Sex-Specific Determinants of Outcomes After Transcatheter Aortic Valve Replacement
2019
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.
