Abstract 11548: Gender Disparities After Transcatheter Aortic Valve Replacement With Newer Generation Transcatheter Heart Valves: A Systematic Review and Meta-Analysis

Abstract

Background: Evidence demonstrated gender disparities after transcatheter aortic valve replacement (TAVR) with early generation transcatheter heart valves (THV)s. However, it is unclear whether gender-related differences persist with the newer generation THVs. We conducted this meta-analysis and systematic review to assess gender disparities after TAVR with newer generation THVs Methods: We searched MEDLINE, and Embase databases from inception to May 2022 to identify studies that reported gender-specific outcomes after TAVR with newer generation THVs (Sapien 3, Corevalve Evolut R, and Evolut Pro). Outcomes of interests included 30-day mortality, 1-year mortality and vascular complications. Data were pooled using random-effects models to calculate pooled odds ratio (OR) and 95% conference interval (CI). Results: Four studies with a total of 47,933 patients (21,073 in females and 26,860 in males) were included. Ninety-six percent received TAVR via transfemoral approach. Females had higher 30-day mortality (OR = 1.53, 95%CI 1.31-1.79, p-value (p) < 0.001) and vascular complications (OR=1.43, 95%CI 1.23-1.65, p< 0.001). However, 1-year mortality was similar between 2 groups (OR=0.83, 95%CI 0.67-1.04, p=0.33). Conclusions: Higher 30-day mortality after TAVR in females may be attributed from higher vascular complications. Further research is needed to explore potential causes of increased mortality. While vascular complications may be an etiology, other patient characteristics or procedure-related issues should be evaluated.
