Relative Survival Following TEER for Significant Mitral Regurgitation: A Contemporary Cohort Analysis.

ABSTRACT: Background/Objectives: Mitral regurgitation (MR) is the most common valvular defect worldwide, with an increasing incidence attributed to the aging population. Transcatheter edge-to-edge repair (TEER) is a viable treatment, but its long-term survival impact, particularly across sexes, remains underexplored. We aimed to assess relative survival (RS) and excess mortality (EM) in patients undergoing TEER for significant MR, with a focus on sex-based differences. Methods: We analyzed 253 patients treated with TEER between October 2015 and August 2024, stratified by sex. Observed survival (OS) was calculated using the actuarial life table method; expected survival (ES) was estimated via the Ederer II method using matched population data. Primary endpoints were RS and EM; secondary
