Sex-Specific Determinants of Outcomes After Transcatheter Aortic Valve Replacement

Background Women account for a large proportion of patients treated with transcatheter aortic valve replacement, yet there remain conflicting reports about the effect of sex on outcomes. Moreover, the sex-specific prevalence and prognostic impact of frailty has not been systematically studied in the context of transcatheter aortic valve replacement. Methods and Results A preplanned analysis of the FRAILTY-AVR study (Frailty Aortic Valve Replacement) was performed to analyze the determinants of outcomes in older women and men undergoing transcatheter aortic valve replacement. FRAILTY-AVR was a multinational, prospective, observational cohort assembled at 14 institutions in North America and Europe from 2012 to 2017. Multivariable logistic regression models were stratified by sex and adjusted for covariates. Interaction between sex and each of these covariates was assessed. The primary outcome was 12-month mortality, and the secondary outcome was 1-month composite mortality or major morbidity. The cohort co...
