Impact of residual moderate mitral regurgitation after transcatheter edge-to-edge repair on long-term survival: insights from a multicenter cohort study

Residual MR of II° occurred in 12% of patients and was more common in younger, comorbid individuals with complex MR anatomy. While survival was unaffected in the overall cohort, age <65 years emerged as a key predictor of suboptimal MR reduction. These findings highlight the need for critical patient selection and may inform individualized treatment strategies in contemporary mTEER practice.
