Why the study?
Surgical mitral valve repair or replacement has been the mainstay for severe post-MI MR, but operative risk is often high due to ventricular dysfunction, coronary disease burden, and comorbidities.
Cohort
No results reported in this Level 4 retrospective analysis; leaves open comparative effectiveness of surgical versus transcatheter mitral intervention after MI.
Myocardial infarction (MI) remains a major cause of morbidity and mortality in the United States, and up to half of patients with MI develop mitral regurgitation (MR).1 MR after MI reflects disruption of the left ventricle and mitral apparatus and is associated with increased risks of heart failure, rehospitalization, and mortality.2,3 Surgical mitral valve repair or replacement has traditionally been the mainstay of treatment for severe post-MI MR; however, operative risk is often high due to ventricular dysfunction, coronary disease burden, and comorbidities.

Rajendran et al. (2026) conducted a cohort in Myocardial infarction with concomitant mitral regurgitation. Surgical mitral valve repair or replacement vs. Transcatheter mitral valve repair or replacement was evaluated.
