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.
