title: Concomitant aortic valve replacement and myocardial revascularization.
abstract: Twenty-six consecutive patients underwent combined aortic valve replacement and myocardial revascularization at the Emory University Affiliated Hospitals between May, 1973 and March, 1976. Acute myocardial infarction resulted in two operative deaths (8%). There have been four late deaths, all Class IV preoperative. The age range was 37 to 79 years with an average age of 60. Preoperatively all patients were Class IV or late Class III. Twenty-three patients had symptoms of angina pectoris; congestive heart failure was evident in 56%. Postoperatively, 70% are now Class 1 or II. Single coronary bypass was performed in 16 patients, double in 6, and triple in three. Double bypass plus mitral valve replacement was required in two with aneurysmectomy in one. The rate of intraoperative infarction was 27% for the series but only 7% in the last year. The methods of intraoperative myocardial preservation and the technical approach for the operative procedures were variable. Results with each method are correlated, and currently preferred techniques are presented and discussed. Best results were obtained in patients who presented early in their symptomatic course with isolated proximal coronary lesions and good renoff vessels. Excellent results could be achieved despite advanced age of patients, requirement for multiple bypass grafts, and correction of other associated cardiac lesions. Poorest results were obtained when long-standing ventricular failure was combined with poor vessels distal to coronary stenoses.
