title: Severe supravalvular aortic stenosis: successful surgical correction by extended aortoplasty.
abstract: Surgical treatment of severe discrete supravalvular aortic stenosis by placement of a patch graft across the narrowed area of aorta at one point has been associated with a substantial incidence of residual stenosis. Successful relief of a severe stenosis was achieved by a modification of a previously reported technique in which the stenotic area is expanded at two points. Use of this technique should be considered in cases of severe discrete supravalvular aortic stenosis.
