RESUMEN
There is debate on the best treatment for significant stenoses of the left main (LM) coronary artery. The available evidence is based on four randomized trials, which were either performed specifically to assess patients with LM disease (EXCEL, NOBLE, PRECOMBAT) or had a significant fraction of patients with this disease pattern (SYNTAX). A meta-analysis revealed no difference in periprocedural and 5-year mortality but demonstrated a significant reduction of spontaneous myocardial infarction (MI) with CABG. Furthermore, the recently published SWEDEHEART registry data have shown survival advantage and fewer MACCE with CABG for LM disease after adjustment. In general, patients with more severe coronary artery disease (CAD) appear to have a survival advantage with CABG both over PCI and medical therapy (independent of the presence or absence of LM stenosis), which is always associated with a reduction of spontaneous MI in the CABG arm. Since the nomenclature of LM disease does not automatically reflect the complexity of CAD, we review the nature of LM disease in this article. We mechanistically assess the treatment effects of PCI and CABG for patients with LM disease, which is rarely isolated, often distal, and mostly associated with varying degrees of single and multi-vessel disease. We conclude that in patients with isolated LM shaft lesions and associated diseases of low complexity, the risk of spontaneous MI is lower, and PCI may achieve similar long-term outcomes compared to CABG. Thus, heart teams are essential for selecting the best treatment option and should focus on assessing infarction risk in chronic CAD.
RESUMEN
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.
RESUMEN
Background: Antithrombotic therapy (ATT) in patients with infective endocarditis (IE) is challenging. Objectives: The authors evaluated the impact of anticoagulant and antiplatelet therapy on clinical endpoints in IE patients. Methods: We performed a systematic review and meta-analysis comparing IE patients with prior and/or ongoing use of ATT vs those without any ATT during IE course. Primary outcome was reported in-hospital cerebrovascular events. Secondary outcomes were in-hospital mortality, intracranial hemorrhage (ICH), systemic thromboembolism (ST), and mortality within 6 months. Results: Twelve studies, with a total of 12,151 patients, were included. The primary endpoint was not different comparing 10,115 IE patients with or without prior anticoagulation (OR: 1.10; 95% CI: 0.56-2.17; P = 0.77) or comparing 838 IE patients with or without prior antiplatelet (OR: 0.90; 95% CI: 0.61-1.33; P = 0.61). In-hospital mortality was lower in IE patients with prior anticoagulation compared to those without (OR: 0.74; 95% CI: 0.57-0.96; P = 0.03). There was no difference in reported ICH rates between patients with or without prior anticoagulation (OR: 0.54; 95% CI: 0.27-1.09; P = 0.09) or between patients with or without prior antiplatelet (OR: 0.35; 95% CI: 0.11-1.10; P = 0.07). The rate of ST was lower in IE patients with prior antiplatelet therapy compared to those without (OR: 0.53; 95% CI: 0.38-0.72; P < 0.01). Conclusions: ATT in IE patients was not associated with higher frequency of cerebrovascular events or ICH. Moreover, we found that the use of anticoagulation was associated with decreased in-hospital mortality and the use of antiplatelets was associated with decreased ST. Due to the limitations of this study, these results should be interpreted cautiously showing the necessity of a randomized setup.
RESUMEN
BACKGROUND: Postoperative bleeding requiring re-exploration is a serious complication that occurs in 2.8% to 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: We 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% confidence interval [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 [MD]: 2.69, 95% CI, 1.68 to 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- and long-term outcomes, strategies to prevent the need for re-exploration are necessary.
RESUMEN
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.

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.

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.

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.

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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.

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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
