Multicenter StudyTranscatheter aortic valve-in-valve implantation for failed surgical bioprostheses: results from Polish Transcatheter Aortic Valve-in-Valve Implantation (ViV-TAVI) Registry.
Transcatheter aortic valve‑in ‑valve implantation (ViV‑TAVI) has emerged as an alternative to redo surgery in patients with failed surgical aortic bioprosthesis. ⋯ Transcatheter treatment of failed bioprostheses is increasingly common, with the best hemodynamic effect shown for supra ‑annular valves. The introduction of second‑generation valves has improved procedural and clinical outcomes.
