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.

- Abstract
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.

- Abstract
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.

- Abstract
Background : This retrospective multicenter study investigates the impact of obesity on short-term surgical outcomes in patients with heart failure and reduced ejection fraction (HFrEF) undergoing coronary artery bypass grafting (CABG). Given the rising global prevalence of obesity and its known cardiovascular implications, understanding its specific effects in high-risk groups like HFrEF patients is crucial. Methods : The study analyzed data from 574 patients undergoing CABG across four German university hospitals from 2017 to 2023. Patients were stratified into 'normal weight' ( n = 163) and 'obese' ( n = 158) categories based on BMI (WHO classification). Data on demographics, clinical measurements, health status, cardiac history, intraoperative management, postoperative outcomes, and laboratory insights were collected and analyzed using Chi-square, ANOVA, Kruskal-Wallis, and binary logistic regression. Results : Key findings are a significant higher mortality rate (6.96% vs. 3.68%, p = 0.049) and younger age in obese patients (mean age 65.84 vs. 69.15 years, p = 0.003). Gender distribution showed no significant difference. Clinical assessment scores like EuroScore II and STS Score indicated no differences. Paradoxically, the preoperative left ventricular ejection fraction (LVEF) was higher in the obese group (32.04% vs. 30.34%, p = 0.026). The prevalence of hypertension, COPD, hyperlipidemia, and other comorbidities did not significantly differ. Intraoperatively, obese patients required more packed red blood cells ( p = 0.026), indicating a greater need for transfusion. Postoperatively, the obese group experienced longer hospital stays (median 14 vs. 13 days, p = 0.041) and higher ventilation times (median 16 vs. 13 h, p = 0.049). The incidence of acute kidney injury (AKI) (17.72% vs. 9.20%, p = 0.048) and delirium ( p = 0.016) was significantly higher, while, for diabetes prevalence, there was an indicating a trend towards significance ( p = 0.051) in the obesity group, while other complications like sepsis, and the need for ECLS were similar across groups. Conclusions : The study reveals that obesity significantly worsens short-term outcomes in HFrEF patients undergoing CABG, increasing risks like mortality, kidney insufficiency, and postoperative delirium. These findings highlight the urgent need for personalized care, from surgical planning to postoperative strategies, to improve outcomes for this high-risk group, urging further tailored research.

- Abstract
Objective: This study aimed to compare postoperative outcomes and 30-day mortality in patients with reduced ejection fraction (<40%) who underwent isolated coronary artery bypass grafting (CABG) with (ONCAB) and without (OPCAB) the use of cardiopulmonary bypass., Methods: data from four university hospitals in Germany, spanning from January 2017 to December 2021, were retrospectively analyzed. A total of 551 patients were included in the study, and various demographic, intraoperative, and postoperative data were compared., Results: demographic parameters did not exhibit any differences. However, the OPCAB group displayed notably higher rates of preoperative renal insufficiency, urgent surgeries, and elevated EuroScore II and STS score. During surgery, the ONCAB group showed a significantly higher rate of complete revascularization, whereas the OPCAB group required fewer intraoperative transfusions. No disparities were observed in 30-day/in-hospital mortality for the entire cohort and the matched population between the two groups. Subsequent to surgery, the OPCAB group demonstrated significantly shorter mechanical ventilation times, reduced stays in the intensive care unit, and lower occurrences of ECLS therapy, acute kidney injury, delirium, and sepsis., Conclusions: the study's findings indicate that OPCAB surgery presents a safe and viable alternative, yielding improved postoperative outcomes in this specific patient population compared to ONCAB surgery. Despite comparable 30-day/in-hospital mortality rates, OPCAB patients enjoyed advantages such as decreased mechanical ventilation durations, shorter ICU stays, and reduced incidences of ECLS therapy, acute kidney injury, delirium, and sepsis. These results underscore the potential benefits of employing OPCAB as a treatment approach for patients with coronary heart disease and reduced ejection fraction.

- Abstract
Objective: Isolated tricuspid valve surgery is perceived as high-risk. This perception is nurtured by patients who often present with substantial liver dysfunction, which is inappropriately reflected in current surgical risk scores (eg, the Society of Thoracic Surgeons [STS] score has no specific tricuspid model). The Model for End-Stage Liver Disease (MELD) has was developed as a measure for the severity of liver dysfunction. We report scores and outcomes for our patient population., Methods: We calculated STS, European System for Cardiac Operative Risk Evaluation (EuroSCORE) II (ESII), and MELD scores for all of our patients who received isolated tricuspid valve surgery between 2011 and 2020 (n = 157). We determined the MELD score, stratified patients into 3 groups (MELD <10: low, n = 53; 10 to <20: intermediate, n = 78; ≥20: high, n = 26) and describe associated outcomes., Results: Patients were 72 ± 10 years old and 43% were male. Mean STS score was 4.9 ± 3.5% and ESII was 7.2 ± 6.6%. Mortality was 8.9% at 30 days and 65% at latest follow-up (95% CI, 51%-76%). Median follow-up was 4.4 years (range, 0-9.7 years). Although ESII and STS score accurately predicted 30-day mortality at low MELD scores (observed to expected [O/E] for ESII score = 0.8 and O/E for STS score = 1.0) and intermediate MELD (O/E for ESII score = 0.7, O/E for STS score = 1.0), mortality was underestimated at high MELD (O/E for ESII score = 3.0, O/E for STS score = 4.7). This subgroup also had higher incidence of new-onset hemodialysis. Besides MELD category, recent congestive heart failure, endocarditis, and hemodialysis were also associated with 30-day mortality., Conclusions: For isolated tricuspid valve regurgitation, classic surgical risk stratification with STS or ESII scores failed to predict perioperative mortality if there was evidence of severe liver dysfunction. Preoperative MELD assessment might be useful to assist in proper risk assessment for isolated tricuspid valve surgery., (Copyright © 2022 The American Association for Thoracic Surgery.
