Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Impact of Age on the Relationship between Cross-Clamp Time and Mortality in Cardiac Surgery. Thorac Cardiovasc Surg 2024.

Abstract
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.

Abstract
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.

Abstract
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.

Subclinical hypothyroidism and clinical outcomes after cardiac surgery: A systematic review and meta-analysis. JTCVS OPEN 2024; 18:64-79. [PMID: 38690432 PMCID: PMC11056480 DOI: 10.1016/j.xjon.2024.02.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 01/26/2024] [Accepted: 02/13/2024] [Indexed: 05/02/2024]
Abstract
Background Subclinical hypothyroidism (SCH) is associated with major adverse cardiovascular events. Despite the recognized negative impact of SCH on cardiovascular health, research on cardiac postoperative outcomes with SCH has yielded conflicting results, and patients are not currently treated for SCH before cardiac surgery procedures. Methods We performed a study-level meta-analysis on the impact of SCH on patients undergoing nonurgent cardiac surgery, including coronary artery bypass grafting and valve and aortic surgery. The primary outcome was operative mortality. Secondary outcomes were hospital length of stay (LOS), intensive care unit (ICU) stay, postoperative atrial fibrillation (POAF), intra-aortic balloon pump (IABP) use, renal complications, and long-term all-cause mortality. Results Seven observational studies, with a total of 3445 patients, including 851 [24.7%] diagnosed with SCH and 2594 [75.3%] euthyroid patients) were identified. Compared to euthyroid patients, the patients with SCH had higher rates of operative mortality (odds ratio [OR], 2.57; 95% confidence interval [CI], 1.09-6.04; P = .03), prolonged hospital LOS (standardized mean difference, 0.32; 95% CI, 0.02-0.62; P = .04), a higher rate of renal complications (OR, 2.53; 95% CI, 1.74-3.69; P < .0001), but no significant differences in ICU stay, POAF, or IABP use. At mean follow-up of 49.3 months, the presence of SCH was associated with a higher rate of all-cause mortality (incidence rate ratio, 1.82; 95% CI, 1.18-2.83; P = .02). Conclusions Patients with SCH have higher operative mortality, prolonged hospital LOS, and increased renal complications after cardiac surgery. Achieving and maintaining a euthyroid state prior to and after cardiac surgery procedures might improve outcomes in these patients.

Abstract
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.

Unraveling the Predictors for Delirium and ICU Stay Duration in Patients with Heart Failure and Reduced Ejection Fraction (HFrEF) Undergoing Coronary Artery Bypass Grafting-A Multicentric Analysis. Biomedicines 2024; 12:749. [PMID: 38672105 PMCID: PMC11048437 DOI: 10.3390/biomedicines12040749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 03/21/2024] [Accepted: 03/26/2024] [Indexed: 04/28/2024] Open
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
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 hemoadsorption during cardiac surgery for IE, observational studies suggest a beneficial effect in selected patient groups. S. aureus is the most common pathogen, and its presence is an independent mortality predictor. We aimed to analyze the effect of hemoadsorption 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 hemoadsorption 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 hours 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 hemoadsorption group and 35 patients in the control group). The overall ΔSOFA did not differ between the intervention groups in patients with S. aureus IE (MD= -0.4, 95% CI -2.3 to 1.4, p = 0.66) and neither did 30-day mortality (HR = 1.32, 95% CI 0.53 to 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 hemoadsorption in patients with S. aureus IE was not associated with reduction of postoperative organ dysfunction, 30-day mortality or other major clinical end-points.

Abstract
Objectives: Benefits of tricuspid valve repair (TVR) in left ventricular assist device (LVAD) patients have been questioned. High TVR failure rates have been reported. Remaining or recurring TR was found to be a risk factor for right heart failure (RHF). Therefore, we assessed our experience. Methods: Since 12/2010, 195 patients have undergone LVAD implantation in our center. Almost half (n = 94, 48%) received concomitant TVR (LVAD+TVR). These patients were included in our analysis. Echocardiographic and clinical data were assessed. Median follow-up was 2.8 years (7 days-0.6 years). Results were correlated with clinical outcomes. Results: LVAD+TVR patients were 59.8 ± 11.4 years old (89.4% male) and 37.3% were INTERMACS level 1 and 2. Preoperative TR was moderate in 28 and severe in 66 patients. RV function was severely impaired in 61 patients reflected by TAPSE-values of 11.2 ± 2.9 mm (vs. 15.7 ± 3.8 mm in n = 33; p < 0.001). Risk for RHF according to EUROMACS-RHF risk score was high (>4 points) in 60 patients, intermediate (>2-4 points) in 19 and low (0-2 points) in 15. RHF occurred in four patients (4.3%). Mean duration of echocardiographic follow-up was 2.8 ± 2.3 years. None of the patients presented with severe and only five (5.3%) with moderate TR. The vast majority (n = 63) had mild TR, and 26 patients had no/trace TR. Survival at 1, 3 and 5 years was 77.4%, 68.1% and 55.6%, 30-day mortality was 11.7% (n = 11). Heart transplantation was performed in 12 patients (12.8%). Conclusions: Contrary to expectations, concomitant TVR during LVAD implantation may result in excellent repair durability, which appears to be associated with low risk for RHF.

Respect Versus Resect Approaches for Mitral Valve Repair: A Meta-Analysis of Reconstructed Time-to-Event Data. Am J Cardiol 2024; 213:5-11. [PMID: 38104750 DOI: 10.1016/j.amjcard.2023.12.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 11/15/2023] [Accepted: 12/01/2023] [Indexed: 12/19/2023]
Abstract
Mitral valve repair (MVr) has been associated with superior long-term survival and freedom from valve-related complications compared with mitral valve replacement for primary mitral regurgitation (MR). The 2 main approaches for MVr are chordal replacement ("respect approach") and leaflet resection ("resect approach"). We performed a systematic review and a meta-analysis using 3 search databases to compare the long-term end points between both approaches. The primary end point was long-term survival. The secondary end points were long-term MR recurrence and reoperation. After reconstruction of time-to-event data for the individual survival analysis, pooled Kaplan-Meier curves for the end points were generated. A total of 14 studies (5,565 patients) were included in the analysis. The respect approach was associated with superior survival compared with the resect approach in the overall sample (hazard ratio [HR] 0.73, 95% confidence interval [CI] 0.56 to 0.96, p = 0.024, n = 3,901 patients) but not in the risk-adjusted sample (HR 1.00, 95% CI 0.55 to 1.82, p = 0.991, n = 620 patients). There was no difference between the approaches in the rate of MR recurrence in the overall sample (HR 1.39, 95% CI 0.92 to 2.08, p = 0.116, n = 1,882 patients) or in the risk-adjusted sample (HR 1.62, 95% CI 0.76 to 3.47, p = 0.211, n = 288 patients). The data for reoperation were only available in the overall sample and did not reveal a difference (HR 0.92, 95% CI 0.62 to 1.35, p = 0.663, n = 3,505 patients). In conclusion, the current evidence suggests no difference in long-term mortality, MR recurrence, or reoperation between the resect and respect approaches for MVr after adjusting for patient risk factors. More long-term follow-up data are warranted.

Outcomes According to Coronary Revascularization Modality in the ISCHEMIA Trial. J Am Coll Cardiol 2024; 83:549-558. [PMID: 37956961 DOI: 10.1016/j.jacc.2023.11.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 11/03/2023] [Accepted: 11/07/2023] [Indexed: 11/21/2023]
Abstract
BACKGROUND In the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial, the risk of ischemic events was similar in patients with stable coronary artery disease treated with an invasive (INV) strategy of angiography and percutaneous coronary intervention (PCI) or surgical (coronary artery bypass grafting [CABG]) coronary revascularization and a conservative (CON) strategy of initial medical therapy. OBJECTIVES The authors analyzed separately the outcomes of INV patients treated with PCI or CABG. METHODS Patients without preceding primary outcome events were categorized as INV-PCI or INV-CABG from the time of revascularization. The ISCHEMIA primary outcome (composite of cardiovascular death, protocol-defined myocardial infarction or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest) was used. RESULTS Among INV-CABG patients, primary outcome events occurred in 84 of 512 (16.4%) at a median follow-up of 2.85 years; 48 events (57.1%) occurred within 30 days after CABG, including 40 procedural MIs. Among INV-PCI patients, primary outcome events occurred in 147 of 1,500 (9.8%) at median follow-up of 2.94 years; 31 of which (21.1%) occurred within 30 days after PCI, including 24 procedural MIs. In comparison, 352 of 2,591 CON patients (13.6%) had primary outcome events at a median follow-up of 3.2 years, 22 of which (6.3%) occurred within 30 days of randomization. The adjusted primary outcome risks were higher after both CABG and PCI within 30 days (HR: 16.25 [95% CI: 11.44-23.07] and HR: 2.99 [95% CI: 1.97-4.53]) and lower thereafter (0.63 [95% CI: 0.44-0.89] and 0.66 [95% CI: 0.53-0.82]). CONCLUSIONS In ISCHEMIA, early revascularization by PCI and CABG was associated with higher early risks and lower long-term risks of cardiovascular events compared with CON. The early risk was greatest after CABG, owing to protocol-defined procedural MIs.

Comparing outcomes between coronary artery bypass grafting and percutaneous coronary intervention in octogenarians with left main or multivessel disease. Sci Rep 2023; 13:22323. [PMID: 38102297 PMCID: PMC10724226 DOI: 10.1038/s41598-023-49069-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 12/04/2023] [Indexed: 12/17/2023] Open
Abstract
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 (MI). However, CABG benefits are unclear in octogenarians, where surgical risk is often perceived as higher and PCI is chosen more liberally. We performed a meta-analysis of studies comparing outcomes in octogenarians with left main or multivessel disease who underwent CABG or PCI. Primary outcome was late mortality (> 5 years). Secondary outcomes were perioperative mortality, MI, re-revascularization (R-R), acute renal failure (ARF), and stroke. Fourteen studies with 17,942 patients were included. CABG was associated with lower late mortality (hazard ratio, HR: 1.23, 95% confidence interval: CI 1.05-1.44, p < 0.01). In the pooled Kaplan-Meier analysis CABG showed significantly lower risk of death in the follow-up compared to PCI (HR: 1.08, 95%CI 1.02-1.41, p = 0.005). Landmark analyses confirmed the survival advantage of CABG over PCI after 21.5 months of follow-up (HR: 1.31, 1.19-1.44, p < 0.0001), but suggested advantage of PCI over CABG in the first 30-days (HR: 0.72, 0.64-0.82, p < 0.0001) and comparable survival from 1 to 21.5 months (HR: 0.98, 0.92-1.05, p = 0.652). We found lower risk for MI and R-R after CABG but higher perioperative mortality and no differences in ARF and stroke. CABG appears superior to PCI over time in octogenarians with complex CAD. This survival advantage is associated with fewer events of MI and R-R; however, it comes with an increased risk in perioperative mortality.

Abstract
BACKGROUND Making the right decision in stressful situations is required for goal-oriented action in cardiac surgery. Current labor laws prevent residents to be subjected to situations that test their stress tolerance. These situations often occur only later in the career. We simulated such conditions in a structured non-stop 36-hour cardiac surgical training course and assessed the participant's performance. METHODS Fourteen advanced residents/junior staff surgeons were selected. The course was conducted in collaboration with the national antiterror police forces that provided coaching for teamplay, leadership, and responsibility awareness. The candidates attended graded and evaluated workshops/lectures and performed academic and surgical tasks. Psychological and surgical skill assessments were conducted at times 0, 12, 24, 36 hours. RESULTS Progressive reductions in individual motivation, associated with increased stress and irritability levels, worsening mood, and fatigue were observed. Long- and short-term memory functions were unaffected and practical surgical performance even increased over time. CONCLUSION Among the candidates, 36 hours of sleep deprivation did not lead to relevant changes in the skills required from a cardiac surgeon in daily life. Importantly, group dynamics substantially improved during the course, suggesting advances in the perception of responsibility and teamwork.

Myocardial protection in cardiac surgery-hindsight from the 2020s. Eur J Cardiothorac Surg 2023; 64:ezad424.

Abstract
Myocardial protection and specifically cardioplegia have been extensively investigated in the beginnings of cardiac surgery. After cardiopulmonary bypass had become routine, more and more cardiac operations were possible, requiring reliable and reproducible protection for times of blood flow interruptions to the most energy-demanding organ of the body. The concepts of hypothermia and cardioplegia evolved as tools to extend cardiac ischaemia tolerance to a degree considered safe for the required operation. A plethora of different solutions and delivery techniques were developed achieving remarkable outcomes with cross-clamp times of up to 120 min and more. With the beginning of the new millennium, interest in myocardial protection research declined and, as a consequence, conventional cardiac surgery is currently performed using myocardial protection strategies that have not changed in decades. However, the context, in which cardiac surgery is currently performed, has changed during this time. Patients are now older and suffer from more comorbidities and, thus, other organs move more and more into the centre of risk assessment. Yet, systemic effects of cardioplegic solutions have never been in the focus of attention. They say hindsight is always 20-20. We therefore review the biochemical principles of ischaemia, reperfusion and cardioplegic extension of ischaemia tolerance and address the concepts of myocardial protection with 'hindsight from the 2020s'. In light of rising patient risk profiles, minimizing surgical trauma and improving perioperative morbidity management becomes key today. For cardioplegia, this means accounting not only for cardiac, but also for systemic effects of cardioplegic solutions.

On- vs. Off-Pump CABG in Heart Failure Patients with Reduced Ejection Fraction (HFrEF): A Multicenter Analysis. Biomedicines 2023; 11:3043.

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
This study aimed to evaluate the effect of two restrictive cumulative fluid balance (CFB) trends on survival and on major clinical outcomes in invasively ventilated patients with moderate to severe respiratory distress syndrome (ARDS) due to SARS-CoV-2. Prospective data collection was conducted on patients in the intensive care unit (ICU) originating from a tertiary university hospital. The primary outcomes were the risk association between the CFB trend during D0 to D7 and 28-day survival. The secondary outcomes were ICU mortality, in-hospital mortality, the need for invasive ventilation at D28, administration of vasoactive drugs at D7, time on invasive ventilation after D7, and length of ICU and hospital stay. 171 patients were enrolled in the study and divided according to their CFB trends during seven days of follow-up using model-based clustering [median CFB negative trend (n = 89) - 279 ml (- 664 to 203) and (n = 82) median CFB positive trend 1362 ml (619-2026)]. The group with CFB negative trend showed a higher chance of surviving 28-day in the ICU (HR: 0.62, 95% CI 0.41-0.94, p = 0.038). Moreover, this group had a reduced length of stay in the ICU, 11 (8-19) days versus 16.5 (9-29) days p = 0.004 and presented lower rates (OR = 0.22; 95% CI 0.09-0.52) of invasive ventilation after 28-days in the ICU. In patients invasively ventilated with moderate to severe ARDS due to COVID-19, the collective who showed a negative trend in the CFB after seven days of invasive ventilation had a higher chance of surviving 28 days in the ICU and lower length of stay in the ICU.

Outcomes of Concomitant Coronary Artery Bypass Grafting in Patients With Infective Endocarditis: A Systematic Review and Meta-Analysis. Am J Cardiol 2023; 205:354-359.

Abstract
It is current practice to perform concomitant coronary artery bypass grafting (CABG) in patients with infective endocarditis who have relevant coronary artery disease. However, CABG may add complexity to the operation. We performed a systematic review and a meta-analysis of studies that presented outcomes from patients who underwent valve surgery because of infective endocarditis with or without concomitant CABG. Three databases were assessed. Perioperative mortality was the primary outcome. Long-term mortality and postoperative stroke were the secondary outcomes. Inverse variance method and random model were performed. Five studies with a total of 5,408 patients were included. Mean follow-up was 8.2 years. Just 1 study addressed exclusively patients with documented coronary artery disease. Perioperative mortality did not differ between patients with or without concomitant CABG (odds ratio 1.53, 95% confidence interval 0.52 to 4.48, p = 0.44). Long-term mortality did not differ between patients who received and those who did not receive concomitant CABG (odds ratio 1.79, confidence interval 0.88 to 3.65, p = 0.11). Only 1 study from a multicenter registry reported data on the occurrence of postoperative stroke, which demonstrated that its incidence after adjustment was 26% in patients with concomitant CABG versus 21% in patients without concomitant CABG (p = 0.003). The results suggest that in endocarditis patients, adding CABG to valve surgery does not affect perioperative or long-term mortality. Data available on the impact of concomitant CABG on neurologic outcomes are limited to a retrospective multicenter registry and suggest that concomitant CABG may be associated with higher postoperative stroke.

Abstract
BACKGROUND Postoperative atrial fibrillation (POAF) is the most frequent complication of cardiac surgery. Despite clinical and economic implications, ample variability in POAF assessment method and definition exist across studies. We performed a study-level meta-analysis to evaluate the influence of POAF assessment method and definition on its incidence and association with clinical outcomes. METHODS AND RESULTS A systematic literature search was conducted to identify studies comparing the outcomes of patients with and without POAF after cardiac surgery that also reported POAF assessment method. The primary outcome was POAF incidence. The secondary outcomes were in-hospital mortality, stroke, intensive care unit length of stay, and postoperative length of stay. Fifty-nine studies totaling 197 774 patients were included. POAF cumulative incidence was 26% (range: 7.3%-53.1%). There were no differences in POAF incidence among assessment methods (27%, [range: 7.3%-53.1%] for continuous telemetry, 27% [range: 7.9%-50%] for telemetry plus daily ECG, and 19% [range: 7.8%-42.4%] for daily ECG only; P>0.05 for all comparisons). No differences in in-hospital mortality, stroke, intensive care unit length of stay, and postoperative length of stay were found between assessment methods. No differences in POAF incidence or any other outcomes were found between POAF definitions. Continuous telemetry and telemetry plus daily ECG were associated with higher POAF incidence compared with daily ECG in studies including only patients undergoing isolated coronary artery bypass grafting. CONCLUSIONS POAF incidence after cardiac surgery remains high, and detection rates are variable among studies. POAF incidence and its association with adverse outcomes are not influenced by the assessment method and definition used, except in patients undergoing isolated coronary artery bypass grafting.

Abstract
PubMed displayed almost 37,000 hits for the search term "cardiac surgery AND 2022." As before, we used the PRISMA approach and selected relevant publications for a results-oriented summary. We focused on coronary and conventional valve surgery, their overlap with interventional alternatives, and briefly assessed surgery for aorta or terminal heart failure. In the field of coronary artery disease (CAD), key manuscripts addressed prognostic implications of invasive treatment options, classically compared modern interventions (percutaneous coronary intervention [PCI]) with surgery (coronary artery bypass grafting [CABG]), and addressed technical aspects of CABG. The general direction in 2022 confirms the superiority of CABG over PCI in patients with anatomically complex chronic CAD and supports an infarct-preventative effect as underlying mechanism. In addition, the relevance of proper surgical technique to achieve durable graft patency and the need for optimal medical treatment in CABG patients was impressively illustrated. In structural heart disease, the comparisons of interventional and surgical techniques have been characterized by prognostic and mechanistic investigations underscoring the need for durable treatment effects and reductions of valve-related complications. Early surgery for most valve pathologies appears to provide significant survival advantages, and two publications on the Ross operation prototypically illustrate an inverse association between long-term survival and valve-related complications. For surgical treatment of heart failure, the first xenotransplantation was certainly dominant, and in the aortic surgery field, innovations in arch surgery prevailed. 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 decision-making and patient information.

Abstract
OBJECTIVE Since there are concerns about the durability of mitral valve repair (MVRp) with minimally invasive techniques in patients with mitral regurgitation (MR), we aimed to evaluate the long-term outcomes of these sternal-sparing approaches when compared with conventional approaches with sternotomy in patients undergoing MVRp. METHODS We performed a systematic review according to a preestablished protocol and performed a pooled analysis of Kaplan-Meier-derived reconstructed time-to-event data from studies with longer follow-up comparing sternal-sparing versus sternotomy approaches for MVRp. Our outcomes of interest were survival, freedom from recurrent MR, and freedom from reoperation. RESULTS Eleven studies met our eligibility criteria comprising 7,596 patients with follow-up (sternal sparing, n = 4,246; sternotomy, n = 3,350). Patients who underwent sternal-sparing MVRp had a significantly lower risk of mortality over time compared with patients who underwent MVRp with sternotomy (hazard ratio [HR] = 0.29, 95% confidence interval [CI]: 0.23 to 0.36, P < 0.001) in the overall analysis. However, we found no statistically significant difference between the groups in the sensitivity analysis with adjusted populations (HR = 0.85, 95% CI: 0.63 to 1.15, P = 0.301). Regarding the outcomes freedom from recurrent MR and freedom from reoperation, we found no statistically significant differences between the groups in the follow-up in both overall and sensitivity analyses. CONCLUSIONS In comparison with MVRp with sternotomy approaches, sternal-sparing MVRp was not associated with worse outcomes in terms of survival, recurrent MR, and reoperations over time.

Outcomes comparison between the first and the subsequent SARS-CoV-2 waves - a systematic review and meta-analysis. Multidiscip Respir Med 2023; 18:933. [PMID: 38155706 PMCID: PMC10690722 DOI: 10.4081/mrm.2023.933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 10/05/2023] [Indexed: 12/30/2023] Open
Abstract
Background In the beginning of the SARS-CoV-2 pandemic, health care professionals dealing with COVID-19 had to rely exclusively on general supportive measures since specific treatments were unknown. The subsequent waves could be faced with new diagnostic and therapeutic tools (e.g., anti-viral medications and vaccines). We performed a meta-analysis and systematic review to compare clinical endpoints between the first and subsequent waves. Methods Three databases were assessed. The primary outcome was in-hospital mortality. The secondary outcomes were intensive care unit (ICU) mortality, ICU length of stay (LOS), acute renal failure, extracorporeal membrane oxygenation (ECMO) implantation, mechanical ventilation time, hospital LOS, systemic thromboembolism, myocarditis and ventilator associated pneumonia. Results A total of 25 studies with 126,153 patients were included. There was no significant difference for the primary endpoint (OR=0.94, 95% CI 0.83-1.07, p=0.35). The first wave group presented higher rates of ICU LOS (SMD= 0.23, 95% CI 0.11-0.35, p<0.01), acute renal failure (OR=1.71, 95% CI 1.36-2.15, p<0.01) and ECMO implantation (OR=1.64, 95% CI 1.06-2.52, p=0.03). The other endpoints did not show significant differences. Conclusions The analysis suggests that the first wave group, when compared with the subsequent waves group, presented higher rates of ICU LOS, acute renal failure and ECMO implantation, without significant difference in in-hospital or ICU mortality, mechanical ventilation time, hospital LOS, systemic thromboembolism, myocarditis or ventilator- associated pneumonia.

Association of liver dysfunction with outcomes after cardiac surgery-a meta-analysis. Interact Cardiovasc Thorac Surg 2022; 35:6883890. [PMID: 36477871 PMCID: PMC9741516 DOI: 10.1093/icvts/ivac280] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Accepted: 12/06/2022] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVES The aim of this study was to perform a meta-analysis of studies reporting outcomes in patients with liver dysfunction addressed by the model of end-stage liver disease and Child-Turcotte-Pugh scores undergoing cardiac surgery. METHODS A systematic literature search was conducted to identify contemporary studies reporting short- and long-term outcomes in patients with liver dysfunction compared to patients with no or mild liver dysfunction undergoing cardiac surgery (stratified in high and low score group based on the study cut-offs). Primary outcome was perioperative mortality. Secondary outcomes were perioperative neurological events, prolonged ventilation, sepsis, bleeding and/or need for transfusion, acute kidney injury and long-term mortality. RESULTS A total of 33 studies with 48 891 patients were included. Compared with the low score group, being in the high score group was associated with significantly higher risk of perioperative mortality [odds ratio (OR) 3.72, 95% confidence interval (CI) 2.75-5.03, P < 0.001]. High score group was also associated with a significantly higher rate of perioperative neurological events (OR 1.49, 95% CI 1.30-1.71, P < 0.001), prolonged ventilation (OR 2.45, 95% CI 1.94-3.09, P < 0.001), sepsis (OR 3.88, 95% CI 2.07-7.26, P < 0.001), bleeding and/or need for transfusion (OR 1.95, 95% CI 1.43-2.64, P < 0.001), acute kidney injury (OR 3.84, 95% CI 2.12-6.98, P < 0.001) and long-term mortality (incidence risk ratio 1.29, 95% CI 1.14-1.46, P < 0.001). CONCLUSIONS The analysis suggests that liver dysfunction in patients undergoing cardiac surgery is independently associated with higher risk of short and long-term mortality and also with an increased occurrence of various perioperative adverse events.

Intraoperative fluid balance and cardiac surgery-associated acute kidney injury: a multicenter prospective study. BRAZILIAN JOURNAL OF ANESTHESIOLOGY (ELSEVIER) 2022; 72:688-694. [PMID: 35917847 PMCID: PMC9659999 DOI: 10.1016/j.bjane.2022.07.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 07/20/2022] [Accepted: 07/24/2022] [Indexed: 05/16/2023]
Abstract
BACKGROUND Recent data suggest the regime of fluid therapy intraoperatively in patients undergoing major surgeries may interfere in patient outcomes. The development of postoperative Acute Kidney Injury (AKI) has been associated with both Restrictive Fluid Balance (RFB) and Liberal Fluid Balance (LFB) during non-cardiac surgery. In patients undergoing cardiac surgery, this influence remains unclear. The study objective was to evaluate the relationship between intraoperative RFB vs. LFB and the incidence of Cardiac-Surgery-Associated AKI (CSA-AKI) and major postoperative outcomes in patients undergoing on-pump Coronary Artery Bypass Grafting (CABG). METHODS This prospective, multicenter, observational cohort study was set at two high-complexity university hospitals in Brazil. Adult patients who required postoperative intensive care after undergoing elective on-pump CABG were allocated to two groups according to their intraoperative fluid strategy (RFB or LFB) with no intervention. RESULTS The primary endpoint was CSA-AKI. The secondary outcomes were in-hospital mortality, cardiovascular complications, ICU Length of Stay (ICU-LOS), and Hospital LOS (H-LOS). After propensity score matching, 180 patients remained in each group. There was no difference in risk of CSA-AKI between the two groups (RR = 1.15; 95% CI, 0.85-1.56, p = 0.36). The in-hospital mortality, H-LOS and cardiovascular complications were higher in the LFB group. ICU-LOS was not significantly different between the two groups. ROCcurve analysis determined a fluid balance above 2500 mL to accurately predict in-hospital mortality. CONCLUSION Patients undergoing on-pump CABG with LFB when compared with patients with RFB present similar CSA-AKI rates and ICU-LOS, but higher in-hospital mortality, cardiovascular complications, and H-LOS.

Diabetes Is an Independent Risk Factor for Cancer after Heart and/or Lung Transplantation. J Clin Med 2022; 11:jcm11144127. [PMID: 35887891 PMCID: PMC9323113 DOI: 10.3390/jcm11144127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 07/12/2022] [Accepted: 07/13/2022] [Indexed: 02/04/2023] Open
Abstract
Background: De novo cancers are feared complications after heart or lung transplantation. Recent data suggest that diabetes mellitus (DM) might also be a risk factor for cancer. We hypothesized that transplanted diabetic patients are at greater risk of developing cancer compared to non-diabetic ones. Methods: We reviewed 353 patients post-heart and/or -lung transplantation from our center between October 1999 and June 2021. Patients with follow-up <180 days (n = 87) were excluded from the analysis. The remaining 266 patients were divided into patients who had preoperative DM (n = 88) or developed it during follow-up (n = 40) and patients without DM (n = 138). Results: The diabetic cohort showed higher rates of malignancies in all patients (30.33 vs. 15.97%, p = 0.005) and in the matched population (31.9 vs. 16.1%, p < 0.001). There were also significantly more solid tumors (17.9 vs. 9.4%, p = 0.042; matched: 16.6 vs. 9.1%, p = 0.09) The presence of diabetes was associated with a 13% increased risk of cancer when compared to non-diabetic patients. New-onset post-transplant diabetes doubled the likelihood of cancer development. Conclusions: Pre-transplant diabetes mellitus increases the risk of cancer after heart and/or lung transplantation. However, new-onset diabetes after transplantation is associated with a much greater cancer risk. This information is relevant for screening during follow-up.

Abstract
PubMed displayed more than 35,000 hits for the search term "cardiac surgery AND 2021." We used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) approach and selected relevant publications for a results-oriented summary. As in recent years, we reviewed the fields of coronary and conventional valve surgery and their overlap with their interventional alternatives. COVID reduced cardiac surgical activity around the world. In the coronary field, the FAME 3 trial dominated publications by practically repeating SYNTAX, but with modern stents and fractional flow reserve (FFR)-guided percutaneous coronary interventions (PCIs). PCI was again unable to achieve non-inferiority compared with coronary artery bypass graft surgery (CABG) in patients with triple-vessel disease. Survival advantages of CABG over PCI could be linked to a reduction in myocardial infarctions and current terminology was criticized because the term "myocardial revascularization" is not precise and does not reflect the infarct-preventing collateralization effect of CABG. In structural heart disease, new guidelines were published, providing upgrades of interventional treatments of both aortic and mitral valve disease. While for aortic stenosis, transcatheter aortic valve implantation (TAVI) received a primary recommendation in older and high-risk patients; recommendations for transcatheter mitral edge-to-edge treatment were upgraded for patients considered inappropriate for surgery. For heart team discussions it is important to know that classic aortic valve replacement currently provides strong signals (from registry and randomized evidence) for a survival advantage over TAVI after 5 years. This article summarizes publications perceived as important by us. It can neither be complete nor free of individual interpretation, but provides up-to-date information for decision-making and patient information.

Treatment of valvular heart disease in young patients-"early evidence" versus "latest fashion". J Card Surg 2022; 37:2375-2377.

Abstract
Is the performance of locally manufactured mechanical valve prostheses relevant for modern cardiac surgery, in which mechanical valve replacement has become a rarity? This question comes to mind reading the article in this issue of the Journal demonstrating equal outcomes of the TTK Chitra tilting disk mechanical heart valve prostheses in comparison to the SJM bi-leaflet blockbuster. The evidence documenting efficacy of mechanical valve replacement stems from the early ages of cardiac surgery, but often demonstrates superior outcomes in terms of survival and hemodynamics. Yet, the latest fashion in the Western world consists biological choices in combination with new transcatheter techniques (valve in valve options) or the Ozaki or Ross procedures. As long-term results are often missing and documented advantages for mechanical valves stems from early evidence, the local emphasis of mechanical valve replacement may possibly result in superior individual prognoses compared to following the Western world's latest fashions. Individual patient information and decision making moves into focus.

Abstract WMP73: Surgical Timing In Infective Endocarditis Patients With Intracranial Hemorrhage -a Systematic Review And Meta-analysis. Stroke 2022. [DOI: 10.1161/str.53.suppl_1.wmp73] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
Background and Purpose:
Cardiac surgery is indicated in more than half of patients with infective endocarditis (IE); however, it is performed in only 60% of the indicated cases. Majority of patients with surgical indications who were denied surgery due to certain reasons die within 30 days. Intracranial hemorrhage (ICH) is one of the main causes for denial of surgery despite the presence of surgical indications. We aimed to evaluate the impact of early surgery (within 30 days) in IE-patients with ICH on postoperative outcome and to elucidate the risk of 30-day mortality in patients for whom surgery was denied.
Methods:
Three libraries (MEDLINE, EMBASE and Cochrane Library) were assessed for studies evaluating the postoperative outcome in early vs. late surgery in IE-patients with preoperative ICH. The primary outcome was all-cause mortality, and the secondary outcome was neurological deterioration. Inverse variance method and random model were performed.
Results:
We identified 16 studies including 355 patients. Nine studies examined the impact of surgical timing (early vs. late) and were included in the meta-analyses. Only one study examined the fate of IE-patients with ICH who were treated conservatively despite of having an indication for cardiac surgery, showing higher mortality rates than those who were operated (11.8 % vs. 2.5 %). We found no significant association between early surgery, regardless of its definition, and a higher mortality (relative risk [RR]= 1.46; 95% confidence interval [CI]: 0.98-2.17). However, early surgery was associated with higher risk for neurological deterioration (RR= 1.97; 95% CI: 1.15-3.38).
Conclusions:
Cardiac surgery for IE within 30 days of ICH was not associated with higher mortality, but with increased rate of neurological deterioration. Thirty-day mortality in IE-patients with ICH for whom surgery was denied has not yet been sufficiently investigated. This patient group should be analysed in future studies in more detail.

Neurocognitive decline in cardiac surgery-Distraction rather than destruction? J Card Surg 2021; 37:148-150. [PMID: 34669213 DOI: 10.1111/jocs.16099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Accepted: 10/15/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND A neurocognitive decline is an undesirable event that can be observed in patients after cardiac surgery. It has been related to the use of cardiopulmonary bypass (CPB). Minor embolic or hyperinflammatory mechanisms are thought to be responsible. In this issue of the Journal of Cardiac Surgery, the neurocognitive decline was observed in 22 of 30 patients after cardiac surgery with CPB. Repeatable neuropsychological status tests were used and scores 4 days after surgery were 5%-15% lower than before. Mechanistic investigations with glycemic control and transcriptomic and cytokine analyses failed to provide an explanation but the frequency of this observation is worrisome. DISCUSSION However, available evidence suggests that neurocognitive dysfunction disappears within a few months, and later on no difference to controls that did not undergo surgery can be detected. In addition, similar degrees of neurocognitive dysfunction can be observed after noncardiac surgery and even after percutaneous coronary intervention (PCI). A most recent comparison of memory decline after CABG and PCI also suggests no difference between the two invasive treatment options for coronary artery disease. All these findings argue against a primarily CPB-associated mechanism. Interestingly, test subjects from a consumer investigation showed a 10% decline in their working memory just by placing their cell phone on the table, suggesting that being distracted may also affect neurocognitive function. Given the reversibility of surgery- and intervention-associated neurocognitive dysfunction, we question destructive, embolic, or inflammatory-associated mechanisms. Distractive aspects of intervention-associated stress may also play a role. CONCLUSION In any case, neurocognitive decline after cardiac surgery does not appear to be surgery-specific.

Abstract
In 2020, nearly 30,000 published references appeared in the PubMed for the search term "cardiac surgery." While SARS-CoV-2 affected the number of surgical procedures, it did not affect outcomes reporting. Using the PRISMA approach, we selected relevant publications and prepared a results-oriented summary. We reviewed primarily the fields of coronary and conventional valve surgery and their overlap with interventional alternatives. The coronary field started with a discussion on trial data value and their interpretation. Registry comparisons of coronary artery bypass surgery (CABG) and percutaneous coronary intervention confirmed outcomes for severe coronary artery disease and advanced comorbidities with CABG. Multiple arterial grafting was best. In aortic valve surgery, meta-analyses of randomized trials report that transcatheter aortic valve implantation may provide a short-term advantage but long-term survival may be better with classic aortic valve replacement (AVR). Minimally invasive AVR and decellularized homografts emerged as hopeful techniques. In mitral and tricuspid valve surgery, excellent perioperative and long-term outcomes were presented for structural mitral regurgitation. For both, coronary and valve surgery, outcomes are strongly dependent on surgeon expertise. Kidney disease increases perioperative risk, but does not limit the surgical treatment effect. Finally, a cursory look is thrown on aortic, transplant, and assist-device surgery with a glimpse into the current stand of xenotransplantation. As in recent years, this article summarizes publications perceived as important by us. It does not expect to be complete and cannot be free of individual interpretation. We aimed to provide up-to-date information for decision-making and patient information.
