This article discusses the long-term follow-up of a surgical procedure called the UFO-procedure, which is used to treat severe concomitant aortic and mitral valve endocarditis. The procedure involves the resection of the affected valves and the intervalvular fibrous body, followed by reconstruction using a double patch technique. The study analyzed data from 41 patients who underwent the UFO-procedure and found that the procedure was technically successful in all patients, although half of them died in the hospital due to sepsis and multi-organ failure. However, surviving patients reported a good quality of life. The article concludes that the UFO procedure can provide a meaningful perspective for patients with severe endocarditis, but classic risk scores do not accurately predict outcomes for this specific patient population.

This article, published in the journal Thoracic & Cardiovascular Surgeon, examines the long-term survival rates of elderly patients who undergo coronary artery bypass grafting (CABG) compared to the general population. The study found that elderly patients who undergo CABG have a significantly lower risk of death compared to their age-matched counterparts in the general population. This survival advantage becomes apparent after the first year following surgery and highlights the life-prolonging effect of bypass surgery in elderly patients. The findings suggest that CABG may help eliminate the expected reduction in life expectancy due to coronary artery disease. [Extracted from the article]

This article, titled "Mini-sternotomy versus Right Anterior Mini-thoracotomy for Surgical Aortic Valve Replacement¿A Systematic Review and Meta-analysis," compares the clinical outcomes of two minimally invasive techniques for aortic valve replacement (AVR): mini-sternotomy (MS) and right anterior mini-thoracotomy (RAM-T). The study reviewed ten studies with a total of 30,524 patients and found that there was no significant difference in perioperative mortality between the two approaches. However, RAM-T was associated with higher rates of reoperation for bleeding, lower rates of stroke, and longer operation duration compared to MS. Other secondary endpoints did not show statistically significant differences. [Extracted from the article]

This article, titled "Permanent Pacemaker Requirements after Tricuspid Valve Surgery¿A Comprehensive Single Center Experience," discusses the requirement for permanent pacemaker (PPM) implantation after tricuspid valve (TV) surgery. The study analyzed data from a single center and found that the introduction of a standard operating procedure (SOP) for addressing the TV resulted in a decrease in PPM requirements. The study also found that surgical experience may play a role in the need for PPM. Overall, the article suggests that TV surgery can be performed with low rates of PPM and that the use of an SOP may further reduce the need for PPM. [Extracted from the article]

This article discusses the potential benefits of avoiding cardiopulmonary bypass during coronary artery bypass grafting (Off-Pump CABG) in patients with signs of early liver fibrosis. The study utilized the Fib-4 score, which assesses liver fibrosis based on ALT, AST, platelet count, and patient age, to compare the outcomes of Off-Pump and On-Pump CABG surgeries. The results showed that Off-Pump CABG had lower mortality rates compared to On-Pump CABG in patients with a Fib-4 score above 1.2, and this difference in mortality increased with higher Fib-4 scores. The study suggests that Off-Pump CABG may be superior in patients with early liver fibrosis, and the Fib-4 score is a valuable tool for assessing cardiac surgical risk. [Extracted from the article]

A meta-analysis was conducted to compare the outcomes of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients with chronic total occlusion (CTO). The analysis included seven studies with a total of 14,196 patients. The results showed that CABG was associated with a lower risk of long-term mortality, as well as lower rates of long-term myocardial infarction (MI) and repeat revascularization compared to PCI. However, there were no significant differences in other secondary endpoints. The findings suggest that CABG may be a superior treatment option for patients with CTO. [Extracted from the article]

The administration of crushed or chewed P2Y12 inhibitors (P2Y12i) allows faster platelet inhibition in patients presenting acute coronary syndrome (ACS). Whether this administration approach is safe needs further analysis. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing chewed/crushed to integral P2Y12i administration in patients with ACS. Major bleeding, minor bleeding, and major adverse cardiovascular events (MACE) were analyzed as binary outcomes. Platelet reactivity unit (PRU) was assessed as a continuous outcome to estimate the impact on platelet physiology. A subgroup analysis of P2Y12i administered was performed. Nine studies comprising 1091 patients with ACS were included, 77% were males. Overall, 87% presented with ST-segment elevation acute myocardial infarction. Six studies administered Ticagrelor, while 3 studies used Prasugrel. The absolute risk of bleeding, assessed by TIMI, was low in both intervention and control arms (0.36% vs. 0.95% for major bleedings and 3.3% vs. 4.4% for minor bleedings), and crushed/chewed administration did not increase the relative risk of bleeding events for TIMI major or minor bleedings (RR 0.51, 95% CI 0.09-2.77, p = 0.293; RR 0.76, 95% CI 0.24-2.43, p = 0.542) or MACE (RR 0.94, 95% CI 0.28-3.19, p = 0.902). PRU was significantly reduced within 1 h after administration in the crushed/chewed P2Y12i group (MD: -70.0%, 95% CI, -89.0 to -51.1%, p<0.01) while we did not observe a significant difference after 4 h (MD: -15.1%, 95% CI -34.2 to 4.0%, p = 0.12). The type of drug did not influence the relative risk of crushed/chewed P2Y12i on major or minor bleeding (p interaction = 0.62 and p interaction = 0.23 , respectively). The crushed/chewed administration of P2Y12i in the setting of ACS was not associated with an increased risk of bleeding, suggesting the safety of this strategy., Competing Interests: Declarations.

This study aimed to conduct a systematic review and meta-analysis comparing video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT) in the context of pulmonary metastasectomy. Three databases were assessed. The primary outcome was overall survival. The secondary outcomes were recurrence-free survival, ipsilateral recurrence, and hospital length of stay (LOS). Hazard ratios (HRs), odds ratios (ORs), and mean difference (MD) with 95% confidence intervals (CIs) were calculated. Reconstruction of time-to-event data and sensitivity analyses were performed for the primary endpoint. After screening, 11 studies were included encompassing 2159 patients undergoing lung metastasectomy (VATS: 827; OT: 1332). Compared to OT, patients who underwent VATS had higher overall survival rates (HR 0.75; 95% CI 0.67-0.85; p < 0.01), no significant difference in recurrence-free survival (HR 1.07; 95% CI 0.88-1.29; p = 0.48), shorter hospital LOS (MD -1.99 days; 95% CI -2.59 to -1.39; p < 0.01), and no significant difference in ipsilateral recurrence rates (OR 0.86; 95% CI 0.52-1.42; p = 0.56). For patients undergoing pulmonary metastasectomy, VATS strategy is associated with higher survival rates and reduced hospital LOS when compared with OT. Moreover, metastasis recurrence does not seem to be associated with long-term mortality in this population., (© 2024 The Author(s). Thoracic Cancer published by John Wiley & Sons Australia, Ltd.)

Background:  Rapid and accurate diagnosis of infective endocarditis (IE) allows timely management of this life-threatening disease and improves outcome. The Duke criteria have traditionally been the clinical method for diagnosing IE. These criteria were reformulated at different timepoints. We aimed to evaluate the real accuracy of the modified Duke criteria based on several studies that concluded the diagnosis of IE., Methods:  Three databases were assessed. Studies were considered for inclusion if they reported the use of modified Duke criteria as the initial approach and the confirmation of the diagnosis with the gold standard methods. The meta-analysis of diagnostic test accuracy was performed after fitting the hierarchical summary receiver operating characteristic model (HSROC) with bivariate model and displaying the summarized measures of sensitivity and specificity, and positive and negative likelihood ratios., Results:  A total of 11 studies were included. Accuracy in the included studies ranged from 62.3 to 92.2%, sensitivity ranged from 58.3 to 84.0%, and specificity ranged from 50.0 to 100%. The combined overall sensitivity and specificity were 85% (95% CI: 0.77-0.90) and 98% (95% CI: 0.89-0.99), respectively. The positive likelihood ratio was 40.2 (95% CI: 7.26-220.74) and the negative likelihood ratio was 0.15 (95% CI: 0.01-0.23)., Conclusion:  The analysis reveals that the modified Duke criteria have a high positive likelihood ratio, suggesting a robust correlation between a positive test result and the existence of IE, and a very good overall specificity at 98%. The latter aspect holds significant importance in order to prevent unnecessary overtreatment, given the intricacies involved in managing IE., Competing Interests: None declared., (Thieme.

Objectives: The study aimed to review a multicentre experience of patients undergoing surgical intervention for infective endocarditis caused by Cutibacterium acnes and to analyse the diagnostic challenges and operative results., Methods: We retrospectively reviewed 8812 patients undergoing cardiac surgery for endocarditis at 12 cardiac surgical departments across Germany. The overall population was divided based on the type of endocarditis (i.e. native and prosthetic valve endocarditis). Primary outcomes were in-hospital mortality, 1- and 5-year survival., Results: Cutibacterium acnes caused endocarditis in 269 patients (3.1%). Median age was 65 years (54-72 years) and 237 (88.1%) were male. We observed significantly higher rates of native valve endocarditis in patients aged 21-40, whereas prosthetic valve endocarditis was more frequent in all other age groups (P < 0.001). The median EuroSCORE II of the cohort was 10.7 (5.0-29.6), with it being significantly higher in the prosthetic valve endocarditis group (P < 0.001). Blood culture-negative infective endocarditis was initially reported in 54.3% of the patients. The in-hospital mortality was comparable between the groups (P = 0.340). Survival at 1 and 5 years was significantly higher in the native valve endocarditis group (P < 0.001)., Conclusions: Cutibacterium acnes causes native valve endocarditis, especially in younger patients. The incidence of endocarditis caused by C.acnes is alarming and is at par with well-known endocarditis pathogens such as the HACEK group. The pathogen has a low virulence and presents with a rather indolent course. The diagnosis of C.acnes endocarditis is challenging and requires a multimodal specialized approach. Surgical treatment is associated with acceptable outcomes., (© The Author(s) 2024. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

Recent randomized evidence has shown that low-dose colchicine lowers the risk of cardiovascular events in patients with chronic coronary artery disease. Colchicine has also been used in coronary artery bypass grafting (CABG), with individual studies suggesting protective effects for postoperative atrial fibrillation (POAF). We performed a meta-analysis of studies assessing the effect of colchicine on outcomes in CABG surgery. We systematically searched 3 libraries (MEDLINE, Web of Science, and the Cochrane Library), selecting all randomized control trials including patients who underwent CABG and were randomized for perioperative administration of colchicine versus standard of care. The primary outcome was incidence of POAF. The inverse variance method (DerSimonian&Laird) and random-effects model were performed. The leave-one-out analysis was carried out as a sensitivity analysis to address possible outliers. From 205 screened studies, 5 met the inclusion criteria and were selected. The data from 839 patients were included in the final analysis. The included studies were published between 2014 and 2022. The perioperative administration of colchicine was associated with the reduction of POAF rates after CABG compared with standard of care (relative risk 0.54, 95% confidence interval 0.40 to 0.73, p <0.01). The leave-one-out analysis confirmed the robustness of the analysis, with minimal variations of the confidence interval. This meta-analysis of randomized studies suggests that the perioperative administration of colchicine is associated with significant reduction of POAF after CABG., Competing Interests: Declaration of competing interest Dr. Caldonazo received funding from the Deutsche Forschungsgemeinschaft (German Research Foundation) Clinician Scientist Program OrganAge funding number 413668513, by the Deutsche Herzstiftung (German Heart Foundation) funding number S/03/23 and by the Interdisciplinary Center of Clinical Research of the Medical Faculty Jena., (Copyright © 2024 The Author(s).

Coronary computed tomography angiography (CCTA) has emerged as a noninvasive alternative to invasive coronary angiography (ICA) for diagnosing coronary artery disease (CAD). Hence, the question of CCTA's ability to guide surgical decision-making moves into the center of attention. CCTA is specifically powerful in ruling out CAD. We, therefore, performed a meta-analysis and systematic review to compare the clinical end points between patients who received ICA or CCTA to rule out CAD before valve surgery. A total of 3 databases were assessed. The primary outcome was perioperative mortality. Secondary outcomes were acute kidney injury (AKI), myocardial infarction (MI), stroke, and major adverse cardiovascular events (MACEs). The odds ratio (OR) and the respective confidence interval (CI) was calculated. A random-effects model was performed. A total of 5 studies with 6,654 patients qualified for the analysis. There was no significant difference between the 2 groups regarding the primary end point (OR 1.20, 95% CI 0.67 to 2.15, p = 0.53). The secondary outcomes also did not show any significant differences in AKI (OR 1.14, 95% CI 1.14, 0.88 to 1.49, p = 0.32), MI (OR 0.89, 95% CI 0.65 to 1.22, p = 0.45), stroke (OR 1.12, 95% CI 0.48 to 2.60, p = 0.79), or MACEs (OR 1.17, 95% CI 0.86 to 1.59, p = 0.33) incidences. The analysis suggests that CCTA is a safe and reliable noninvasive alternative to ICA for coronary imaging before valve surgery. Conceivable differences in imaging modalities were not associated with increases in perioperative mortality, AKI, MI, stroke, or MACEs., Competing Interests: Declaration of competing interest The authors have no competing interests to declare., (Copyright © 2024 The Author(s).

Background: Aortic regurgitation (AR) is a known complication after left ventricular assist device (LVAD) implantation potentially leading to recurrent heart failure. Possible pathomechanisms include valvular pathologies and aortic root dilatation. We assessed aortic root dimensions in a group of consecutive LVAD patients who received HeartMate 3., Methods: Since 11/2015, we identified 68 patients with no or mild AR at the time of HeartMate 3 implantation who underwent serial echocardiography to assess AR and aortic root dimensions (annulus, sinus, and sinotubular junction). Median follow-up was 40 months (2-94 months). Results were correlated with clinical outcomes., Results: Patients were 60 ± 10 years old, predominantly male (88%) and 35% presented in preoperative critical condition as defined by INTERMACS levels 1 and 2. During follow-up, 23 patients developed AR ≥ II (34%). Actuarial incidence was 8% at 1 year, 29% at 3 years and 41% at 5 years. Echocardiography revealed practically stable root dimensions at the latest follow-up compared to the preoperative state (annulus: 23 ± 3 mm vs. 23 ± 2 mm, sinus: 32 ± 4 mm vs. 33 ± 3 mm, sinotubular junction: 27 ± 3 mm vs. 28 ± 3 mm), irrespective of the development of AR. Serial CT angiograms were performed in 13 patients to confirm echocardiographic findings. Twenty-one patients died during LVAD support leading to a 5-year survival of 71%, showing no difference between patients with and without AR ≥ II (p = 0.573)., Conclusions: At least moderate AR develops over time in a substantial fraction of patients (one-third over 3 years). The mechanism does not seem to be related to dilatation of the aortic annulus or root., (© 2024 International Center for Artificial Organ and Transplantation (ICAOT) and Wiley Periodicals LLC.)

Background: Transcatheter Aortic Valve Implantation (TAVI) and Surgical Aortic Valve Replacement (SAVR) have different levels of invasiveness which can result in different levels of functional status after the procedure., Methods: We performed a systematic review and meta-analysis to detect studies showing direct comparison between TAVI and SAVR regarding postoperative functional status. The primary endpoint was the incidence of postoperative delirium (POD) after TAVI or SAVR, assessed using the Confusion Assessment Method (CAM). Secondary endpoints included 30-day mortality, stroke, major bleeding, and hospital length of stay (LOS)., Results: We identified 1,161 manuscripts, of which 10 studies (12,015 patients) were analyzed. TAVI patients had a significantly lower incidence of POD (OR: 0.35, 95 % CI, 0.26-0.48, p < 0.01) compared to SAVR patients. No significant differences were found in secondary outcomes between the groups., Conclusions: TAVI is associated with a lower incidence of postoperative delirium compared to SAVR without compromising length of stay or other major clinical outcomes. Further research is needed to understand the impact of postoperative delirium on short and long-term outcomes., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Background: The impact of air bubbles into the cerebral circulation after open heart surgery has been a topic of discussion since the introduction of the heart-lung machine. The aim of the study was to evaluate whether the use of a dedicated commercial sponge diffuser is better than a custom-made narrow section cannula or the absence of CO2 in preventing neurological events after aortic valve replacement via J mini-sternotomy., Methods: Three cohorts of J-shaped mini-sternotomy performed at three different centers were prospectively compared: CO2 supplied via sponge diffuser, CO2 supplied via cannula, and no CO2 supply. Propensity matching was used to obtain comparable groups. The primary endpoints were postoperative stroke, transitory ischemic attack, convulsions, and dizziness. Secondary endpoints were 30-day mortality, duration of mechanical ventilation, and intensive care unit length of stay., Results: 275 patients were enrolled in the study. After propensity matching, the sponge diffuser cohort had a significantly lower duration of mechanical ventilation (P < 0.001) and 30-day mortality (P = 0.05) when compared to the cannula cohort and the no-CO2 cohort, a lower incidence of all neurological events (P = 0.03) and dizziness (P = 0.05) when compare to the no-CO2 cohort, and a lower intensive care unit length of stay when compared to the cannula cohort (P = 0.001)., Conclusions: The sponge diffuser used to deliver the CO2 into the surgical field during aortic valve replacement via J mini-sternotomy has been demonstrated to guarantee better neurological outcomes compared to a custom-made narrow section cannula or the absence of CO2., (© 2024.

Background: Liver dysfunction is a known risk factor in the cardiovascular field. It specifically increases perioperative risk in patients undergoing coronary bypass surgery. Since percutaneous coronary intervention (PCI) is the much less invasive procedure for the treatment of coronary artery disease, we aimed to assess the relationship of liver dysfunction with outcomes in patients undergoing PCI., Methods: Three libraries were searched (MEDLINE, Web of Science and The Cochrane Library). We performed a meta-analysis of all studies in patients who underwent PCI that provided information on the presence or absence of liver dysfunction. Primary outcome was short-term mortality. Secondary outcomes were major adverse cardio- and cerebrovascular events (MACCE), bleeding and acute kidney injury. Random-effects model was applied., Results: Five studies were selected and the data from 10,710,317 patients were included in the final analysis. In comparison with the absence of liver dysfunction, patients with liver dysfunction were associated with higher short-term mortality (OR 2.97, 95%CI 1.23-7.18, p = 0.02), higher MACCE (OR 1.42, 95%CI 1.08-1.87, p = 0.01), and higher bleeding (OR 2.23, 95%CI 1.65-3.00, p < 0.01). There was no significant difference regarding acute kidney injury (OR 1.20, 95%CI 0.50-2.87, p = 0.69)., Conclusions: The analysis suggests that liver dysfunction in patients undergoing PCI is independently associated with higher risk of short-term mortality and increased occurrence of MACCE and bleeding. However, there appears to be no association to acute kidney injury., (© 2024. The Author(s).)

Background: Patients undergoing high-risk surgeries with acid-based disorders are associated with poor outcomes. The screening of mixed acid-based metabolic disorders by calculating delta anion gap (AG)/delta bicarbonate (Bic) has a clinically relevant role in patients with high AG metabolic acidosis (MA), however its utility in individuals facing high-risk surgical procedures remains unclear., Objective: Characterize metabolic acidosis using delta-AG/delta-Bic and its associations in patients undergoing high-risk surgeries with possible outcome-related complications., Design: Prospective observational multicentric study., Setting: Three tertiary hospitals in Brazil., Patients: Patients undergoing high-risk surgeries, aged 18 years or older, requiring postoperative critical care., Main Outcome Measures: Patients undergoing high-risk surgeries monitored during the postoperative phase across three distinct intensive care units (ICUs), with assessment encompassing laboratory analyses upon admission and 24 h thereafter. Patients with MA and with elevated AG within 24 h were separated into 3 subgroups: [G1 - delta-AG/delta-Bic < 1.0] MA associated with hyperchloremia; [G2 - delta-AG/delta-Bic between 1.0 and 1.6] MA and no mixed disorders; and [G3 - delta-AG/delta-Bic > 1.6] MA associated with alkalosis. Primary endpoint was 30-day mortality. The secondary endpoints were cardiovascular, respiratory, renal, neurological, coagulation and infective complications., Results: From the 621 surgical patients admitted to ICU, 421 (51.7%) had any type of acidosis. After 24 h, 140 patients remained with MA with elevated AG (G1: 101, G2: 18, and G3: 21). When compared to patients from subgroups 1 and 3, the subgroup with no mixed disorders 2 showed higher 30-day mortality (adjusted HR = 3.72; 95% CI 1.11-12.89, p = 0.001), cardiovascular complications (p = 0.001), ICU mortality (p = 0.03) and sum of all complications during the ICU period (p = 0.021)., Conclusion: In the postoperative time, patients with metabolic acidosis and no mixed disorders present higher ICU-Mortality and higher cardiovascular postoperative complications when compared with patients with combined hyperchloremia or alkalosis. Delta-AG/delta-Bic can be a useful tool to evaluate major clinical outcomes in this population., (© 2024. The Author(s).)

Age is an independent risk factor for mortality even when all known comorbidities are considered. Thus, other factors may additionally contribute to the age-associated risk. We performed a systematic literature search and identified 161 manuscripts, of which 32 studies (18,256 patients) were analyzed. Cross-clamp time correlated with observed mortality. The increase in mortality risk with cross-clamp time was much greater in older patients than in younger patients. The log odds ratio (OR) for age and cross-clamp time was 0.07 and 0.01, respectively, which was highly significant for both independent risk factors. Age accelerates the increase in mortality risk with increasing aortic cross-clamp times., Competing Interests: None declared., (Thieme. All rights reserved.)

Background: Complete removal of cardiac implantable electronic devices (CIEDs) is recommended in patients with CIED infections, including both systemic and localized pocket infection. The aim of the study was to provide an up-to-date and comprehensive assessment of evidence relating to the effect of complete CIED extraction in patients with a CIED infection., Methods: We performed a systematic review and meta-analysis of studies reporting short- and mid-term outcomes in patients who had a device infection or infective endocarditis (IE) and underwent complete removal of the cardiac device (generator and leads) compared to those who received conservative therapy (no removal, partial removal, local antibiotic infiltration or isolated antibiotic therapy). The primary outcome was reinfection/relapse. Secondary outcomes were short-term (30-day/in-hospital) and mid-term (mean follow-up: 43.0 months) mortality. Random effects model was performed., Results: Thirty-two studies met the criteria for inclusion in the final analysis. Patients with complete CIED extraction (n = 905) exhibited a lower rate of relapse/re-infection compared to patients (n = 195) with a conservative treatment approach (n = 195, OR 0.02, 95%CI 0.01-0.06, p < 0.0001, mean-follow-up: 16.1 months). Additionally, these patients displayed a lower short- (OR 0.40, 95%CI 0.23-0.69, p = 0.01) and mid-term (OR 0.52, 95%CI 0.34-0.78, p = 0.002) mortality., Conclusions: The analysis indicates that patients with a CIED infection who undergo complete CIED extraction exhibit a lower rate of relapse/re-infection. Additionally, a lower short- and mid-term mortality is observed, although it is acknowledged that this outcome may be influenced by treatment allocation bias., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

The degree of both mitral (MR) and tricuspid valve regurgitation (TR) correlates with mortality. A vicious cycle has been proposed consisting of increasing regurgitation and decreasing ventricular function. Restoration of valve competence should break this vicious cycle and improve life expectancy. However, a "pop-off" mechanism keeps being entertained, presumably allowing poorly pumping ventricles to relieve volume into the low-pressure atrium through an incomplete repair, avoiding pump failure. We reasoned that if such a mechanism exists, it should offset the relationship between mortality and valve regurgitation after an invasive procedure. In this context, we meta-analytically compared valve regurgitation degree and survival before or after atrio-ventricular valve treatment. The results show significant relationships between valve regurgitation and mortality under all conditions (i.e., before and after surgery or intervention) and irrespective of the underlying pathology (i.e., functional or structural). In summary, the ubiquitously present relationship between valve regurgitation and mortality suggests that generating a tight and durable repair of the affected valve is key to long-term exploitation of a symptom-reducing and life-prologing mechanism, independent of the underlying valve pathology. This recognition may explain current controversies in the treatment effects of MR and TR., Competing Interests: None declared., (Thieme. All rights reserved.)

Background: Postoperative bleeding requiring re-exploration is a serious complication that occurs in 2.8-4.6% of patients undergoing cardiac surgery. Re-exploration has previously been associated with a higher risk of short-term mortality. However, a comprehensive analysis of long-term outcomes after re-exploration for bleeding has not been published., Materials and Methods: The authors performed a systematic, three databases search to identify studies reporting long-term outcomes in patients who required re-exploration for bleeding after cardiac surgery compared to patients who did not, with at least 1-year of follow-up. Long-term survival was the primary outcome. Secondary outcomes were operative mortality, myocardial infarction, stroke, renal and respiratory complications, and hospital length of stay. Random-effects models was used. Individual patient survival data was extracted from available survival curves and reconstructed using restricted mean survival time., Results: Six studies totaling 135 456 patients were included. The average follow-up was 5.5 years. In the individual patient data, patients who required re-exploration had a significantly higher risk of death compared with patients who did not [hazard ratio (HR): 1.21; 95% CI: 1.14-1.27; P <0.001], which was confirmed by the study-level survival analysis (HR: 1.32; 95% CI: 1.12-1.56; P <0.01). Re-exploration was also associated with a higher risk of operative mortality [odds ratio (OR): 5.25, 95% CI: 4.74-5.82, P <0.0001], stroke (OR: 2.05, 95% CI: 1.72-2.43, P <0.0001), renal (OR: 4.13, 95% CI: 3.43-4.39 P <0.0001) respiratory complications (OR: 3.91, 95% CI: 2.96-5.17, P <0.0001), longer hospital length of stay (mean difference: 2.69, 95% CI: 1.68-3.69, P <0.0001), and myocardial infarction (OR: 1.85, 95% CI: 1.30-2.65, P =0.0007)., Conclusion: Postoperative bleeding requiring re-exploration is associated with lower long-term survival and increased risk of short-term adverse events including operative mortality, stroke, renal and respiratory complications, and longer hospital length of stay. To improve both short-term and long-term outcomes, strategies to prevent the need for re-exploration are necessary., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

Background/Objectives: The demographic shift towards an aging population necessitates a reevaluation of surgical interventions like coronary artery bypass grafting (CABG) in octogenarians. This study aims to elucidate the outcomes of CABG in octogenarians with heart failure and reduced ejection fraction (HFrEF), a group traditionally considered at high risk for such procedures. Methods: Conducted across four academic hospitals in Germany from 2017 to 2023, this retrospective multicenter study assessed 100 patients (50 octogenarians ≥80 years and 50 non-octogenarians <80 years) with HFrEF undergoing isolated CABG. Through propensity score matching, the study aimed to compare the incidence of major adverse cardiac and cerebrovascular events (MACCEs), as well as other clinical endpoints, between the two groups. Statistical analyses included chi-square, ANOVA, Mann-Whitney U test, Cox regression, and logistic regression, aiming to identify significant differences in outcomes. Results: The study revealed no significant difference in the combined incidence of MACCEs between octogenarians and non-octogenarians (OR: 0.790, 95% CI: 0.174-3.576, p = 0.759). Mortality rates were similar across groups (7% each, p = 1.000), as were occurrences of postoperative myocardial infarction (2% each, p = 1.000) and stroke (3% total). Secondary outcomes like delirium (17% total, no significant age group difference, p = 0.755), acute kidney injury (18% total, p = 0.664), and the need for dialysis (14% total, p = 1.000) also showed no differences between age groups. Interestingly, non-octogenarians required more packed red blood cells during their stay ( p = 0.008), while other postoperative care metrics, such as hospital and ICU length of stay and ventilation hours, were comparable across groups. Conclusion: This multicenter study highlights that CABG is a viable and safe surgical option for octogenarians with HFrEF, challenging prior assumptions about the elevated risks associated with performing this procedure in older patients. The absence of significant differences in the incidence of MACCEs and other postoperative complications across age groups emphasizes the importance of careful patient selection and perioperative management. These findings advocate for a more inclusive approach to surgical treatment for octogenarians with HFrEF, suggesting that age alone should not be a determinant for CABG eligibility. This study contributes critical insights into optimizing care for a high-risk demographic, indicating a need for tailored guidelines that accommodate the aging population with complex cardiac conditions.

Self-expanding valves (SEV) and balloon-expandable valves (BEV) for transcatheter aortic valve implantation (TAVI) have their own features. There is a growing interest in long-term outcomes with the adoption of lifetime management in younger patients. To evaluate late outcomes in TAVI with SEV versus BEV, we performed a study-level meta-analysis of reconstructed time-to-event data published by May 31, 2023. We found no statistically significant difference in all-cause death after TAVI with SEV versus BEV. Randomized controlled trials are warranted to validate our results., Competing Interests: Disclosure P.

We reviewed the cardiac surgical literature for 2023. PubMed displayed almost 34,000 hits for the search term "cardiac surgery AND 2023." We used a PRISMA approach for a results-oriented summary. Key manuscripts addressed the mid- and long-term effects of invasive treatment options in patient populations with coronary artery disease (CAD), comparing interventional therapy (percutaneous coronary intervention [PCI]) with surgery (coronary artery bypass graft [CABG]). The literature in 2023 again confirmed the excellent long-term outcomes of CABG compared with PCI in patients with left main stenosis, specifically in anatomically complex chronic CAD, but even in elderly patients, generating further support for an infarct-preventative effect as a prognostic mechanism of CABG. For aortic stenosis, a previous trend of an early advantage for transcatheter (transcatheter aortic valve implantation [TAVI]) and a later advantage for surgical (surgical aortic valve replacement) treatment was also re-confirmed by many studies. Only the Evolut Low Risk trial maintained an early advantage of TAVI over 4 years. In the mitral and tricuspid field, the number of interventional publications increased tremendously. A pattern emerges that clinical benefits are associated with repair quality, making residual regurgitation not irrelevant. While surgery is more invasive, it currently generates the highest repair rates and longest durability. For terminal heart failure treatment, donor pool expansion for transplantation and reducing adverse events in assist device therapy were issues in 2023. Finally, the aortic diameter related to adverse events and technical aspects of surgery dominated in aortic surgery. This article summarizes publications perceived as important by us. It cannot be complete nor free of individual interpretation, but provides up-to-date information for patient-specific decision-making., Competing Interests: None declared., (Thieme.

Introduction: Lipoprotein(a) (Lp[a]) is a variant of low-density lipoprotein (LDL) and has been associated with increased risk of vascular inflammation and thrombosis. Coronary artery bypass grafting (CABG) has been associated with local inflammation of the myocardium. It is plausible, therefore, that patients with elevated baseline Lp(a) may be prone to unfavorable clinical outcomes following CABG. We evaluate differences in outcomes between CABG patients with high and low serum Lp(a) in this meta-analysis., Evidence Acquisition: A comprehensive literature search was performed to identify studies reporting outcomes in CABG patients stratified by preoperative Lp(a) level. When possible, the outcomes were pooled in a meta-analysis. We assessed post-operative mortality, major cardiovascular events, stroke occurrence and saphenous graft occlusion., Evidence Synthesis: Eight studies involving 8681 patients were included. Articles used varying cut-offs for high versus low Lp(a), and outcomes varied. In the three studies evaluating mortality, two showed no statistically significant difference between groups while one reported increased mortality associated with high Lp(a) level. Both studies investigating major adverse cardiovascular events reported higher risk in patients with high Lp(a). A study-level meta-analysis of four studies reporting saphenous vein graft occlusion incidence after CABG was performed. High (≥30 mg/dL) preoperative Lp(a) was not associated with an increased risk of graft occlusion compared with low (<30 mg/dL) preoperative Lp(a) (OR=1.88, 95% CI: 0.66-5.36; P=0.15)., Conclusions: Studies evaluating the impact of Lp(a) on outcomes in CABG patients are few, with heterogenous cut-offs and outcomes. In the limited published studies, Lp(a) level was not associated with graft occlusion.

Objectives: The association between obesity and graft failure after coronary artery bypass grafting has not been previously investigated., Methods: We pooled individual patient data from randomized clinical trials with systematic postoperative coronary imaging to evaluate the association between obesity and graft failure at the individual graft and patient levels. Penalized cubic regression splines and mixed-effects multivariable logistic regression models were performed., Results: Six trials comprising 3928 patients and 12 048 grafts were included. The median time to imaging was 1.03 (interquartile range 1.00-1.09) years. By body mass index (BMI) category, 800 (20.4%) patients were normal weight (BMI 18.5-24.9), 1668 (42.5%) were overweight (BMI 25-29.9), 983 (25.0%) were obesity class 1 (BMI 30-34.9), 344 (8.8%) were obesity class 2 (BMI 35-39.9) and 116 (2.9%) were obesity class 3 (BMI 40+). As a continuous variable, BMI was associated with reduced graft failure [adjusted odds ratio (aOR) 0.98 (95% confidence interval (CI) 0.97-0.99)] at the individual graft level. Compared to normal weight patients, graft failure at the individual graft level was reduced in overweight [aOR 0.79 (95% CI 0.64-0.96)], obesity class 1 [aOR 0.81 (95% CI 0.64-1.01)] and obesity class 2 [aOR 0.61 (95% CI 0.45-0.83)] patients, but not different compared to obesity class 3 [aOR 0.94 (95% CI 0.62-1.42)] patients. Findings were similar, but did not reach significance, at the patient level., Conclusions: In a pooled individual patient data analysis of randomized clinical trials, BMI and obesity appear to be associated with reduced graft failure at 1 year after coronary artery bypass grafting., (© The Author(s) 2024.

Background:  This study aimed to assess the influence of the model of end-stage liver disease without International Normalized Ratio (INR) (MELD-XI) score on outcomes after elective coronary artery bypass surgery (CABG) without (Off-Pump) or with (On-Pump) cardiopulmonary bypass., Methods:  We calculated MELD-XI (5.11 × ln serum bilirubin + 11.76 × ln serum creatinine in + 9.44) for 3,535 consecutive patients having undergone elective CABG between 2009 and 2020. A MELD-XI threshold was determined using the Youden Index based on receiver operating characteristics. Propensity score matching and logistic regression was performed to identify risk factors for inhospital mortality and Major Adverse Cardiac and Cerebrovascular Event (MACCE)., Results:  Patients were 68 ± 10 years old (76% male). Average MELD-XI was 10.9 ± 3.25. The MELD-XI threshold was 11. Patients below this threshold had somewhat lower EuroSCORE II than those above (3.5 ± 4 vs. 4.1 ± 4.7, p  < 0.01), but mortality was almost four times higher above the threshold (below 1.5% vs. above 6.2%, p  < 0.001). Two-thirds of patients received Off-Pump CABG. There was a trend towards higher risk in Off-Pump patients. Mortality was numerically but not statistically different to On-Pump below the MELD XI threshold (1.3 vs. 2.2%, p  = 0.34) and was significantly lower above the threshold (4.9 vs. 8.9%, p  < 0.02). Off-Pump above the threshold was also associated with less low-output syndrome and fewer strokes. Equalizing baseline differences by propensity matching verified the significant mortality difference above the threshold. Multivariable regression analysis revealed MELD-XI, On-Pump, atrial fibrillation, and the De Ritis quotient (Aspartate aminotransferase (ASAT)/Alanine Aminotransferase (ALAT)) as independent predictors of mortality., Conclusion:  Elective CABG patients with elevated MELD-XI scores are at increased risk for perioperative mortality and morbidity. This risk can be significantly mitigated by performing CABG Off-Pump., Competing Interests: None declared., (Thieme. All rights reserved.)

Objectives:  Mechanisms of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) differ as CABG provides surgical collateralization and may prolong life by preventing future myocardial infarctions (MIs). However, evidence for CABG in patients with chronic total occlusion (CTO) has not been fully elucidated and the impact of PCI is discussed controversially., Methods:  We performed a meta-analysis of studies comparing outcomes in patients with/without multivessel disease undergoing CABG or PCI for CTO. The primary outcome was long-term all-cause mortality (≥5 years). Secondary outcomes were MIs, repeat revascularization, cardiac mortality, major adverse cardiovascular events, and stroke, as well as short-term mortality (30 days/in-hospital) and stroke. A pooled Kaplan-Meier survival curve after reconstruction analysis was generated. Random-effects models were used., Results:  Six studies totaling 12,504 patients were included. In the pooled Kaplan-Meier analysis, PCI showed a significantly higher risk of death in the follow-up compared with CABG (hazard ratio [HR]: 2.12, 95% confidence interval [CI]: 1.88-2.38, p  < 0.01). During the observation period, PCI was also associated with higher rates of MI (odds ratio [OR]: 2.86, 95% CI: 1.82-4.48, p  < 0.01) and more repeat revascularization (OR: 4.88, 95% CI: 1.99-11.91, p  = 0.0005). The other outcomes did not show significant differences., Conclusion:  CABG is associated with superior survival to PCI over time in patients with CTO who are eligible for both PCI and CABG. This survival advantage is associated with fewer events of MI and repeat revascularization., Competing Interests: None declared., (Thieme. All rights reserved.)

Background: The use of extracorporeal life support (ECLS) in patients after surgical repair for acute type A aortic dissection (ATAAD) has not been well documented., Methods: We performed a systematic review and meta-analysis to assess the outcomes of ECLS after surgery for ATAAD with data published by October 2023 in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines. The protocol was registered in PROSPERO (CRD42023479955)., Results: Twelve observational studies met our eligibility criteria, including 280 patients. Mean age was 55.0 years and women represented 25.3% of the overall population. Although the mean preoperative left ventricle ejection fraction was 59.8%, 60.8% of patients developed left ventricle failure and 34.0% developed biventricular failure. Coronary involvement and malperfusion were found in 37.1% and 25.6%, respectively. Concomitant coronary bypass surgery was performed in 38.5% of patients. Regarding ECLS, retrograde flow (femoral) was present in 39.9% and central cannulation was present in 35.4%. In-hospital mortality was 62.8% and pooled estimate of successful weaning was 50.8%. Neurological complications, bleeding and renal failure were found in 25.9%, 38.7%, and 65.5%, respectively., Conclusion: ECLS after surgical repair for ATAAD remains associated with high rates of in-hospital death and complications, but it still represents a chance of survival in critical situations. ECLS remains a salvage attempt and surgeons should not try to avoid ECLS at all costs after repairing an ATAAD case., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Ibrahim Sultan receives institutional research support from Abbott, Artivion, Boston Scientific, Edwards, Medtronic, Terumo Aortic.

Objective: To evaluate the association of a validated chest computed tomography (Chest-CT) severity score in COVID-19 patients with their respiratory outcome in the Intensive Care Unit., Methods: A single-center, prospective study evaluated patients with positive RT-PCR for COVID-19, who underwent Chest-CT and had a final COVID-19 clinical diagnosis needing invasive mechanical ventilation in the ICU. The admission chest-CT was evaluated according to a validated Chest-CT Severity Score in COVID-19 (Chest-CTSS) divided into low ≤50% (<14 points) and >50% high (≥14 points) lung parenchyma involvement. The association between the initial score and their pulmonary clinical outcomes was evaluated., Results: 121 patients were clustered into the > 50% lung involvement group and 105 patients into the ≤ 50% lung involvement group. Patients ≤ 50% lung involvement (<14 points) group presented lower PEEP levels and FiO2 values, respectively GEE P = 0.09 and P = 0.04. The adjusted COX model found higher hazard to stay longer on invasive mechanical ventilation HR: 1.69, 95% CI, 1.02-2.80, P = 0.042 and the adjusted logistic regression model showed increased risk ventilator-associated pneumonia OR = 1.85 95% CI 1.01-3.39 for COVID-19 patients with > 50% lung involvement (≥14 points) on Chest-CT at ICU admission., Conclusion: COVID-19 patients with >50% lung involvement on Chest-CT admission presented higher chances to stay longer on invasive mechanical ventilation and more chances to developed ventilator-associated pneumonia., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Esper Treml et al.

Objective: Minimally invasive cardiac surgery (MICS) is increasing worldwide. In most cases, the surgical technique includes cannulation of the groin for the establishment of cardiopulmonary bypass, requiring a second surgical incision (SC) for exposure and cannulation of the femoral vessels. With the introduction of arterial closure devices, percutaneous cannulation (PC) of the groin has become a possible alternative. We performed a meta-analysis and systematic review to compare clinical endpoints between the patients who underwent PC and SC for MICS., Methods: Three databases were assessed. The primary outcome was any access site complication. Secondary outcomes were perioperative mortality, any wound complication, any vascular complication, lymphatic complications, femoral/iliac stenosis, stroke, procedural duration, and hospital length of stay (LOS). A random effects model was performed., Results: A total of 5 studies with 2,038 patients were included. When compared with PC, patients who underwent SC showed a higher incidence of any access site complication (odds ratio [OR] = 3.09, 95% confidence interval [CI]: 1.87 to 5.10, P < 0.01), any wound complication (OR = 10.10, 95% CI: 3.31 to 30.85, P < 0.01), lymphatic complication (OR = 9.37, 95% CI: 2.15 to 40.81, P < 0.01), and longer procedural duration (standardized mean difference = 0.31, 95% CI: 0.12 to 0.51, P < 0.01). There was no significant difference between the 2 groups regarding perioperative mortality, any vascular complication, femoral/iliac stenosis, stroke, or hospital LOS., Conclusions: The analysis suggests that surgical groin cannulation in MICS is associated with a higher incidence of any access site complication (especially wound complication and lymphatic fistula) and with a longer procedural time compared with PC. There was no difference in perioperative mortality., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Infective endocarditis represents a life-threatening disease with high mortality rates. A fraction of patients receives exclusively conservative antibiotic treatment due to their comorbidities and high operative risk, despite fulfilling criteria for surgical therapy. The aim of the present study is to compare outcomes in patients with infective endocarditis and indication for surgical therapy in those who underwent or did not undergo valve surgery., Methods and Results: Three databases were systematically assessed. A pooled analysis of Kaplan-Meier-derived reconstructed time-to-event data from studies with longer follow-up comparing conservative and surgical treatment was performed. A landmark analysis to further elucidate the effect of surgical intervention on mortality was carried out. Four studies with 3003 patients and median follow-up time of 7.6 months were included. Overall, patients with an indication for surgery who were surgically treated had a significantly lower risk of mortality compared with patients who received conservative treatment (hazard ratio [HR], 0.27 [95% CI, 0.24-0.31], P <0.001). The survival analysis in the first year showed superior survival for patients who underwent surgery when compared with those who did not at 1 month (87.6% versus 57.6%; HR, 0.31 [95% CI, 0.26-0.37], P <0.01), at 6 months (74.7% versus 34.6%) and at 12 months (73.3% versus 32.7%)., Conclusions: Based on the findings of this study-level meta-analysis, patients with infective endocarditis and formal indication for surgical intervention who underwent surgery are associated with a lower risk of short- and long-term mortality when compared with conservative treatment.

Objectives: Midline sternotomy is the main surgical access for cardiac surgeries. The most prominent complication of sternotomy is sternal wound infection (SWI). The use of a thorax support vest (TSV) that limits thorax movement and ensures sternal stability has been suggested to prevent postoperative SWI., Methods: We performed a meta-analysis to evaluate differences in clinical outcomes with and without the use of TSV after cardiac surgery in randomized trials. The primary outcome was deep SWI (DSWI). Secondary outcomes were superficial SWI, sternal wound dehiscence, and hospital length of stay (LOS). A trial sequential analysis was performed. Fixed (F) and random effects (R) models were calculated., Results: A total of 4 studies (3820 patients) were included. Patients who wore the TSV had lower incidence of DSWI [odds ratio (OR) = F: 0.24, 95% confidence interval (CI), 0.13-0.43, P < 0.01; R: 0.24, 0.04-1.59, P = 0.08], sternal wound dehiscence (OR = F: 0.08, 95% CI, 0.02-0.27, P < 0.01; R: 0.10, 0.00-2.20, P = 0.08) and shorter hospital LOS (standardized mean difference = F: -0.30, -0.37 to -0.24, P < 0.01; R: -0.63, -1.29 to 0.02, P = 0.15). There was no difference regarding the incidence of superficial SWI (OR = F: 0.71, 95% CI, 0.34-1.47, P = 0.35; R: 0.64, 0.10, 4.26, P = 0.42). The trial sequential analysis, however, showed that the observed decrease in DSWI in the TSV arm cannot be considered conclusive based on the existing evidence., Conclusions: This meta-analysis suggests that the use of a TSV after cardiac surgery could potentially be associated with a reduction in sternal wound complications. However, despite the significant treatment effect in the available studies, the evidence is not solid enough to provide strong practice recommendations., (© The Author(s) 2024.

Objective: This study assesses predictors for postoperative delirium (POD) and ICU stay durations in HFrEF patients undergoing CABG, focusing on ONCAB versus OPCAB surgical methods. Summary Background Data: In cardiac surgery, especially CABG, POD significantly impacts patient recovery and healthcare resource utilization. With varying incidences based on surgical techniques, this study provides an in-depth analysis of POD in the context of HFrEF patients, a group particularly susceptible to this complication. Methods: A retrospective analysis of 572 patients who underwent isolated CABG surgery with a preoperative ejection fraction under 40% was conducted at four German university hospitals. Patients were categorized into ONCAB and OPCAB groups for comparative analysis. Results: Age and Euro Score II were significant predictors of POD. The ONCAB group showed higher incidences of re-sternotomy (OR: 3.37), ECLS requirement (OR: 2.29), and AKI (OR: 1.49), whereas OPCAB was associated with a lower incidence of delirium. Statistical analysis indicated a significant difference in ICU stay durations between the two groups, influenced by surgical complexity and postoperative complications. Conclusions: This study underscores the importance of surgical technique in determining postoperative outcomes in HFrEF patients undergoing CABG. OPCAB may offer advantages in reducing POD incidence. These findings suggest the need for tailored surgical decisions and comprehensive care strategies to enhance patient recovery and optimize healthcare resources.

We present the case of a minimally invasive surgical correction for failed percutaneous atrial septal defect (ASD) closure in a 57-year-old female patient with residual ASD, tricuspid regurgitation, atrial fibrillation, and embolization of one of two occluders to the superior mesenteric artery. Our surgical approach consisted of anterolateral minithoracotomy, aortic and femoral vein cannulation, cryoablation, cardiac device removal, closure of ASD with autologous pericardium, and tricuspid repair. The procedure was uneventful and patient was discharged home on postoperative day 4., Competing Interests: Conflict of Interest None declared., (The Author(s).

Objectives: Multi-organ failure is one of the leading causes of mortality after cardiac surgery for infective endocarditis (IE). Although the randomized evidence does not support the use of haemoadsorption during cardiac surgery for IE, observational studies suggest a beneficial effect in selected patient groups. Staphylococcus aureus is the most common pathogen, and its presence is an independent mortality predictor. We aimed to analyse the effect of haemoadsorption in patients with IE caused by S. aureus., Methods: This is a post hoc analysis of the REMOVE trial that randomized 288 patients with IE who underwent cardiac surgery with haemoadsorption using CytoSorb® or control. The primary outcome was ΔSequential Organ Failure Assessment (SOFA), defined as the difference between the mean total postoperative and baseline SOFA score within 24 h of surgery., Results: Among the total of 282 patients included in the modified intention-to-treat analysis of the REMOVE trial, 73 (25.9%) had S. aureus IE (38 patients in the haemoadsorption group and 35 patients in the control group). The overall ΔSOFA did not differ between the intervention groups in patients with S. aureus IE (mead difference = -0.4, 95% confidence interval -2.3 to 1.4, P = 0.66) and neither did 30-day mortality (hazard ratios = 1.32, 95% confidence interval 0.53-3.28, P = 0.55). No differences were observed with regard to any of the other secondary outcomes., Conclusions: Based on a post hoc analysis from REMOVE trial, the intraoperative use of haemoadsorption in patients with S. aureus IE was not associated with reduction of postoperative organ dysfunction, 30-day mortality or other major clinical end points., (© The Author(s) 2024.
