title: Aortic valve repair using bovine pericardium for cusp extension.
abstract: Aortic valve repair with the use of individually tailored bovine pericardial extensions to the native cusps was performed in 20 patients (mean age 22 years) with severe rheumatic aortic valve incompetence. After aortic valve repair, the diastolic pressures increased significantly from a mean (+/- standard deviation) of 49 +/- 14 to 73 +/- 8 mm Hg (p less than 0.001), and cardiac catheterization showed a marked reduction or total correction of the angiographic degree of aortic regurgitation. All the patients were free of symptoms over a mean follow-up period of 7.5 months (1 to 23 months); the first 11 patients have had a mean follow-up period of 12 months. Attention is called to this short period of follow-up. Aortic valve repair with the use of bovine pericardium for cusp extension may prove to be an effective method of treatment for rheumatic aortic valve incompetence.
