Aims: To evaluate the association between transcatheter edge-to-edge repair (TEER) and outcomes in patients with significant mitral regurgitation (MR) following acute myocardial infarction (MI), focusing on the aetiology of acute post-MI MR in high-risk surgical patients.

Methods And Results: The International Registry of MitraClip in Acute Mitral Regurgitation following Acute Myocardial Infarction (IREMMI) includes 187 patients with severe MR post-MI managed with TEER. Of these, 176 were included in the analysis, 23 (13%) patients had acute papillary muscle rupture (PMR) and 153 (87%) acute secondary MR.

Transcatheter edge-to-edge repair (TEER) is an effective intervention for high-risk patients with severe symptomatic mitral regurgitation (MR), but its acute impact on left ventricular (LV) function has not been well studied using advanced echocardiographic techniques. This study investigated the immediate effects of TEER on LV volumes and functions, as well as their influence on mid-term outcomes, using high-resolution 3D transesophageal echocardiography. In 80 patients undergoing TEER for severe MR (mean age 79±8 years, 49% with primary MR), LV end-diastolic volume (LVEDV) and stroke volume significantly decreased (161±61 to 147±54 ml and 69±18 to 50±15 ml, respectively), while end-systolic volume increased (92±60 to 97±45 ml; p<0.
