Is the valve-in-valve procedure using a balloon-expanding transcatheter heart valve safe and effective for treating degenerated 19-mm aortic bioprostheses?
The valve-in-valve procedure using a balloon-expanding transcatheter heart valve is feasible, safe, and therapeutically effective for high-risk patients with a degenerated 19-mm aortic bioprosthesis.
BACKGROUND: The valve-in-valve procedure, in which a transcatheter heart valve (THV) is implanted over a prosthetic valve, has been shown to be safe and therapeutically effective, depending on the size of the replacement valve. METHODS AND RESULTS: We report 3 cases of successful valve-in-valve procedure to replace a degenerated 19-mm stented prosthetic aortic valve. Balloon-expanding THVs were implanted: 20-mm in the 1st case and 23-mm in the next 2. Aortic stenosis was almost completely resolved in all patients, who recovered promptly and without cardiac adverse events. CONCLUSIONS: Using the valve-in-valve procedure for a 19-mm degenerated bioprosthesis was feasible and safe.

Yamashita et al. (2017) conducted a cohort in Degenerated 19-mm aortic bioprosthetic valve (n=3). Transcatheter aortic valve implantation (valve-in-valve) with SAPIEN XT was evaluated on Safety and therapeutic efficacy within 30 days, based on Valve Academic Research Consortium-2. The valve-in-valve procedure using a balloon-expanding transcatheter heart valve was feasible, safe, and therapeutically effective in 3 high-risk patients with a degenerated 19-mm aortic bioprosthesis.
