Acute aortic insufficiency complicating stent treatment of supravalvular aortic stenosis: successful release of trapped leaflets by wiring the stent.

Abstract

This report shows the findings observed in a 7-year-old boy patient having severe supravalvular aortic stenosis who was treated by stent implantation. Immediately after deployment, a severe acute aortic insufficiency developed due to leaflets trapped by the stent. Release was attempted percutaneously. After wiring the proximal stent, snaring the wire and pulling smoothly, the leaflets came free and valve competence was completely restored. The procedure was then successfully completed, with no residual gradient or aortic insufficiency.
