[en] Between 1983 and 1988, thirteen patients (12 men and 1 women, average age 63 years) were operated in the acute phase of myocardial infarction for papillary muscle rupture (PMR). The rupture involved the posterior papillary muscle in 12 cases. The average left ventricular ejection fraction was 47 +/- 9 per cent (range 34 to 63%). Pulmonary capillary pressures ranged from 76 to 41 mmHg (average 35 mmHg). Eleven patients presented with acute pulmonary oedema and 7 had cardiogenic shock. Coronary arteriography showed triple vessel disease in 3 cases, double vessel disease in 7 cases and single vessel disease in 3 cases. Surgery was carried out on average 2.7 days after the rupture and 10 days after the initial infarct. In addition to mitral valve replacement (N = 13), 11 patients underwent a myocardial revascularisation procedure. The operative mortality was 15 per cent (N = 2). Papillary muscle rupture in the acute phase of myocardial infarction causes cardiac failure which is related more to the mechanical abnormality than to an alteration of left ventricular function. Considering the operative mortality and the natural history of PMR treated medically, the authors recommend early surgery as the only management which can improve the precarious haemodynamic status of patients with this complication.
