Update 2001: Localized supravalvar aortic stenosis: a new technique for repair

As Originally Published in 1993: Localized Supravalvar Aortic Stenosis: A New Technique for Repair by Richard B. Chard, FRACS, and Timothy B. Cartmill, FRACS. Department of Cardiac Surgery, Royal Alexandra Hospital for Children, Sydney, New South Wales, Australia. 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.
