  • Title: [Emergency CABG and mitral valve replacement for anterolateral papillary muscle rupture after acute myocardial infarction].
    Author: Goh K, Kubo Y, Sasajima T, Inaba M, Yamamoto H, Otani N.
    Journal: Nihon Kyobu Geka Gakkai Zasshi; 1995 Jul; 43(7):1034-8. PubMed ID: 7561315.
    Abstract:
    A 74-year-old man developed sudden cardiogenic shock 5 days after the onset of acute myocardial infarction. Echocardiographic diagnosis was severe mitral regurgitation due to papillary muscle rupture. Despite the effort to support the hemodynamics with catecholamines and IABP, the patient's condition deteriorated rapidly, which necessitated emergency operation. Anterolateral papillary muscle was found to be totally ruptured. Coronary artery revascularization and mitral valve replacement were performed. Postoperative course was uneventful, with two days of IABP and three days of ventilatory support. The patient could start rehabilitation program on the 7th postoperative day. He was discharged in 2 months in NYHA class I. Reports of successful emergency operation for total papillary muscle rupture following acute myocardial infarction are rare. Involvement of anterolateral papillary muscle is rarer. Early diagnosis and surgical treatment are mandatory to save this group of patients.
