A Surgical Case of Papillary Muscle Rupture after Acute Myocardial Infarction with Cardiogenic Shock

Abstract

Papillary muscle rupture is considered to be one of the least frequently observed complications of acute myocardial infarction (AMI) and has a significantly high mortality. We report a case of a patient who survived due to an emergency surgery for papillary muscle rupture after AMI with cardiogenic shock. A 64-year-old male patient was emergently admitted with chest pain as the chief complaint. He was diagnosed with papillary muscle rupture after AMI by electrocardiography, cardiac catheterization, and echocardiography. Since he had gone into cardiogenic shock during cardiac catheterization, he received assisted circulation with intraaortic balloon pumping and emergent mitral valve replacement. Complete rupture of the posterior papillary muscle and severe mitral regurgitation were observed intraoperatively. The postoperative condition was favorable with no complication and the patient was discharged 12 days after the operation.
