Mitral insufficiency secondary to coronary heart disease.
Twenty-four patients were operated on for mitral regurgitation secondary to coronary heart disease. Their common features consisted of a history of myocardial infarction, congestive heart failure, coronary occlusive disease, left ventricular dysfunction, low cardiac output, pulmonary hypertension, and increased left ventricular end-diastolic pressure. Fourteen patients were in intractable congestive heart failure at the time of operation. The operative procedures employed consisted of aneurysmectomy in 4 patients; mitral valve replacement (MVR) in 7;MVR and revascularization in 4; MVR and aneurysmectomy in 5;MVR, revascularization, and partial ventricular resection in 3; and MVR with closure of ventricular septal perforation in 1 patient. Six patients died, a hospital mortality of 25%, and only 42% had good results. The degree of associated coronary artery disease and the status of the left ventricular myocardium were the most important prognostic factors.
