title: Aortic valve replacement: procedure of choice in elderly patients with aortic stenosis.
abstract: Aortic valve replacement is the treatment of choice for elderly patients with aortic stenosis. It can be accomplished with excellent immediate and long-term results with significant functional improvement. Unfortunately, the literature is replete with enthusiastic reports of aortic catheter balloon valvotomy. Initial findings were controversial and the long-term results have been poor due to early valve restenosis. A retrospective analysis of our surgical experience with aortic valve replacement in the elderly seems appropriate in an effort to put this issue in proper perspective. From January 1973 to June 1993, 200 consecutive patients 70 years of age and older with severe aortic stenosis underwent surgical correction. There were 105 men (52.5%) and 95 women (47.5%), with a mean age of 76.2 years (range 70 to 89). Preoperatively, 195 patients (97.5%) were in New York Heart Association (NYHA) Class III or IV. Over one half (61.0%) of the patients experienced no hospital complications. The hospital mortality was 9.0% (18 patients). This included 14 patients in NYHA Class IV. The mean follow-up was 69.3 months and ranged from 1 to 215 months. The actuarial survival for 182 patients discharged from the hospital was 70.8% +/- 4.0% (SEM) at 72 months (73 patients at risk) and 35.2% +/- 5.4% at 144 months (20 patients at risk). Considering the advanced age and preoperative functional classification in this patient group, the results of aortic valve replacement have been excellent. The survival of patients discharged from the hospital compares favorably with a normal population matched for age and sex. The results of aortic balloon valvotomy have been disappointing.(ABSTRACT TRUNCATED AT 250 WORDS)
