[Congenital supravalvular aortic stenosis; report of a case].
We experienced a successful surgical case of extended aortoplasty by means of Doty's method (two sinus reconstruction) for congenital supravalvular aortic stenosis (SAS). Case was 12-year-old boy, who had no complaint except heart murmur. The retrograde aortography demonstrated localized stenosis just above the aortic valve, and it was an hour-glass type. The preoperative peak systolic pressure gradient between the left ventricle and ascending aorta was 56 mmHg, which was improved postoperatively. This case showed excellent results. Doty's aortoplasty was favorable method for SAS without deformity of aortic valve and coronary obstruction.
