[Supravalvular ring type aortic stenosis with hypoplasia of the ascending aorta and stenosis of the origin of the innominate artery. Surgical correction].

The authors report the case of a 19 year old woman with supravalvar aortic stenosis and hypoplasia of the ascending aorta with stenosis at the origin of the innominate artery. This was a sporadic form, without mental deficiency nor facial dysmorphia. No similar case was found in the family. The patient had three attacks of bacterial endocarditis over a period of 3 years and became cured without any cardiac sequelae. In view of the onset of left ventricular failure and sequelae. In view of the onset of left ventricular failure and syncope, operation was decided. A lozange-shaped patch was placed on the aorta from the narrowed supravalvar part to the origin of the innominate artery and prolonged on the latter vessel after relief of the stenosis. This gave an excellent result.
