Why the study?

Sex-based morphological, physiological, and baseline characteristic differences may impact outcomes between sexes after TAVR.

Do outcomes after transcatheter aortic valve replacement (TAVR) differ between female and male patients?

Population

657,850 patients (351,927 males and 305,923 females) undergoing TAVR across 58 studies

Comparison

Female vs male patients

Design

Meta-analysis and meta-regression

Follow-up

Up to 1 year

Key result

Female patients undergoing TAVR had higher in-hospital mortality (RR 1.16; 95% CI 1.02-1.32; p=0.02) but lower 1-year mortality (RR 0.87; 95% CI 0.82-0.93; p<0.01) compared to males.

Overview

Females may warrant heightened periprocedural vigilance during TAVR; leaves open whether sex-specific strategies improve net outcomes.

Key Points

  • This meta-analysis aims to examine sex-related differences in outcomes following transcatheter aortic valve replacement (TAVR).
  • Analyzed data from 58 studies involving 657,850 patients undergoing TAVR.
  • Compared in-hospital and 1-year mortality rates between males and females.
  • Utilized meta-regression to identify factors influencing outcomes such as age and comorbidities.
  • Females had higher in-hospital mortality (RR 1.16) but lower 1-year mortality (RR 0.87).
  • No significant differences in 30-day mortality or cardiovascular mortality at 30 days and 1 year.
  • Females experienced higher risks for major bleeding and vascular complications, while acute kidney injury was less frequent in females.

Main Result

Effect estimate: RR 1.16 (95% CI 1.02-1.32)

p-value: p=0.02

In patients undergoing TAVR, females face higher short-term risks including in-hospital mortality, stroke, and bleeding, but have lower 1-year all-cause mortality compared to males.

Cite This Study

Benhammou et al. (2025) conducted a meta-analysis in symptomatic aortic stenosis (AS) (n=657,850). Female sex vs. Male sex was evaluated on in-hospital mortality (RR 1.16, 95% CI 1.02-1.32, p=0.02). Female patients undergoing TAVR had higher in-hospital mortality (RR 1.16; 95% CI 1.02-1.32; p=0.02) but lower 1-year mortality (RR 0.87; 95% CI 0.82-0.93; p<0.01) compared to males.
