Women comprise ≥50% patients undergoing TAVR. Several data have shown the noninferiority of TAVR compared with surgical aortic valve replacement for symptomatic significant aortic stenosis, but no study so far has been specifically powered to detect differences by sex.
This study sought to examine the safety and performance of contemporary transcatheter aortic valve replacement (TAVR) in an exclusive all-women TAVR population, and to further investigate the potential impact of female sex-specific characteristics on composite 1-year clinical outcomes.
A total of 1,019 intermediate to high-risk women, with mean age 82.5 ± 6.3 years, mean European System for Cardiac Operative Risk Evaluation (EuroSCORE) I 17.8 ± 11.7% and mean Society of Thoracic Surgeons score 8.3 ± 7.4% were enrolled. TAVR was performed via transfemoral access in 90.6% and new-generation devices were used in 42.1%.
Intermediate to high-risk women enrolled in this first ever all-women contemporary TAVR registry experienced a 1-year VARC-2 composite efficacy endpoint of 16.5%, with a low incidence of 1-year mortality and stroke. Prior revascularization and EuroSCORE I were independent predictors of the VARC-2 efficacy endpoint, whereas EuroSCORE I, baseline atrial fibrillation, and prior percutaneous coronary intervention were independent predictors of the 1-year death or stroke.
