Abstract
Aortic valve stenosis was evaluated in 26 patients in the eighth decade of life, representing 20% of all patients referred for aortic valve stenosis. There were no clinical features which distinguished this older group from younger patients. Coronary artery disease was present in 46% of the older group, 30% in the younger. Angina pectoris or an infarction pattern on the electrocardiogram was not useful in predicting coronary artery disease in either group. A dominant left coronary circulation was more frequent (22%) in the younger than the older group. This was related to the higher incidence of congenitally deformed aortic valves (55%) found in the younger, compared in the advanced age group (5%). The surgical mortality in the younger and advanced age group was 8 and 20%, respectively. Mortality in both groups was related in more than half the patients to coronary artery disease.
