Key result
Mitral transcatheter edge-to-edge repair (M-TEER) is safe and effective for post-myocardial infarction papillary muscle rupture, showing low in-hospital mortality and mitral regurgitation reduction.
Why the study?
Surgery for post-AMI papillary muscle rupture carries high perioperative risk, and data on M-TEER in this setting have been limited to a few case reports.
Does mitral transcatheter edge-to-edge repair improve outcomes in patients with post-myocardial infarction papillary muscle rupture and acute heart failure?

Answers are grounded in this paper and cite their sources.
M-TEER appears to be a safe and effective alternative to surgery for high-risk patients with post-AMI papillary muscle rupture, offering low in-hospital mortality and significant MR reduction.
Papillary 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.

Calì et al. (2023) conducted a systematic review in Post-myocardial infarction papillary muscle rupture and acute heart failure. Mitral transcatheter edge-to-edge repair (M-TEER) was evaluated on In-hospital mortality, complications, and mitral regurgitation reduction. Mitral transcatheter edge-to-edge repair (M-TEER) is safe and effective for post-myocardial infarction papillary muscle rupture, showing low in-hospital mortality and mitral regurgitation reduction.
