Successful percutaneous balloon dilatation of supravalvular aortic membrane

Abstract

Supravalvular aortic stenosis is the least common type of left ventricular outflow tract obstruction. Primary balloon dilatation of membranous supravalvular aortic stenosis was performed in a 10-year-old male child with a remarkable reduction in systolic pressure gradient. Balloon dilatation is a feasible treatment modality for membranous supravalvular aortic stenosis. It provides good immediate results and sustained relief of stenosis.
