Surgical management of aortic valve disease in the elderly: a longitudinal analysis

From November, 1972, through December, 1986, 219 consecutive patients 70 years of age and older with aortic stenosis (AS) underwent aortic valve replacement. One hundred seven of them had isolated pure AS, and 112 had AS and coronary artery disease (AS + CAD). The mean age of the AS group was 75.4 years (range, 70 to 88 years) and of the AS + CAD group, 74.8 years (range, 70 to 86 years). The mean aortic valve gradient in the AS group was 87.7 +/- 30.6 mm Hg and in the AS + CAD group, 68.0 +/- 51.3 mm Hg (p less than 0.001). Hospital mortality for the AS group was 12.1% (13 patients) and for the AS + CAD group, 8.9% (10 patients). The long-term survival at seven years was 77.2 +/- 5.5% (+/- the standard error of the mean) for the AS group and 57.0 +/- 6.9% for the AS + CAD group (p less than 0.006). Postoperative assessment reveals substantial functional improvement. These early and long-term favorable results provide a much needed reference point when valvuloplasty is being considered. Aortic valve replacement is the treatment of choice in elderly patients with symptomatic AS.
