Major Bleeding and Mortality After Revascularization of Left Main Disease.

Background: The incidence and prognostic impact of major bleeding (MB) after percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for left main coronary artery disease (LMCAD) are unknown.

Objectives: The goal of this study was to investigate the rates and outcomes of MB after LMCAD revascularization.

Methods: In the EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with unprotected LMCAD were randomized to undergo PCI (n = 948) or CABG (n = 957) and followed up for 5 years.

Abbreviated or Standard Antiplatelet Therapy After PCI in Diabetic Patients at High Bleeding Risk.

Background: Abbreviated antiplatelet therapy (APT) reduces bleeding without increasing ischemic events in largely unselected high bleeding risk (HBR) patients undergoing percutaneous coronary intervention (PCI). Diabetes mellitus (DM) is associated with higher ischemic risk, and its impact on the safety and effectiveness of abbreviated APT in HBR PCI patients remains unknown.

Objectives: This study sought to investigate the comparative effectiveness of abbreviated (1 month) vs standard (≥3 months) APT in HBR patients with and without DM after biodegradable polymer sirolimus-eluting coronary stent implantation.

Impact of Baseline Left Ventricular Ejection Fraction on Midterm Outcomes in Women Undergoing Transcatheter Aortic Valve Implantation: Insight from the WIN-TAVI Registry.

Limited evidence exists concerning the prognostic impact of baseline left ventricular ejection fraction (LVEF) on outcomes among women undergoing transcatheter aortic valve implantation (TAVI), which we aimed to investigate in the present analysis. Patients from the Women's International Transcatheter Aortic Valve Implantation (WIN-TAVI) registry were categorized according to baseline LVEF into 3 groups: reduced (LVEF ≤40%), mildly reduced (LVEF between 41% and 49%), and preserved (LVEF ≥50%) LVEF. The primary (Valve Academic Research Consortium 2 [VARC-2]) efficacy point was defined as a composite of mortality, stroke, myocardial infarction, hospitalization for valve-related symptoms or heart failure, or valve-related dysfunction at 1 year.

Validation of the Valve Academic Research Consortium High Bleeding Risk Definition in Patients Undergoing TAVR.

The Valve Academic Research Consortium for High Bleeding Risk (VARC-HBR) has recently introduced a consensus document that outlines risk factors to identify high bleeding risk (HBR) in patients undergoing transcatheter aortic valve replacement (TAVR). The objective of the present study was to evaluate the prevalence and predictive value of the VARC-HBR definition in a contemporary, large-scale TAVR population. Multicenter study including 10,449 patients undergoing TAVR.
