title: Localized supravalvar aortic stenosis: a new technique for repair.
abstract: The deformity in supravalvar aortic stenosis includes generalized thickening of the tissues of the aortic root with a fairly normal sized aortic valve ring. The thickened tissues may obstruct the origins of the left and right coronary arteries. We have repaired 2 cases with complete excision of the stenosing ring below the level of the commissures of the aortic valve into the sinuses, to the level of the left and right coronary arteries.
