Mitral valve repair with papillary muscle re-implantation can be a successful surgical strategy for acute post-infarction mitral regurgitation due to papillary muscle rupture.
Supports papillary muscle re-implantation for post-infarction mitral regurgitation; hypothesis-generating and requires larger studies before practice change.
A 53-year-old man presenting with dyspnea and chest pain was diagnosed with acute myocardial infarction secondary to occlusion of the left circumflex coronary artery. Urgent revascularization by percutaneous stenting was successfully performed. However, the post-echocardiography revealed a ruptured papillary muscle that was causing severe mitral regurgitation and aggravation of congestive heart failure. The patient subsequently underwent mitral valve repair with papillary muscle re-implantation. Postoperative echocardiography showed a competent mitral valve without residual stenosis or regurgitation. The patient was discharged from the hospital with an uneventful recovery and has been doing well on outpatient follow up.
