[Aortic valve replacement following percutaneous transluminal balloon valvuloplasty--a case report].

A 71-year-old female was operated on, because of massive aortic regurgitation following elective percutaneous transluminal balloon aortic valvuloplasty (PTAV) for calcified bicuspid aortic stenosis. The damaged aortic valve was successfully replaced with a 19 mm St. Jude Medical prosthetic valve. More careful consideration may be required in selection of the candidates of PTAV, as the procedure is not so satisfactory as reported in literatures concerning its efficacy and safety.
