title: [Supravalvular aortic stenosis in two black patients].
abstract: Two male black patients, 18 and 12-year-old, with mental retardation and typical elfin face, presented with severe supravalvular aortic stenosis, thus characterizing Williams's or aortic supravalvular stenosis syndrome. Both were submitted to surgical treatment of the stenosis, and are asymptomatic after a one and four years follow-up. For the first time this syndrome, in its classical form, is described in black patients.
