Limited Expansion of the New Self-Expandable Transcathether Aortic Valve Prosthesis (CoreValve Evolut R).
Transcatheter aortic valve implantation (TAVI) has been established as a therapeutic option in patients with a high procedural risk presenting with severe aortic stenosis. Recent improvements of TAVI technology made it possible to treat degenerated bioprosthesis using the valve-in-valve implantation concept. The self-expanding CoreValve (Medtronic, Minneapolis, MN) prosthesis has recently been redesigned and was introduced into clinical practice. We report a case of a not fully expanded Medtronic CoreValve Evolut R after deploying a 26 mm prosthesis into a degenerated 25 mm Carpentier-Edwards Perimount prosthesis.
