Transcatheter Aortic Valve Implantation for Degenerated 19-mm Aortic Bioprosthetic Valve.

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.
