Between 1968 and 1971, 252 patients with severe ventricular malfunction underwent revascularization surgery. By means of single-plane ventriculography, the ventricle was divided into six segments, three anteriorly and three inferiorly, and ejection fractions were calculated. Patients were classified into four groups according to these observations. Results were assessed in regard to relief of angina, graft patency status, surgical mortality rate, and survival as determined by actuarial life-table analysis. These results were then compared to over-all medical and surgical experience contained in the Milwaukee Cardiovascular Data Registry as well as to other reported series of medical treatment for similar degrees of coronary artery disease and impairment of left ventricular function. Comparison between the surgical and medical series suggests improved survival and improved quality of life in the surgically treated patients. Thus many patients with severe ventricular malfunction, especially if associated with angina, can be reasonably considered candidates for surgery. |
