title: Dysfunction of a 21-mm aortic bioprosthesis treated with percutaneous implantation of a CoreValve prosthesis.
abstract: Percutaneous aortic valve replacement is an emerging alternative for high surgical risk patients with native aortic valve stenosis. We describe for the first time a valve-in-valve procedure with a CoreValve prosthesis for the treatment of a severely stenotic degenerated aortic bioprosthesis.
