Aortic valve replacement in patients 75 years old and older.

A consecutive group of 100 patients in the eighth decade of life who had aortic valve replacement (AVR) from 1975 through 1986 were retrospectively studied. Eighty-five of them were in New York Heart Association (NYHA) Functional Class III or IV. Isolated AVR was performed in 44 patients and AVR with concomitant procedures, in 56. Perioperative mortality (30 days) was 3%, and perioperative morbidity included 83 complications in 60 patients. Long-term follow-up was available on 93 patients, 71 of whom were alive and 22 of whom were dead. Sixty-eight of the 71 long-term survivors are now in NYHA Class I or II. The low rate of perioperative mortality and the improved quality of life after AVR support the performance of this procedure in this older population.
