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.
