One hundred and fifty-two patients age 70 years or more underwent aortic valve replacement (AVR) at Emory University Hospital between July 1, 1974 and July 1, 1982. Of these, 98 had isolated AVR (elderly AVR group) and 54 had concomitant coronary artery bypass grafts (elderly AVR/CABG group). Results of surgery in these patients were compared to results in patients aged 20 to 69 years operated on in the same period (young AVR/CABG groups). Comparative descriptors with statistically significant differences included a higher incidence of both stable and unstable angina in patients undergoing concomitant CABGs ; less cardiomegaly in the young AVR/CABG group; less hypertension, a higher incidence of pure aortic regurgitation, and less frequent use of inotropes in the young AVR group; a higher perioperative stroke rate in elderly AVR/CABG patients; a higher perioperative psychosis rate in patients having CABGs regardless of age; and a longer postoperative hospital stay for the elderly patients. There were no significant differences between the four groups for the following descriptors: sex ratio; history of congestive heart failure; the presence of atrial fibrillation; left ventricular end diastolic pressure, ejection fraction and contractility; number of diseased coronary arteries; number of vessels bypassed; use of the intra-aortic balloon pump; re-exploration for hemorrhage; perioperative myocardial infarction rate; and major wound infection rate. Operative mortality was 5.1% for the elderly AVR group, 5.6% for the elderly AVR/CABG group, 1.9% for the young AVR group, and 5.1% for the young AVR/CABG group (p = NS). Overall, hospital mortality was 3.3%. Actuarial survival curves for all elderly versus all young patients showed no significant difference. The curve for elderly patients compares favorably with the actuarial survival of the same age group in the general population. Actuarial survival curves for the four subgroups did not differ significantly when compared at a follow-up of 36 months after surgery. We conclude that AVR with or without concomitant CABGs can be performed in elderly patients with an acceptably low mortality and morbidity, and the postoperative survival compared favorably both with younger patients and with the general population of the same age.
