Key result
Transapical off-pump aortic valve-in-a-valve implantation was successfully performed in two elderly patients with a severely degenerated porcine aortic bioprosthesis.
Case Report (n=2)
Transapical off-pump aortic valve-in-a-valve implantation demonstrates procedural feasibility in high-risk elderly patients with degenerated porcine bioprostheses.
May offer option for high-risk reoperative cases; leaves open durability, safety, and generalizability pending larger prospective data.
Re-operative heart-valve replacement is a high-risk procedure and even more so in elderly patients. Another option in high-risk patients with a degenerated aortic xenograft is the implant of a second aortic bioprosthesis using a transcatheter approach. We report two cases of patients with a severely degenerated porcine aortic bioprosthesis who were successfully treated by a transapical valve-in-a-valve implantation.
