Congenital supravalvular aortic stenosis is due to a variety of anomalies in the proximal portion of the ascending aorta. Clinically, however, the most important lesion is a circular constriction of the aortic wall above the valve cusps. In certain patients with this type of anomaly, the supravalvular aortic stenosis constitutes one element of a clinical syndrome marked also by impaired growth, mental deficiency, and a characteristic facial appearance. Three patients with the features of this syndrome have been seen in this hospital since 1955. The purpose of this report is to present these patients whose syndrome was first described by Williams et al in New Zealand.
