[The first experience with using xenografts in treatment of aortic valve disease]

A comparative analysis of biomechanics of implanted xenografts has shown that the functioning of the newly formed aorta root might be dependent on constructive features of the bioprosthesis, choice of the optimal type size and on the implantation technique. The best hemodynamic and biomechanical characteristics were obtained when using the technique of a complete prosthesis of the aorta root with the Medtronic Freestyle xenograft and subcoronary implantation of bioprosthesis AB-Mono- and AB-Composit-Kemerovo.
