Zusammenfassung:•Outcomes of overweight and obese patients were compared with normal weight patients.•Overweight BMI was independently associated with reduced mortality post-TAVI.•Obese patients were found to be more frail than normal weight patients. Transcatheter aortic valve implantation (TAVI) is emerging as the default strategy for older patients with severe, symptomatic, and trileaflet aortic stenosis. Increased body-mass index (BMI) is associated with a protective effect in patients undergoing percutaneous coronary intervention. We assessed whether elevated BMI was associated with a similar association in TAVI. We evaluated prospectively collected data from 634 patients who underwent TAVI at 2 centers from August 2008 to April 2019. Patients were stratified as normal weight (BMI 18.5 to 24.9 kg/m2, n = 214), overweight (25 to 29.9 kg/m2, n = 234), and obese (>30 kg/m2, n = 185). Outcomes were reported according to VARC-2 criteria. Mortality was assessed using Cox proportional hazards regression analysis (median follow-up 2 years). Kaplan-Meier analysis was used to estimate cumulative mortality. Baseline differences were seen in age (85 vs 84 vs 82, p
