• Seventy-three patients aged 60 and over and 277 patients under 60 years of age underwent isolated aortic valve replacement (AVR) for aortic stenosis, regurgitation, and mixed disease from 1966 through 1975. Cardiac catheterization was performed five to nine months following operation in 77% of these patients. Follow-up averaged 55 months per patient. The hospital mortality in the elderly group was 2.7%, compared to 5.8% in the younger group. The late cardiac mortality was 21% and 19%, respectively. There was significant improvement (P <.001) in the left ventricular end-diastolic pressure, cardiac index, and functional class in each of the three disease groups in the younger as well as the elderly patients. More important, the magnitude of improvement in each of these variables in patients over and under 60 years of age was not significantly different. Increasing longevity will make cardiac operations more common in the older population. These findings indicate that AVR carries the same low risk and brings about a similar improvement in left ventricular pump function in patients older and younger than 60.
