Objectives: To assess the outcomes of transcatheter mitral
valve repair (TMVr) for failed previous surgical mitral valve repair (MVr).
Methods: We searched Pubmed, Embase, and Cochrane Library
databases for studies that reported the outcomes of TMVr for failed initial
surgical MVr. Data were extracted by 2 independent investigators and subjected to
meta-analysis. The 95% confidence interval (CI) was calculated for preoperative
demographics, peri-operative outcomes, and follow-up outcomes using binary and
continuous data from single-arm studies. Results: Eight single-arm
studies were included, with a total of 212 patients, and mean follow-up ranged
from 1.0 to 15.9 months. The pooled rate of residual procedural mitral
regurgitation
