Key result
Female sex is linked to similar 3-year survival with good health status post-TAVR versus men.
Why the study?
Sex-specific disparities in patient-reported outcomes among patients undergoing TAVR have not been fully investigated.
Does female sex improve the integrated patient-centered outcome compared to male sex in patients with symptomatic severe aortic stenosis undergoing transfemoral TAVR?
RCT (n=692)
randomized
Yes
Does female sex improve the integrated patient-centered outcome compared to male sex in patients with symptomatic severe aortic stenosis undergoing transfemoral TAVR?
Absolute Event Rate: 42.7% vs 46.1%
Despite females having lower baseline health status and males having higher mortality, there is no significant difference between sexes in achieving a patient-centered outcome of being alive with good health status at 3 years post-TAVR.
Supports comparable long-term TAVR expectations for women and men; extends prior shorter-term data to 3 years.
BACKGROUND: Sex-specific disparities in patient-reported outcomes among patients undergoing transcatheter aortic valve replacement (TAVR) are not fully investigated. OBJECTIVES: The objective of the study was to evaluate sex-based differences in clinical outcomes and health status following transfemoral TAVR in patients with symptomatic severe aortic stenosis. METHODS: Patients in the investigator-initiated, multicenter SCOPE I randomized trial were stratified by sex. Outcomes of interest included vital status and patient-reported disease-specific health status, with an integrated patient-centered outcome defined as being alive with good health status (Kansas City Cardiomyopathy Questionnaire overall summary score [KCCQ-OS] ≥75 without a decline of >10 points from baseline). RESULTS: Of the 732 patients who underwent TAVR, 692 (394 females and 298 males) were included. At baseline, female patients had a higher surgical risk and higher prevalence of advanced heart failure symptoms and frailty, whereas male patients had a greater comorbidity burden. Female patients had lower baseline KCCQ-OS, which persisted after TAVR, leading to a lower likelihood of achieving KCCQ-OS ≥75 at 1 year (64.4% vs 74.2%). In contrast, male patients had higher all-cause mortality throughout 3 years of follow-up (26.3% vs 19.5%). These contrasting patterns in patient-reported health status and survival resulted in no statistically significant difference in the proportion of patients who achieved the patient-centered outcome at 3 years (42.7% vs 46.1%). CONCLUSIONS: In this post hoc analysis of SCOPE I, there was no statistically significant difference in the likelihood of achieving the patient-centered outcome between male and female patients up to 3 years after TAVR, despite contrasting patterns in patient-reported health status and survival.

Tomii et al. (2026) conducted an RCT in symptomatic severe aortic stenosis (n=692). Female sex vs. Male sex was evaluated on Alive with good health status (KCCQ-OS ≥75 without a decline of >10 points from baseline) at 3 years. Female sex was associated with a similar likelihood of achieving the patient-centered outcome of being alive with good health status at 3 years after TAVR compared to male sex (42.7% vs 46.1%).
