Baseline characteristics and 2-year outcomes of TAVR versus SAVR were compared among males and females.Abstract: RESULTS: Baseline characteristics differed between the sexes. Despite higher Society of Thoracic Surgeons mortality risk scores (11.9 vs. 11.6; p = 0.05), female patients had lower prevalence of coronary artery disease (64.4% vs. 83.7%), prior coronary artery bypass graft surgery (19.8% vs. 61.2%), peripheral vascular disease (36.4% vs. 46.9%), diabetes mellitus (35.6% vs. 45.6%), and elevated creatinine (11.7% vs. 23.9%). Among female patients, procedural mortality trended lower with TAVR versus SAVR (6.8% vs. 13.1%; p = 0.07) and was maintained throughout follow-up (hazard ratio [HR]: 0.67; 95% confidence interval [CI]: 0.44 to 1.00; p = 0.049), driven by the transfemoral arm (HR: 0.55; 95% CI: 0.32 to 0.93; p = 0.02). Among male patients, although procedural mortality was lower with TAVR (6% vs. 12.1%; p = 0.03), there was no overall survival benefit (HR: 1.15; 95% CI: 0.82 to 1.61; p = 0.42).Abstract: CONCLUSIONS: In this retrospective subanalysis of high-risk, symptomatic aortic stenosis patients in the PARTNER trial, female subjects had lower late mortality with TAVR versus SAVR. This was especially true among patients suitable for transfemoral access and suggests that TAVR may be preferred over surgery for high-risk female patients. A randomized, controlled trial conducted specifically in female patients is necessary to properly study differences in mortality between treatment modalities.
