Sex disparities in patients with symptomatic severe aortic stenosis

We evaluated whether there is equitable distribution across sexes of treatment and outcomes for aortic valve replacement (AVR), via surgical (SAVR) or transcatheter (TAVR) methods, in symptomatic severe aortic stenosis (ssAS) patients. Using de-identified data, we identified 43,822 patients with ssAS (2008-2016). Multivariate competing risk models were used to determine the likelihood of any AVR, while accounting for the competing risk of death. Association between sex and 1-year mortality, stratified by AVR status, was evaluated using multivariate Cox regression models with AVR as a time-dependent variable. Among patients with ssAS, 20,986 (47.9%) were female. Females were older (median age 81 vs. 78, P
