Percutaneous valve replacement in a young adult for radiation-induced aortic stenosis

A 46-year-old woman known with relapsing Hodgkin's lymphoma diagnosed at age 5, treated with repeated cycles of radiotherapy and chemotherapy, presented with severe symptomatic radiation-induced aortic stenosis. She also had other latesequelae of radiotherapy including thyroid cancer, mediastinal fribrosis and left pulmonary fibrosis with severe restrictive lung disease and a newly diagnosed renal carcinoma. Due to the prohibitively high surgical risk and need for urgent treatment, she underwent successful transcatheter aortic valve replacement with transfemoral implantation of a 23 mm Edwards SAPIEN-XT prosthesis, which was performed without valvuloplasty of the noncalcified fibrotic valve. The finalresult was excellent with reduction of the transaortic gradient and no residual aortic regurgitation
