Objectives The aim of this study was to compare, in a large all-comer registry, the long-term clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for ostial/mid-shaft lesions versus distal bifurcation lesions in unprotected left main coronary artery (ULMCA) stenosis. Background Limited data are available regarding clinical outcomes following DES implantation at the different ULMCA sites. Methods Patients with ULMCA stenosis treated by PCI with DES were analyzed in this multinational registry. Results A total of 1,612 patients were included: 482 were treated for ostial/mid-shaft lesions versus 1,130 for distal bifurcation lesions. At a median follow-up period of 1,250 (interquartile range: 987 to 1,564) days, PCI for distal bifurcation lesions was associated with a higher incidence of major adverse cardiac events (propensity-score adjusted hazard ratio [HR]: 1.48, 95% confidence interval [CI]: 1.16 to 1.89; p = 0.001), largely because of the higher target vessel revascularization rate observed in this group as compared to the ostial/mid-shaft lesions group (propensity-score adjusted HR: 1.68, 95% CI: 1.19 to 2.38; p = 0.003). These results were sustained following propensity-score matched analysis. With regard to all-cause death and the composite endpoint of all-cause death and myocardial infarction, propensity-score adjusted analysis suggested a trend toward higher rates of these in the distal ULMCA PCI group, although this was not observed in the propensity-score matched analysis. Conclusions This study demonstrates that PCI for ostial/mid-shaft lesions is associated with better clinical outcomes than are distal bifurcation lesions in ULMCA, largely because there is a lower need for repeat revascularization in ostial/mid-shaft lesions.

OBJECTIVES: The aim of this study was to compare, in a large all-comers registry, major adverse cardiac and cerebrovascular events (MACCE) after percutaneous coronary intervention (PCI) with first-generation drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) in unprotected left main coronary artery (ULMCA) stenosis. BACKGROUND: Percutaneous coronary intervention with DES implantation in ULMCA has been shown to be a feasible and safe approach at midterm clinical follow-up. METHODS: All consecutive patients with ULMCA stenosis treated by PCI with DES versus CABG were analyzed in this multinational registry. A propensity score analysis was performed to adjust for baseline differences in the overall cohort. RESULTS: In total 2,775 patients were included: 1,874 were treated with PCI versus 901 with CABG. At 1,295 (interquartile range: 928 to 1,713) days, there were no differences, at the adjusted analysis, in the primary composite endpoint of death, cerebrovascular accidents, and myocardial infarction (MI) (adjusted hazard ratio [HR]: 1.11; 95% confidence interval [CI]: 0.85 to 1.42; p = 0.47), mortality (adjusted HR: 1.16; 95% CI: 0.87 to 1.55; p = 0.32), or composite endpoint of death and MI (adjusted HR: 1.25; 95% CI: 0.95 to 1.64; p = 0.11). An advantage of CABG over PCI was observed in the composite secondary endpoint of MACCE (adjusted HR: 1.64; 95% CI: 1.33 to 2.03; p < 0.0001), driven exclusively by the higher incidence of target vessel revascularization with PCI. CONCLUSIONS: In our multinational all-comers registry, no difference was observed in the occurrence of death, cerebrovascular accidents, and MI between PCI and CABG. An advantage of CABG over PCI was observed in the incidence of MACCE, driven by the higher incidence of target vessel revascularization with PCI

Objectives The aim of this study was to report the long-term clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) for ostial/midshaft lesions in an unprotected left main coronary artery (ULMCA). Background Data regarding outcomes in these patients are limited. Methods Of a total of 2,775 patients enrolled in the DELTA multinational registry, 856 patients with isolated ostial/midshaft lesions in an ULMCA treated by PCI with DES (n = 482) or CABG (n = 374) were analyzed. Results At a median follow-up period of 1,293 days, there were no significant differences in the propensity score-adjusted analyses for the composite endpoint of all-cause death, myocardial infarction (MI), and cerebrovascular accident (hazard ratio [HR]: 1.21, 95% confidence interval [CI]: 0.79 to 1.86; p = 0.372), all-cause death (HR: 1.35, 95% CI: 0.80 to 2.27; p = 0.255), the composite endpoint of all-cause death and MI (HR: 1.33, 95% CI: 0.83 to 2.12; p = 0.235) and major adverse cardiac and cerebrovascular events (HR: 1.34, 95% CI: 0.93 to 1.93; p = 0.113). These results were sustained after propensity-score matching. However, a higher incidence of target vessel revascularization (HR: 1.94, 95% CI: 1.03 to 3.64; p = 0.039) was observed in the PCI compared with the CABG group, with a trend toward higher target lesion revascularization (HR: 2.00, 95% CI: 0.90 to 4.45; p = 0.090). Conclusions This study demonstrates that PCI for ostial/midshaft lesions in an ULMCA is associated with clinical outcomes comparable to those observed with CABG at long-term follow-up, despite the use of older first-generation DES.

Percutaneous coronary intervention (PCI) with drug-eluting stents is an accepted alternative to surgery for the treatment of unprotected left main coronary artery (ULMCA) disease, but the long-term outcome in elderly patients is unclear. Aim of our study was to compare the clinical outcomes of octogenarians with ULMCA disease treated either with PCI with drug-eluting stents or coronary artery bypass grafting (CABG). The primary study end point was the composite of death, cerebrovascular accident, and myocardial infarction at follow-up. A total of 304 consecutive patients with ULMCA stenosis treated with PCI or CABG and aged 80 years were selected and analyzed in a large multinational registry. Two hundred eighteen were treated with PCI and 86 with CABG. During the hospitalization, a trend toward a higher mortality rate was reported in PCI-treated patients (3.5% vs 7.3%, p = 0.32). At a median follow-up of 1,088 days, the incidence of the primary end point was similar in the 2 groups (32.6% vs 30.2%, p = 0.69). Incidence of target vessel revascularization at follow-up was higher in PCI-treated patients (10% vs 4.2%, p = 0.05). At multivariate analysis, left ventricular ejection fraction was the only independent predictor of the primary end point (hazard ratio 0.95, 95% confidence interval 0.91 to 0.98, p = 0.001). After adjustment with propensity score, the revascularization strategy was not significantly correlated to the incidence of the primary end point (hazard ratio 0.98, 95% confidence interval 0.57 to 1.71, p = 0.95). In octogenarians, no difference was observed in the occurrence of the primary end point after PCI or CABG for the treatment of ULMCA disease. However, the rate of target vessel revascularization was higher in the PCI group. (C) 2014 Elsevier Inc. All rights reserved.

Women typically present with coronary artery disease later than men with more unfavorable clinical and anatomic characteristics. It is unknown whether differences exist in women undergoing treatment for unprotected left main coronary artery (ULMCA) disease. Our aim was to evaluate long-term clinical outcomes in women treated with percutaneous coronary intervention (PCI) with drug-eluting stents versus coronary artery bypass grafting (CABG). All consecutive women from the Drug-Eluting stent for LefT main coronary Artery disease registry with ULMCA disease were analyzed. A propensity matching was performed to adjust for baseline differences. In total, 817 women were included: 489 (59.8%) underwent treatment with PCI with drug-eluting stents versus 328 (40.2%) with CABG. Propensity score matching identified 175 matched pairs, and at long-term follow-up there were no differences in all-cause (odds ratio [OR] 0.722, 95% confidence interval [CI] 0.357 to 1.461, p = 0.365) or cardiovascular (OR 1.100, 95% CI 0.455 to 2.660, p = 0.832) mortality, myocardial infarction (MI; OR 0.362, 95% CI 0.094 to 1.388, p = 0.138), or cerebrovascular accident (CVA; OR 1.200, 95% CI 0.359 to 4.007, p = 0.767) resulting in no difference in the primary study objective of death, MI, or CVA (OR 0.711, 95% CI 0.387 to 1.308, p = 0.273). However, there was an advantage of CABG in major adverse cardiovascular and cerebrovascular events (OR 0.429, 95% CI 0.254 to 0.723, p = 0.001), driven exclusively by target vessel revascularization (OR 0.185, 95% CI 0.079 to 0.432, p

textabstractAims: Data regarding the impact on clinical outcomes of PCI with DES implantation vs. CABG to treat unprotected left main coronary artery (ULMCA) disease in diabetic patients are still insufficient. The present study evaluated the short-term and long-term results of percutaneous and surgical revascularisation in diabetic patients with ULMCA disease in a large population. Methods and results: A total of 826 diabetic patients with ULMCA stenosis who received DES (n=520) or underwent CABG (n=306) were selected and analysed from the DELTA registry. In-hospital MACCE was significantly higher in the CABG group, mainly driven by a higher incidence of MI. At four-year follow-up, freedom from death and the composite endpoint of death, MI and cerebrovascular accident (CVA) was similar in the two treatment groups (CABG 87.4%, PCI 82.5%, p=0.124, and CABG 85.4%, PCI 78.9%, p=0.11, respectively). Conversely, freedom from TVR and MACCE was significantly higher in the CABG compared to the PCI group (CABG 95.4%, PCI 79.4%, p
