Stenting of a stenotic aortic homograft in pulmonary position after the Ross procedure.

Pulmonary autograft replacement of the aortic valve (Ross procedure) has potential advantages, with favorable rates of survival and freedom from reoperation. The procedure itself, however, involves insertion of a homograft in the pulmonary position. The development of severe homograft stenosis is an uncommon but clinically important complication. We report the case of a young female who developed a symptomatic homograft stenosis a year after she underwent the Ross procedure. The lesion was stented successfully and the homograft's patency, together with a markedly improved pressure gradient, was still maintained eight months after percutaneous stenting.
