title: Emergency transfemoral aortic valve-in-valve implantation with the balloon-expandable Edwards-Sapien valve.
abstract: The degeneration of a previously surgically implanted aortic bioprosthesis is an increasing etiology of aortic stenosis in the elderly, but reoperative surgery may present prohibitive risks. The feasibility of transcatheter aortic valve implantation into a conventional bioprosthesis (valve-in-valve concept) has been evaluated to decrease the reoperative risk for patients with a failed bioprosthesis. There have been several reports of valve-in-valve procedures using the self-expandable prosthesis CoreValve (Medtronic Inc.), whereas the feasibility of this procedure with the Sapien balloon expandable valve (Edwards Lifesciences Inc.) is still not well established. Here we report the case of a patient submitted to balloon-expandable aortic valve-in-valve implantation in an emergency setting to treat a severe aortic stenosis due to the premature failure of a surgical bioprosthesis.
