The impact of recurrent mitral regurgitation after surgical or transcatheter mitral valve repair: a comprehensive review and a meta-analysis.

ABSTRACT:

Background

Recurrent mitral regurgitation (MR) is typically defined as MR that is moderate or severe on follow-up echocardiography after the intervention. This meta-analysis summarizes the results of all available studies on the impact of recurrent MR on clinical outcomes after the intervention.

Methods

Medline, EMBASE, PubMed and Web of Science were searched from January 2000 to August 2024 for original studies reporting outcomes about the clinical impact of recurrent MR. Five clinical outcomes were analysed: reoperation, cardiovascular deaths, readmission, heart failure and New York Heart Association (NYHA) functional classification. The summary odds ratio (OR) with the 95% confidence interval (CI) was used to assess the risk of clinical outcomes.
