Abstract:
Reoperative heart valve replacement for degenerated xenografts is associated with an increased surgical risk. We used our experience with transcatheter transapical aortic valve implantation to perform a transapical off-pump aortic valve-in-a-valve implantation. Hemodynamic function was excellent and the patient had a fast and uneventful recovery.
