Balloon dilatation of supravalvular aortic stenosis: a report of two cases

Successful Percutaneous Balloon Dilatation of Supravalvular Aortic Membrane

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.

Stenting of the ascending aorta revisited

Despite few institutions stenting the ascending aorta, it has been discouraged because of the proximity of the aortic valve, the coronary artery orifices, and the aortic arch branches. We describe a small case series of patients having acquired stenosis of the ascending that was relieved successfully by stenting. © 2017 Wiley Periodicals, Inc.
