and extent of coronary artery disease. Further studies with more participation and homogenous groups with comparable individual and environmental features are needed to evaluate the association of serum vitamin D levels and cardiovascular diseases.

Giriş: Kan dolaşımında bulunan monosit sayısı yeni aterosklerotik plak oluşumundaöngörücüdür. Bununla birlikte yüksek dansiteli lipoprotein kolesterol (HDL)düzeyleri ile ateroskleroz arasında güçlü bir negatif ilişki vardır. Buçalışmada, monosit sayısı/HDL oranıyla koroner arter hastalığı ciddiyetiarasındaki ilişkiyi değerlendirmeyi amaçladık.Hastalar veYöntem: Koroner anjiyografi yapılan toplam 760 hasta çalışmayadahil edildi. Koroner ateroskleroz ciddiyeti Gensini skorlama sistemikullanılarak değerlendirildi ve hastalar Gensini skorlarına göre yüksek (>20) ve düşük (< 20) olarak iki gruba ayrıldı. Bazal karakteristik özelliklerve laboratuvar parametreleri kaydedilerek yüksek ve düşük Gensini skoru olanhastalar arasında karşılaştırıldı.Bulgular: Hipertansiyon, diabetes mellitus, hiperlipidemi, ileri yaş ve sigaraiçiciliği yüksek Gensini skoru olan hastalarda daha fazlaydı. Açlık kan şekeri,kreatinin düzeyleri ve monosit/HDL oranı düşük Gensini skoru olan hastalardayüksek Gensini skoru olanlara kıyasla daha düşüktü. Lojistik regresyonanalizinde ileri yaş, açlık kan şekeri, hiperlipidemi, aile öyküsü ve erkekcinsiyetin yüksek Gensini skoru için bağımsız parametreler olduğu gözlendi.Monosit/HDL oranının, Gensini skoruyla korele olduğu (p< 0.001) ancak bukorelasyonun çok zayıf olduğu tespit edildi (Spearman’s Rho: 0.159).Sonuç: Monosit/HDL oranı ile Gensini skoruyla eldeedilen ateroskleroz yaygınlığı arasında zayıf da olsa bir ilişki izlenmiştir.Ancak Monosit/HDL oranı ve aterosklerotik kalp hastalığı arasındaki ilişkiyibelirlemek için daha fazla klinik çalışmaya ihtiyaç vardır., Introduction:Circulatingmonocyte count is predictive of new atherosclerotic plaque development. Inaddition, there is a strong inverse relationship between high-densitylipoprotein (HDL) cholesterol and atherosclerosis. We aimed to investigate therelationship between the monocyte/HDL cholesterol ratio and severity ofcoronary artery disease.Patientsand Methods: A total of 760 patients who underwent coronaryangiography were included in the study. The severity of coronaryatherosclerosis was calculated by the Gensini score, and the patients weregrouped as having low (< 20) and high (> 20) Gensini scores. Baselinecharacteristics and laboratory parameters were recorded and compared betweenpatients with low and high Gensini scores. Results: Hypertension,diabetes mellitus, hyperlipidaemia, advanced age and smoking were more commonin patients with a high Gensini score. Fasting blood glucose levels, creatininelevels and monocyte/HDL cholesterol ratio were significantly lower in patientswith a low Gensini score than in those with a high Gensini score. Logisticregression analysis revealed that older age, fasting blood glucose levels,hyperlipidaemia, family history of coronary artery disease and male gender wereindependent predictors of a high Gensini score. We observed a correlationbetween the monocyte/HDL cholesterol ratio and Gensini score (p< 0.001).However, this correlation was weak (Spearman’s rho = 0.159).Conclusion: We observed a positive but weak correlationbetween the monocyte/HDL cholesterol; ratio and increased coronaryatherosclerotic burden, as calculated by Gensini scoring. Further studies arerequired to demonstrate the relationship between the monocyte/HDL cholesterolratio and atherosclerotic cardiovascular disease.

Objective Previous studies have suggested that there is a relationship between coronary artery disease (CAD) and parathyroid hormone (PTH) levels. Here, we aimed to evaluate the association between PTH levels and severity of CAD. Methods Patients were divided into two groups based on their serum PTH values. Patients with PTH levels ≤72 pg/mL were accepted as Group 1 (n=568) and >72 pg/mL as Group 2 (n=87). Gensini score system and >50% stenosis in any coronary artery with conventional coronary angiography were used to determine the extensiveness of CAD. This study was designed as a prospective and cross-sectional study. Results Baseline characteristics except for age, gender, and blood pressure were similar between groups. Mean serum PTH levels of the entire cohort was 43.4±29.5 pg/mL. Median Gensini score was 19.5 in Group 1 and 14.5 in Group 2 (p=0.75). On the other hand, PTH levels were weakly correlated with Gensini score (Spearman's Rho=0.11, p=0.003). Additionally, we did not observe a statistically significant difference between PTH levels and the number of stenotic vessels (p=0.14). This study was designed as a prospective and cross-sectional study. Conclusion There is no association between serum PTH levels and extensiveness of CAD.

Coronary artery anomalies are rare and mostly silent in clinical practice. First manifestation of this congenital abnormality can be devastating as syncope, acute coronary syndrome, and sudden cardiac death. Herein we report a case with coronary artery anomaly complicated with ST segment myocardial infarction in both inferior and anterior walls simultaneously diagnosed during primary percutaneous coronary intervention.

Background Device closure of atrial septal defect (ASD) and patent foramen ovale (PFO) are both associated with short- and long-term complications. Our knowledge of the complication rates of ASD and PFO closure is limited. Our objective was to review the peri-procedural and long-term complications of ASD and PFO closure. Methods Medline, EMBASE, and Scopus databases were searched between 1973 and 2012. A total of 28,142 patients from 203 case series were included. Of these 203 articles, 111 were reporting ASD closure, 61 were reporting PFO closure, and 31 were reporting both. Pooled incidence rates of cardiac complications were calculated separately for peri-procedural and at follow-up. Results Peri-procedural major complications were reported from 0% to 9.4%, with a pooled estimate rate of 1.4% (95% CI: 1.3–1.6%). It was 1.6% (95% CI: 1.4–1.8%) in ASD group, 1.1% (95% CI: 0.9–1.3%) in PFO group, and 1.3% (95% CI: 0.9–1.9%) in ASD/PFO group. The most common major complication was the device embolization requiring surgery. Peri-procedural minor complications were reported with a pooled estimate rate of 1.4% (95% CI: 1.2–1.7%). It was 1.6% (95% CI: 1.2–2.1%) in ASD group, 1.3% (95% CI: 1.0–1.7%) in PFO group, and 1.5% (95% CI: 1.1–1.2.1%) in ASD/PFO group. The most frequent major complications at follow-up were cerebrovascular events [1.3% (95% CI: 1.1–1.6%)] and device thrombosis [1.2% (95% CI: 1.0–1.4%)]. Both were more frequent in PFO group. Conclusion Device closure of ASD and PFO are associated with non-negligible serious complications, both in early and long-term. © 2013 Wiley Periodicals, Inc.

Son yıllardaki teknik gelişmeler nedeniyle kardiyovasküler hastalıkların tanısında bilgisayarlı tomografinin yeri gün geçtikçe artmaktadır. Ancak bu işlem sırasında kullanılan radyasyon dozu, buna bağlı oluşabilecek potansiyel sonuçlar konusunda tartışma yaratmaktadır. Elimizde henüz bilgisayarlı tomografide kullanılan radyasyon dozunun yol açabileceği istenmeyen etkiler konusunda net veriler bulunmamaktadır. Bu derlemede bilgisayarlı tomografi ve radyasyon riski ile ilgili literatürdeki veriler gözden geçirilmiştir. Bilgisayarlı tomografide kullanılan radyasyon dozunu azaltmak için alınabilecek önlemlerin başında testin doğru endikasyonla, uygun hastada yapılması gelmektedir. Bunun yanında son yıllarda geliştirilen radyasyon azaltıcı teknolojiler ve kişiye özgü çekim teknikleri sayesinde kullanılan radyasyon dozu belirgin ölçüde azaltılabilmektedir. Klinisyenlerin radyasyon riskinin azaltılması açısından kullanılması gereken teknikler konusunda bilgi sahibi olmaları ve çalıştıkları merkezdeki teknik olanakların farkında olmaları önem taşımaktadır.With the recent technological developments, computed tomography is becoming more important in the diagnosis of cardiovascular diseases. However, potential complications of the radiation dose used during the test have led debates. In the current situation, the data about undesirable effects of radiation dose used in cardiac computed tomography is not clear. In this paper, we reviewed the data about computed tomography and the risk of radiation. In order to reduce the risk of radiation due to computed tomography, the test should be performed with proper indication and in suitable patients. Besides, recently developed radiation dose reduction technologies and patient specific protocols have significantly reduced the radiation exposure. The clinicians should be well informed about the radiation reduction techniques and aware of the technical capabilities in their hospital.

Background and Objectives: Genetic predisposition is an important risk factor for coronary artery disease (CAD). In this study, we aimed to evaluate the impact of rs10757274 and rs2383206 polymorphisms in chromosome 9p21 on presence and severity of CAD in a Turkish population. Subjects and Methods: A total of 646 patients who underwent coronary angiography were included in this study. Coronary vessel score and Gensini score were calculated to assess the angiographic severity of CAD. Alleles of AA, AG, and GG were determined for rs10757274 (polymorphism-1) and rs2383206 (polymorphism-2) polymorphisms located in chromosome 9p21 from the blood samples. Results: There was a significant difference between the alleles in polymorphism-1 in the presence of coronary artery disease (38.9% in AA, 48.0% in GG and 56.4% in AG, p=0.017). However, there was no difference between the alleles in polymorphism-2. According to vessel scores, there was a significant difference between the alleles in polymorphism-1 (AA 0.71 +/- 1.04, GG 0.88 +/- 1.07, AG 1.06 +/- 1.12, p=0.018). In polymorphism-2, vessel scores did not show a difference between the alleles. In polymorphism-1, there was a significant difference in Gensini score (p=0.041). Gensini scores did not differ between the alleles in polymorphism-2 (p>0.05 for all). In multivariate analyses, none of the alleles was an independent factor for presence of CAD. Conclusion: The presence of rs10757274 polymorphism including AG allele in chromosome 9p21 was related to CAD. However, this relationship was not independent of other cardiovascular risk factors.

A B S T R A C T S the leading disease, follow by arrhythmia, then congestive heart failure. Congestive heart failure was diagnosed in 19,6% cases. Congenital heart diseases was diagnosed in 5,9% of studied population. The most diagnosed pathology was isolated ventricular septal defect and tetralogy of Fallot. Post-rheumatic valvulopathies and congenital heart diseases are the first aetiological factor of congestive heart failure in young. Results: Patients with severe hypertension, congestive heart failure, symptomatic arrhythmias were admitted for more investigations and proper care. After the compensation drug treatment, patient needed surgery, underwent surgical procedure. The hospital mortality rate was 0,2%. The poor compliance and limited finances gives the follow-up difficult. Conclusion: This study confirms that rheumatic heart disease still accounts for a major proportion of all cardiovascular diseases in children and young adults in African countries. Rapid urbanization and transition from agrarian life to the wage-earning economy of city life continue to fuel increases in average blood pressure levels and prevalence of hypertension.
