Introduction and objectives: The Valve Academic Research Consortium (VARC)-3 definition of the early safety (ES) composite endpoint after transcatheter aortic valve replacement (TAVR) lacks clinical validation. The aim of this study was to determine the incidence, predictors, and clinical impact of ES after TAVR as defined by VARC-3 criteria. Methods: We performed a multicenter study including 10 078 patients with severe aortic stenosis undergoing transarterial TAVR. According to VARC-3 criteria, ES at 30 days was defined as freedom from all-cause mortality, stroke, VARC type 2-4 bleeding, major vascular, access-related, or cardiac structural complications, acute kidney injury stages 3-4, moderate or severe aortic regurgitation, new permanent pacemaker implantation, and surgery or intervention related to the device. Baseline, procedural, and follow-up data were prospectively collected in a dedicated database. Results: ES was achieved in 6598 patients (65.5%). The main factors associated with a lack of ES were the occurrence of type 2-4 bleeding (18.9%), and new pacemaker implantation (13.6%). Advanced age, peripheral artery disease, chronic kidney disease, and balloon postdilation were associated with an increased risk of no-ES (P < .01 for all). Failure to achieve ES was associated with higher all-cause mortality up to 1-year after TAVR (HR, 3.17; 95%CI, 2.76-3.65; P < .001). Conclusions: VARC-3 ES was not achieved in up to one-third of contemporary TAVR patients, which was associated with worse mid-term outcomes. The factors associated with increased risk were advanced age, baseline comorbidities, and some procedural features (postdilation). These findings highlight the importance of continued efforts to minimize the risk of TAVR-related procedural complications. (c) 2024 Sociedad Espanola de Cardiologia.

Abstract
Introduction and objectives: The Valve Academic Research Consortium (VARC)-3 definition of the early safety (ES) composite endpoint after transcatheter aortic valve replacement (TAVR) lacks clinical validation. The aim of this study was to determine the incidence, predictors, and clinical impact of ES after TAVR as defined by VARC-3 criteria. Methods: We performed a multicenter study including 10 078 patients with severe aortic stenosis undergoing transarterial TAVR. According to VARC-3 criteria, ES at 30 days was defined as freedom from all-cause mortality, stroke, VARC type 2-4 bleeding, major vascular, access-related, or cardiac structural complications, acute kidney injury stages 3-4, moderate or severe aortic regurgitation, new permanent pacemaker implantation, and surgery or intervention related to the device. Baseline, procedural, and follow-up data were prospectively collected in a dedicated database. Results: ES was achieved in 6598 patients (65.5%). The main factors associated with a lack of ES were the occurrence of type 2-4 bleeding (18.9%), and new pacemaker implantation (13.6%). Advanced age, peripheral artery disease, chronic kidney disease, and balloon postdilation were associated with an increased risk of no-ES (P < .01 for all). Failure to achieve ES was associated with higher all-cause mortality up to 1-year after TAVR (HR, 3.17; 95%CI, 2.76-3.65; P < .001).
