The Surgical Treatment of Supravalvular Aortic Stenosis Based on Two Cases

Abstract

An increasing number of cases of supravalvular aortic stenosis have been reported in recent years. In those hitherto described, the stricture has consisted of either a fibrous membrane directly adjacent to the cusps or a true stenosis at the level of the upper border of the sinus of Valsalva where, as mentioned by Kreel, Reiss, Strauss, Blumenthal, and Baronofsky (1959), a slight, * In Case 1, operation consisted of local excision of the stenosis; and in Case 2, of splitting the aorta through the stenosis and insertion of a patch graft.
