RESUMO
Liver transplantation (LT) is the second most performed solid organ transplant. Coronary artery disease (CAD) is a critical consideration for LT candidacy, particularly in patients with known CAD or risk factors, including metabolic dysfunction associated with steatotic liver disease. The presence of severe CAD may exclude patients from LT; therefore, precise preoperative evaluation and interventions are necessary to achieve transplant candidacy. Cardiovascular complications represent the earliest nongraft-related cause of death post-transplantation. Timely intervention to reduce cardiovascular events depends on adequate CAD screening. Coronary disease screening in end-stage liver disease is challenging because standard noninvasive CAD screening tests have low sensitivity due to hyperdynamic state and vasodilatation. As a result, there is overuse of invasive coronary angiography to exclude severe CAD. Coronary artery calcium scoring using a computed tomography scan is a tool for the prediction of cardiovascular events, and can be used to achieve risk stratification in LT candidates. Recent literature shows that qualitative assessment on both noncontrast- and contrast-enhanced chest computed tomography can be used instead of calcium score to assess the presence of coronary calcium. With increasing prevalence, protocols to address CAD in LT candidates must be reconsidered. Percutaneous coronary intervention could allow a shorter duration of dual-antiplatelet therapy in simple lesions, with safer perioperative outcomes. Hybrid coronary revascularization is an option for high-risk LT candidates with multivessel disease nonamenable to percutaneous coronary intervention. The objective of this review is to evaluate existing methods for preoperative cardiovascular risk stratification, and to describe interventions before surgery to optimize patient outcomes and reduce cardiovascular event risk.

BACKGROUND: Clinical and anatomical characteristics are often considered key factors in deciding between percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in patients with complex coronary artery disease (CAD) such as left-main CAD or 3-vessel disease. However, little is known about the interaction between self-reported preprocedural physical/mental health and clinical outcomes after revascularization. METHODS: This subgroup analysis of the SYNTAXES trial (SYNTAX Extended Survival), which is the extended follow-up of the randomized SYNTAX trial (Synergy Between PCI With Taxus and Cardiac Surgery) comparing PCI with CABG in patients with left-main CAD or 3-vessel disease, stratified patients by terciles of Physical (PCS) or Mental Component Summary (MCS) scores derived from the preprocedural 36-Item Short Form Health Survey, with higher PCS and MCS scores representing better physical and mental health, respectively. The primary end point was all-cause death at 10 years. RESULTS: A total of 1656 patients with preprocedural 36-Item Short Form Health Survey data were included in the present study. Both higher PCS and MCS were independently associated with lower 10-year mortality (10-point increase in PCS adjusted hazard ratio, 0.84 [95% CI, 0.73-0.97]; P=0.021; in MCS adjusted hazard ratio, 0.85 [95% CI, 0.76-0.95]; P=0.005). A significant survival benefit with CABG over PCI was observed in the highest PCS (>45.5) and MCS (>52.3) terciles with significant treatment-by-subgroup interactions (PCS Pinteraction=0.033, MCS Pinteraction=0.015). In patients with both high PCS (>45.5) and MCS (>52.3), 10-year mortality was significantly higher with PCI compared with CABG (30.5% versus 12.2%; hazard ratio, 2.87 [95% CI, 1.55-5.30]; P=0.001), whereas among those with low PCS (≤45.5) or low MCS (≤52.3), there were no significant differences in 10-year mortality between PCI and CABG, resulting in a significant treatment-by-subgroup interaction (Pinteraction=0.002). CONCLUSIONS: Among patients with left-main CAD or 3-vessel disease, patient-reported preprocedural physical and mental health status was strongly associated with long-term mortality and modified the relative treatment effects of PCI versus CABG. Patients with the best physical and mental health had better 10-year survival with CABG compared with PCI. Assessment of self-reported physical and mental health is important when selecting the optimal revascularization strategy. REGISTRATION: URL: https://www.

AIM: The aim of this study was to compare long-term all-cause mortality between patients receiving percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) using multiple (MAG) or single arterial grafting (SAG). METHODS AND RESULTS: The current study is a post hoc analysis of the SYNTAX Extended Survival Study, which compared PCI with CABG in patients with three-vessel (3VD) and/or left main coronary artery disease (LMCAD) and evaluated survival with ≥10 years of follow-up. The primary endpoint was all-cause mortality at maximum follow-up (median 11.9 years) assessed in the as-treated population. Of the 1743 patients, 901 (51.7%) underwent PCI, 532 (30.5%) received SAG, and 310 (17.8%) had MAG. At maximum follow-up, all-cause death occurred in 305 (33.9%), 175 (32.9%), and 70 (22.6%) patients in the PCI, SAG, and MAG groups, respectively (P < 0.001). Multiple arterial grafting [adjusted hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.49-0.89], but not SAG (adjusted HR 0.83, 95% CI 0.67-1.03), was associated with significantly lower all-cause mortality compared with PCI. In patients with 3VD, both MAG (adjusted HR 0.55, 95% CI 0.37-0.81) and SAG (adjusted HR 0.68, 95% CI 0.50-0.91) were associated with significantly lower mortality than PCI, whereas in LMCAD patients, no significant differences between PCI and MAG (adjusted HR 0.90, 95% CI 0.56-1.46) or SAG (adjusted HR 1.11, 95% CI 0.81-1.53) were observed. In patients with revascularization of all three major myocardial territories, a positive correlation was observed between the number of myocardial territories receiving arterial grafts and survival (Ptrend = 0.003). CONCLUSION: Our findings suggest that MAG might be the more desirable configuration for CABG to achieve lower long-term all-cause mortality than PCI in patients with 3VD and/or LMCAD.

AIMS: The aim of this article was to compare rates of all-cause death at 10 years following coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in patients with or without diabetes. METHODS AND RESULTS: The SYNTAXES study evaluated up to 10-year survival of 1800 patients with three-vessel disease (3VD) and/or left main coronary artery disease (LMCAD) randomized to receive either PCI or CABG in the SYNTAX trial. Ten-year all-cause death according to diabetic status and revascularization strategy was examined. In diabetics (n = 452), the risk of mortality was numerically higher with PCI compared with CABG at 5 years [19.6% vs. 13.3%, hazard ratio (HR): 1.53, 95% confidence interval (CI): 0.96, 2.43, P = 0.075], with the opposite seen between 5 and 10 years (PCI vs. CABG: 20.8% vs. 24.4%, HR: 0.82, 95% CI: 0.52, 1.27, P = 0.366). Irrespective of diabetic status, there was no significant difference in all-cause death at 10 years between patients receiving PCI or CABG, the absolute treatment difference was 1.9% in diabetics (PCI vs. CABG: 36.4% vs. 34.5%, difference: 1.9%, 95% CI: -7.6%, 11.1%, P = 0.551). Among insulin-treated patients (n = 182), all-cause death at 10 years was numerically higher with PCI (47.9% vs. 39.6%, difference: 8.2%, 95% CI: -6.5%, 22.5%, P = 0.227). CONCLUSIONS: The treatment effects of PCI vs. CABG on all-cause death at 10 years in patients with 3VD and/or LMCAD were similar irrespective of the presence of diabetes. There may, however, be a survival benefit with CABG in patients with insulin-treated diabetes. The association between revascularization strategy and very long-term ischaemic and safety outcomes for patients with diabetes needs further investigation in dedicated trials.

OBJECTIVES: We investigated the impact of total stent length (TSL) and average nominal stent diameter (ASD) on 10-year mortality after percutaneous coronary intervention (PCI) in the SYNTAXES trial. BACKGROUND: TSL and ASD in patients treated with PCI are associated with major adverse cardiovascular events. However, the treatment effect of PCI with extensive and/or small stenting as compared with coronary artery bypass grafting (CABG) for complex coronary artery disease has not been fully evaluated. METHODS: Impacts on mortality of extensive stenting defined as TSL >100 mm and small stenting as ASD <3 mm were analyzed in 893 PCI patients and were compared to 865 CABG patients. RESULTS: TSL as a continuous variable was significantly associated with 10-year mortality (adjusted hazard ratio [HR], 1.05 [1.01-1.09] per 10 mm increase). PCI patients with extensive stenting had a higher 10 year mortality than CABG patients (adjusted HR, 1.97 [1.41-2.74]) or not- extensive stenting PCI (adjusted HR, 1.94 [1.36-2.77]). Although ASD did not have a significant association with 10 year mortality (adjusted HR, 0.97 [0.85-1.11] per 0.25 mm increase), PCI with small stents was associated with a higher 10 year mortality, compared to CABG (adjusted HR, 1.66 [1.23-2.26]) and PCI performed with large stents (adjusted HR, 1.74 [1.19-2.53]). Patients treated with not-extensive and large stents had similar mortality rates (24.0 versus 23.8%) as those treated with CABG. CONCLUSIONS: Extensive and small stenting were associated with higher 10 year mortality, compared with CABG. When patients have to be treated with extensive or small stenting, revascularization with CABG should be preferred.

BACKGROUND: Cardiogenic shock after acute myocardial infarction is an indication for emergent coronary artery bypass grafting in patients not amenable to percutaneous coronary intervention. Our study aimed to evaluate and identify risk factors for early and long-term outcomes in such patients. METHODS: A total of 508 patients who underwent coronary artery bypass grafting for cardiogenic shock complicating acute myocardial infarction between January 2000 and June 2014 were divided into 3 time cohorts: 2000 to 2004 (n=204), 2005 to 2009 (n=166), and 2010 to 2014 (n=138). Predictors of in-hospital mortality for each time cohort and long-term mortality for all patients were identified by logistic and Cox regression analyses, respectively. RESULTS: Mean age was 68.3±9.8 years. Of the 508 patients, 78.5% had 3-vessel and 47.1% had left main disease. Left ventricular function <30% was observed in 44.1% of patients, with 30.4%, 37.9%, 52.9%, and 3.1% requiring preoperative resuscitation, ventilation, intra-aortic balloon pump, and extracorporeal membrane oxygenation support, respectively. Overall in-hospital mortality was 33.7%; declined from 42.2% to 30.7% to 24.6%, respectively, for the 3 time cohorts (P=0.02); and was independently predicted by serum lactate >4 mmol/L (odds ratio [OR], 4.78; 95% confidence interval, 2.88-7.95; P<0.0001), ST-segment-elevation myocardial infarction (OR, 2.10; 95% confidence interval, 1.36-3.26; P=0.001), age >75 years (OR, 2.01; 95% confidence interval, 1.06-3.85; P=0.03), and left ventricular ejection fraction <30% (OR, 1.83; 95% confidence interval, 1.15-2.91; P=0.01). Cumulative survival was 42.6±2.0% and 33.4±2.0% at 5 and 10 years, respectively, and correspondingly improved to 64.3±3.0% and 49.8±3.0% in hospital survivors. Serum lactate >4 mmol/L (OR, 2.2; P<0.0001), incremental age (OR, 1.05; P<0.0001), New York Heart Association class IV (OR, 1.33; P=0.02), diabetes mellitus (OR, 1.39; P=0.005), and preoperative inotropic (OR, 2.61; P=0.001) and extracorporeal membrane oxygenation (OR, 1.68; P=0.05) support predicted late mortality. CONCLUSIONS: Emergency coronary artery bypass grafting in patients with acute myocardial infarction complicated by cardiogenic shock is associated with a high in-hospital mortality, which showed a significant decline with time. Hospital survivors have good long-term outcomes, which demonstrate the beneficial effect of surgical revascularization. Preoperative serum lactate >4 mmol/L is a strong predictor of both early and late mortality.

Objective In the present study, we retrospectively identified and analyzed the factors that influenced progressive dilatation of the residual distal aorta after surgical repair for acute type A aortic dissection (acute type A). Methods A total of 477 patients underwent surgical repair for acute type A aortic dissection between 1995 and 2012. Postoperative and follow-up computed tomography (CT) scans of the descending aorta were available in 105 patients. We analyzed the maximum aortic diameter, total luminal area, and true luminal area of the descending thoracic and abdominal aorta. Results The mean follow-up time was 4.5 ± 3 years, and the mean time interval between CT scan investigations was 2.0 ± 2.3 years. A residual dissection membrane was observed in 80 (76%) patients, with presence of a patent false lumen (FL) in 52 patients (50%) and a thrombosed FL in 28 patients (26%).Progression of aortic disease with an increase in aortic diameter greater than 10 mm was observed in 14.3% (n = 15) of patients during follow-up. The independent predictors that influenced progressive dilation of the descending aorta by 10 mm or more were postoperative descending aortic diameter greater than 40 mm (p = 0.006; odds ratio [OR], 5.6; 95% confidence interval [CI], 1.6-19) and postoperative patent FL (p = 0.002; OR, 8.5; 95% CI, 2.2-32.3).The unadjusted 1- and 5-year freedom from reoperation was 96.9 ± 2 and 80.1 ± 5%, respectively. Marfan syndrome (p = 0.006; OR, 5.2; 95% CI, 1.6-16.9) and postoperative descending aortic diameter greater than 40 mm (p = 0.07; OR, 4.1; 95% CI, 1.4-11.6) were independent predictors of aorta-related reoperations.The mean survival at 1, 5, and 8 years was 90.7 ± 3, 82.5 ± 4, and 70 ± 6%, respectively. Previous cardiac surgery was independent predictor of midterm survival (hazard ratio, 3.6; 95% CI, 1.03-2.8; p = 0.04). Conclusions A regular follow-up CT scan is mandatory to assess progressive dilatation of the distal residual aortic arch, descending thoracic, and abdominal aorta after surgical repair of acute type A dissection, particularly in patients with a patent FL, descending aortic diameter greater than 40 mm, and/or Marfan syndrome.

BACKGROUND: Current guidelines do not provide recommendations for optimal timing of coronary artery bypass surgery (CABG) in patients with non-ST-segment-elevation myocardial infarction. Our study aimed to determine the impact of CABG timing on early and late outcomes in patients with non-ST-segment-elevation myocardial infarction. METHODS AND RESULTS: A total of 758 patients underwent CABG within 21 days after non-ST-segment-elevation myocardial infarction between January 2008 and December 2012 at our institution. The patients were divided into 3 groups according to the time interval between symptom onset and CABG: group A, <24 hours (133 patients); group B, 24 to 72 hours (192 patients); and group C, >72 hours to 21 days (433 patients). Predictors of in-hospital and long-term mortality were identified by logistic and Cox regression analyses, respectively. Overall in-hospital mortality was 5.1% (39 patients): 6.0%, 4.7%, and 5.1% in groups A, B, and C (P=0.9), respectively. A total of 118 patients died during follow-up. The 5-year survival was 73.1±2%, with a nonsignificant trend toward better survival in groups A (78.2±4%) and C (75.4±3%) compared with group B (63.6±5%; log-rank P=0.06). Renal insufficiency and LMD were independent predictors of in-hospital (odds ratio, 3.1; P=0.001; and odds ratio, 3.1; P=0.002) and long-term mortality (hazard ratio, 1.7; P=0.004; and hazard ratio, 1.5; P=0.02), whereas administration of P2Y12 inhibitors was protective (odds ratio, 0.3; P=0.01). CONCLUSIONS: Emergent CABG within 24 hours of non-ST-segment-elevation myocardial infarction is associated with in-hospital mortality and long-term outcomes similar to those of CABG performed after 3 days, despite a higher risk profile. CABG performed between 24 to 72 hours showed a nonsignificant trend toward poorer long-term outcomes. Dual antiplatelet therapy until surgery is beneficial, whereas renal insufficiency and left main disease increase the risk of early and late death.

AIMS: Coronary artery bypass grafting (CABG) has been considered the standard of care for patients with three-vessel disease (3VD), but long-term comparative results from randomized trials of CABG vs. percutaneous coronary intervention (PCI) using drug-eluting stents (DES) remain limited. METHODS AND RESULTS: Patients with de novo 3VD or left main disease were randomly assigned to PCI with the paclitaxel-eluting first-generation stent or CABG in the SYNTAX trial. This pre-specified analysis presents the 5-year outcomes of patients with 3VD (n = 1095). The rate of major adverse cardiac and cerebrovascular events (MACCE) was significantly higher in patients with PCI compared with CABG (37.5 vs. 24.2%, respectively; P < 0.001). Percutaneous coronary intervention as opposed to CABG resulted in significantly higher rates of the composite of death/stroke/myocardial infarction (MI) (22.0 vs. 14.0%, respectively; P < 0.001), all-cause death (14.6 vs. 9.2%, respectively; P = 0.006), MI (9.2 vs. 4.0%, respectively; P = 0.001), and repeat revascularization (25.4 vs. 12.6%, respectively; P < 0.001); however, stroke was similar between groups at 5 years (3.0 vs. 3.5%, respectively; P = 0.66). Results were dependent on lesion complexity (P for interaction = 0.12); in patients with a low (0-22) SYNTAX score, PCI vs. CABG resulted in similar rates of MACCE (33.3% vs. 26.8%, respectively; P = 0.21) but significantly more repeat revascularization (25.4% vs. 12.6%, respectively; P = 0.038), while in intermediate (23-32) or high (≥ 33) SYNTAX score terciles, CABG demonstrated clear superiority in terms of MACCE, death, MI, and repeat revascularization. Differences in MACCE between PCI and CABG were larger in diabetics [hazard ratio (HR) = 2.30] than non-diabetics (HR = 1.51), although the P for interaction failed to reach significance for MACCE (P for interaction = 0.095) or any of the other endpoints. CONCLUSION: Five-year results of patients with 3VD treated with CABG or PCI using the first-generation paclitaxel-eluting DES suggest that CABG should remain the standard of care as it resulted in significantly lower rates of death, MI, and repeat revascularization, while stroke rates were similar. For patients with low SYNTAX scores, PCI is an acceptable revascularization strategy, although at a price of significantly higher rates of repeat revascularization.

BACKGROUND: To analyze the effect of immediate treatment of perioperative myocardial ischemia (PMI) because of early graft failure or incomplete revascularization in patients undergoing coronary artery bypass grafting (CABG) surgery. METHODS AND RESULTS: Between January 2004 and December 2010, 7461 patients underwent isolated CABG at our institution. All patients showing evidence of PMI (n=399; 5.3% of total) underwent emergent coronary angiography. A total of 900 grafts and 1061 distal anastomoses were examined. Two hundred fifty-five patients had 360 distal anastomoses compromised because of early graft failure or incomplete revascularization (ie, abnormal postoperative coronary angiogram). Revision CABG or percutaneous coronary intervention was performed in 130 (51.0%) and 34 (13.3%) patients with abnormal angiograms, respectively. Nonsurgical therapy was implemented in the remaining 91 patients (35.7%) with abnormal angiograms. One hundred forty-four patients had normal postoperative graft-related angiograms. In-hospital mortality was 7.3% and 2.9% in patients with and without PMI (P<0.001). In patients with PMI, in-hospital mortality was 9.4% and 3.5% in patients with abnormal and normal postoperative angiograms, respectively (P=0.03). Significant multivariable predictors of in-hospital mortality were hemodynamic deterioration, preangiography creatine kinase-MB isoenzyme rise >2 × normal, and time interval between primary CABG and coronary angiography >30 hours. Five-year survival in patients without PMI (85.7 ± 0.5%) was significantly better than those with PMI and abnormal angiograms (74.9 ± 2.9%; P<0.001 log-rank). When in-hospital mortality was excluded, however, this difference in midterm survival disappeared (P=0.9). CONCLUSIONS: PMI is associated with increased in-hospital mortality in patients undergoing isolated CABG. Expeditious management of bypass graft failure results in similar midterm survival to nonischemic patients in hospital survivors.

New-generation stents have been continually developed in order to improve the safety and efficacy of percutaneous coronary intervention (PCI). Several randomized clinical trials have been conducted over the last two decades to compare the outcomes of PCI with coronary artery bypass grafting (CABG), which has been the time-tested treatment of multivessel coronary artery disease. The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) trial is one of the most recent and largest randomized controlled trials comparing PCI using the paclitaxel-eluting first-generation stent with CABG and was uniquely formulated to represent "real world" daily practice. The final 5-year main results of this trial and its various prespecified subgroups have been published in the past year. These results will form the basis of the new guidelines that will be published in the near future. This review is a compilation of the results of the SYNTAX trial and comparisons with other contemporary trials, meta-analyses, and retrospective studies of large registries and how these results help cardiac surgeons and cardiologists in judicious decision-making for their patients with multivessel coronary artery disease requiring revascularization.

BACKGROUND: Total arterial revascularization is associated with superior outcomes to conventional coronary artery bypass graft (CABG) surgery performed with the left internal thoracic artery (ITA) and veins. It is often performed with bilateral ITAs that increase risk of sternal wound infection. Minimally invasive multivessel CABG via a left anterior mini-thoracotomy eliminates sternal wound complications. However, being performed only in a few specialized centers, there is a paucity in follow-up outcome data. We, therefore, describe our five-year single-center experience with such operations. METHODS: A total of 186 patients underwent elective, total arterial minimally invasive CABG in our institution between 2015 and 2021. Patient data were prospectively collected via the institutional database and retrospectively analyzed. Primary endpoints were in-hospital mortality and five-year survival. The secondary endpoints included freedom from major adverse cerebrovascular and cardiac events. RESULTS: The mean age of patients was 66±9 years, with 23(12%) being female. The mean number of bypass grafts performed was 2.4±0.5(range: 2-4). Bilateral ITAs were used in 163(88%) and left ITA and radial arteries in 22(12%) patients. The mean procedure time was 277±58 minutes. There was 1 hospital death. Perioperative myocardial infarction, re-thoracotomy, and conversion to sternotomy was observed in 6(3%), 12(6,5%) and 2(1.1%) patients, respectively. The mean five-year survival was 93.3±2.2% and freedom from major adverse cardiac and cerebrovascular events was 83.8±4.1%. CONCLUSIONS: Total arterial minimally invasive CABG is a feasible surgical approach yielding excellent short and mid-term results, when performed in selected patients in specialized high-volume cardiac centers.
RESUMO
BACKGROUNDS: The impact of reduced left ventricular ejection fraction (LVEF) on very long-term prognosis following percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) has been debated. The aim of this study was to investigate the impact of LVEF at baseline on 10-year mortality in the SYNTAX trial. METHODS: Patients (n = 1800) were categorized into three sub-groups: reduced (rEF ≤ 40 %), mildly reduced (mrEF 41-49 %), and preserved LVEF (pEF ≥ 50 %). The SYNTAX score 2020 (SS-2020) was applied in patients with LVEF<50 % and ≥ 50 %. RESULTS: Ten-year mortalities were 44.0 %, 31.8 %, and 22.6 % (P < 0.001) in patients with rEF (n = 168), mrEF (n = 179), and pEF (n = 1453). Although no significant differences were observed, the mortality with PCI was higher than with CABG in patients with rEF (52.9 % vs 39.6 %, P = 0.054) and mrEF (36.0 % vs. 28.6 %, P = 0.273), and comparable in pEF (23.9 % vs. 22.2 %, P = 0.275). Calibration and discrimination of the SS-2020 in patients with LVEF<50 % were poor, whilst they were reasonable in those with LVEF≥50 %. The proportion of patients eligible for PCI who had a predicted equipoise in mortality with CABG was estimated to be 57.5 % in patients with LVEF≥50 %. CABG was safer than PCI in 62.2 % of patients with LVEF<50 %. CONCLUSIONS: Reduced LVEF was associated with an increased risk of 10-year mortality in patients revascularized either surgically or percutaneously. Compared to PCI, CABG was safe revascularization in patients with LVEF≤40 %. In patients with LVEF≥50 % individualized 10-year all-cause mortality predicted by SS-2020 was helpful in decision-making whilst the predictivity in patients with LVEF<50 % was poor.

BACKGROUND: Recently, machine learning algorithms have identified preprocedural γ-glutamyl transferase (GGT) as a significant predictor of long-term mortality after coronary revascularization in the SYNTAX (Synergy Between PCI [Percutaneous Coronary Intervention] With Taxus and Cardiac Surgery) trial. The aim of the present study is to investigate the impact of preprocedural GGT on 10-year all-cause mortality in patients with complex coronary artery disease after revascularization. METHODS AND RESULTS: The SYNTAX trial was a randomized trial comparing PCI with coronary artery bypass grafting in 1800 patients with complex coronary artery disease. The present report is a post hoc subanalysis of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) trial, an investigator-driven extended 10-year follow-up of the SYNTAX trial. The association between preprocedural GGT and 10-year all-cause mortality was investigated. The mean values of GGT for men and women were 43.5 (SD, 48.5) and 36.4 (SD, 46.1) U/L, respectively. In multivariable Cox regression models adjusted by traditional risk factors, GGT was an independent predictor for all-cause death at 10-year follow-up, and each SD increase in log-GGT was associated with a 1.24-fold risk of all cause death at 10-year follow-up (95% CI, 1.10-1.40). According to previously reported sex-related GGT thresholds, patients with higher GGT level had a 1.74-fold risk of all-cause death at 10-year follow-up (95% CI, 1.32-2.29) compared with patients with lower GGT level. CONCLUSIONS: Preprocedural GGT is an independent predictor of 10-year mortality after coronary revascularization in patients with complex coronary artery disease. In patients with elevated GGT, strong secondary prevention may be required after revascularization and must be studied prospectively. REGISTRATION: URL: https://clinicaltrials.gov/study/NCT03417050.

OBJECTIVE: Minimally invasive direct coronary artery bypass (MIDCAB) surgery involving left anterior descending coronary artery grafting with the left internal thoracic artery through a left anterior small thoracotomy is being routinely performed in some specified centers for patients with isolated complex left anterior descending coronary artery disease, but very few reports regarding long-term outcomes exist in literature. Our study was aimed at assessing and analyzing the early and long-term outcomes of a large cohort of patients who underwent MIDCAB procedures and identifying the effects of changing trends in patient characteristics on early mortality. METHODS: A total of 2667 patients, who underwent MIDCAB procedures between 1996 and 2018, were divided into 3 groups on the basis of the year of surgery: group A, 1996-2003 (n = 1333); group B, 2004-2010 (n = 627) and group C, 2011-2018 (n = 707). Groupwise characteristics and early postoperative outcomes were compared. Long-term survival for all patients was analyzed and predictors for late mortality were identified using Cox proportional hazards methods. RESULTS: The mean age was 64.5 ± 10.9 years and 691 (25.9%) patients were female. Group C patients (log EuroSCORE I = 4.9 ± 6.9) were older with more cardiac risk factors and comorbidities than groups A (log EuroSCORE I = 3.1 ± 4.5) and B (log EuroSCORE I = 3.5 ± 4.7). Overall and groupwise in-hospital mortality was 0.9%, 1.0%, 0.6%, and 1.0% (P = .7), respectively. Overall 10-, 15-, and 20-year survival estimates for all patients were 77.7 ± 0.9%, 66.1 ± 1.2%, and 55.6 ± 1.6%, respectively. CONCLUSIONS: MIDCAB can be safely performed with very good early and long-term outcomes. In-hospital mortality remained constant over the 22-year period of the study despite worsening demographic profile of patients.

OBJECTIVES: The very long-term mortality of off-pump and on-pump coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) in a randomized complex coronary artery disease population is unknown. This study aims to investigate the impact of on-pump and off-pump CABG versus PCI on 10-year all-cause mortality. METHODS: The SYNTAX trial randomized 1800 patients with three-vessel and/or left main coronary artery disease to PCI or CABG and assessed their survival at 10 years. In this sub-study, the hazard of mortality over 10 years was compared according to the technique of revascularization: on-pump CABG (n = 725), off-pump CABG (n = 128) and PCI (n = 903). RESULTS: There was substantial inter-site variation in the use of off-pump CABG despite baseline characteristics being largely homogeneous among the 3 groups. The crude rate of mortality was significantly lower following on-pump CABG versus PCI [25.6% vs 28.4%, hazard ratio (HR) 0.79, 95% confidence interval (CI) 0.65-0.96], while it was comparable between off-pump CABG and PCI (28.5% vs 28.4%, HR 0.98, 95% CI 0.69-1.40). After adjusting for the 9 variables included in the SYNTAX score II 2020, 10-year mortality remained significantly lower with on-pump CABG than PCI (HR 0.75 against PCI, P = 0.009). CONCLUSIONS: In the SYNTAXES trial, 10-year mortality adjusted for major confounders was significantly lower following on-pump CABG compared to PCI. There was no evidence for unadjusted difference between off-pump CABG and PCI, although the unadjusted estimated HR had a wide CI. Site heterogeneity in the technique used in bypass surgery has had measurable effects on treatment performance.

OBJECTIVES: Perivalvular abscesses with destruction of the aortomitral junction (AMJ) are a severe complication of infective endocarditis (IE) and are associated with high mortality and complex management. The Hemi-Commando procedure is a mitral valve-sparing alternative to the Commando procedure in suitable patients with complex IE and paravalvular destruction. This study reviews the mid-term outcomes in patients undergoing the Hemi-Commando procedure for treating IE with destruction of the AMJ. METHODS: The clinical outcomes of patients with IE and AMJ involvement who underwent the Hemi-Commando procedure between 2015 and 2021 at the Leipzig Heart Center were retrospectively analysed. Primary outcomes were 30-day mortality and 1-year survival. Secondary outcome was 1-year freedom from reoperation. RESULTS: A total of 22 patients underwent the Hemi-Commando procedure during the study period. The patients' mean age was 59.8 ± 18.3 years. The study population was predominantly male (86.4%). Preoperative sepsis was present in 6 (27.3%) patients, and the median EuroSCORE II was 28.5%. Almost two-thirds (N = 14; 63.6%) of the patients presented with native IE. Streptococci were the most common pathogens (N = 8; 36.4%). Paravalvular abscess was found intraoperatively in 16 (72.7%) patients. The 30-day mortality was 13.6%. The estimated 1- and 3-year survival rates were 77.5% and 66.4%, respectively. The estimated freedom from reoperation at 1 and 3 years was 92.3%. CONCLUSIONS: The Hemi-Commando procedure offers an acceptable mid-term survival chance with low reoperation rates and is, therefore, a reasonable mitral valve-sparing alternative to the Commando procedure in suitable patients with extensive IE and perivalvular involvement.

AIMS: The aim of this study was to investigate the impact on 10-year survival of patient-reported anginal status at 1 year following percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in patients with left main coronary artery disease (LMCAD) and/or three-vessel CAD (3VD). METHODS AND RESULTS: In this post hoc analysis of the randomized SYNTAX Extended Survival study, patients were classified as having residual angina (RA) if their self-reported Seattle Angina Questionnaire angina frequency (SAQ-AF) scale was ≤90 at the 1-year follow-up post-revascularization with PCI or CABG. The primary endpoint of all-cause death at 10 years was compared between the RA and no-RA groups. A sensitivity analysis was performed using a 6-month SAQ-AF.At 1 year, 373 (26.1%) out of 1428 patients reported RA. Whilst RA at 1 year was an independent correlate of repeat revascularization at 5 years [18.3 vs. 11.5%; adjusted hazard ratio (HR): 1.54; 95% confidence interval (CI): 1.10-2.15], it was not associated with all-cause death at 10 years (22.1 vs. 21.6%; adjusted HR: 1.11; 95% CI: 0.83-1.47). These results were consistent when stratified by the modality of revascularization (PCI or CABG) or by anginal frequency. The sensitivity analysis replicating the analyses based on 6-month angina status resulted in similar findings. CONCLUSION: Among patients with LMCAD and/or 3VD, patient-reported RA at 1 year post-revascularization was independently associated with repeat revascularization at 5 years; however, it did not significantly increase 10-year mortality, irrespective of the primary modality of revascularization or severity of RA.

BACKGROUND: The long-term prognostic impact of a composite of periprocedural major adverse events (PMAE) following revascularisation for patients with complex coronary artery disease (CAD) has not yet been established. AIMS: This study aimed to assess the impact on 10-year mortality of non-fatal PMAE following percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Other objectives were to evaluate 1) whether PMAE affect mortality predicted by the SYNTAX score II 2020 (SSII-2020) and 2) whether optimal medical therapy (OMT) positively affects the prognosis of patients with non-fatal PMAE. METHODS: The association between 10-year mortality and non-fatal PMAE occurring within 30 days of PCI or CABG in patients with three-vessel disease and/or left main disease enrolled in the SYNTAXES study was investigated. RESULTS: The main findings are that non-fatal PMAE occurred less frequently following PCI than CABG (11.2% vs 28.2%; p<0.001) and that non-fatal PMAE were an independent predictor of all-cause mortality in the first year post-procedure, but not at 5 or 10 years, in both treatment modalities. PMAE substantially alter the individual predictions of 10-year mortality by the SSII-2020. In patients with non-fatal PMAE, OMT may provide survival benefits during the first year post-procedure as well as in the long term. CONCLUSIONS: In patients with complex CAD, non-fatal PMAE were more common following CABG than PCI, but their prognostic impact was similar, being significant in the first year and then diminishing out to 10 years. Patients with non-fatal PMAE may therefore require more careful follow-up and additional preventive treatment in the first year post-procedure.
