Transcatheter edge‐to‐edge mitral valve repair for post‐myocardial infarction papillary muscle rupture and acute heart failure: A systematic review

Abstract

AbstractPapillary muscle rupture (PMR) is a rare complication of acute myocardial infarction (AMI) associated with high mortality and morbidity. Surgery is the gold‐standard treatment for these patients, but it is burdened by a high perioperative risk due to hemodynamic instability. Mitral transcatheter edge‐to‐edge repair (M‐TEER) was reported to be safe and effective in unstable patients with significant mitral regurgitation. However, data in patients with post‐AMI PMR are limited to a few case reports. In this review, we summarized all data available regarding percutaneous treatment of post‐AMI PMR. These results show that M‐TEER is safe and effective in this setting with low in‐hospital mortality and complications and high rate of significant mitral regurgitation reduction.
