Balloon dilatation of supravalvular aortic stenosis: a report of two cases.
Balloon dilatation was performed in two cases of supravalvular aortic stenosis with variable results. There was remarkable reduction in gradient in the patient with membranous obstruction and the benefits are sustained at 18 months follow-up. The patient with hour-glass obstruction had only a partial success with reappearance of obstruction within 1 week. Balloon dilatation may emerge as a viable treatment modality for membranous obstructions. However, a large study is needed to establish the place of this procedure.
