Valve-in-valve implantation of Medtronic CoreValve prosthesis in patients with failing bioprosthetic aortic valves.
Transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve (MCV) system might represent an alternative to conventional redo surgery in older high-risk patients with a failing aortic valve bioprosthesis. ⋯ These results suggest that transfemoral mcv implantation into a wide range of degenerated aortic bioprosthetic valves - irrespective of the failure mode - is feasible, safe, and improves hemodynamics in older patients with higher risk for conventional aortic valve redo surgery.
