ABSTRACT
BACKGROUND:
The effect of sex on mortality is controversial; furthermore, sex differences in left ventricular (LV) remodeling after transcatheter aortic valve implantation (TAVI) remain unknown.MethodsâandâResults:
This study included 2,588 patients (1,793 [69.3%] female) enrolled in the Optimized CathEter vAlvular iNtervention (OCEAN)-TAVI Japanese multicenter registry between October 2013 and May 2017. We retrospectively analyzed the effect of sex on mortality, and evaluated changes in the LV mass index (LVMI) after TAVI. Female sex was significantly associated with lower all-cause and cardiovascular mortality (log-rank P<0.001 for both). Multivariate analysis showed that female sex was independently associated with lower cumulative long-term mortality (hazard ratio 0.615; 95% confidence interval 0.512-0.738; P<0.001). Regression in the LVMI was observed in both sexes, and there was no significant difference in the percentage LVMI regression from baseline to 1 year after TAVI between women and men. Women had a survival advantage compared with men among patients with LVMI regression at 1 year, but not among patients with no LVMI regression.CONCLUSIONS:
We found that female sex is associated with better survival outcomes after TAVI in a large Japanese registry. Although LVMI regression was observed in women and men after TAVI, post-procedural LV mass regression may be related to the sex differences in mortality.Palavras-chave
