Among 236 aortic valves surgically excised at the Mayo Clinic in 1990 (mean patient age, 66 years; age range, 10 to 92 years), 154 (65%) were stenotic, 58 (25%) were insufficient, and 24 (10%) were both stenotic and insufficient.
Pure stenois was related to calcification, and causes included degenerative (51%), bicuspid (36%), postinflammatory (9%), and other (4%) reasons.
Fourteen (9%) valves with pure stenosis also underwent ventricular septal myectomy, 12 for hypertrophy and two for co-existent hypertrophic cardiomyopathy.
