Surgical treatment of papillary muscle rupture

DA Killen, WA Reed, S Wathanacharoen, G Beauchamp and B Rutherford

Between 1971 and 1979, 16 patients underwent mitral valve replacement for papillary muscle rupture after infarction. Nine of these patients were operated on within 3 days of papillary muscle rupture. Eight patients had low cardiac output syndrome prior to operation. Six patients had concomitant coronary artery bypass, and 1 patient had resection of an associated left ventricular aneurysm. There were 3 operative deaths (19% mortality). Surviving patients have been followed for a total of 49 patient-years. There have been 2 late deaths, each a result of coronary artery disease. Six of the 11 surviving patients are asymptomatic; the others are in New York Heart Association Functional Class II or III. The actuarial 5-year survival was 75%. These data support the concept that an aggressive attitude should be taken toward early diagnosis and surgical treatment of postinfarction papillary muscle rupture.
