Transcatheter Mitral Valve Implantation: Supra-Annular and Subvalvular Fixation Techniques
Loger and colleagues implanted transcatheter prostheses in the mitral valve position in 33 pigs. Valve performance and heart function were analyzed for both supra-annular and subvalvular fixation. The supra-annular valve deployment was associated with a low degree of paravalvular leakage and was well-tolerated in the hearts, resulting in excellent three-month outcomes for these animals.
