Results of surgery for congenital supravalvular aortic stenosis.
Of eight children aged 3 to 15 years with surgical correction of severe supravalvular aortic stenosis, 6 were evaluated 7 to 44 months later by repeat cardiac catheterization and aortography. Prosthetic patch angioplasty was performed in all cases. Preoperative systolic gradients ranged from 40 to 90 mm Hg (average 70); postoperative gradients ranged from 0 to 20 mm Hg (average 11). The postoperative anglographic appearance of the ascending aorta was near normal in all six patients, and none had new aortic valve insufficiency. These results of surgery for supravalvular aortic stenosis are judged to be excellent.
