N2 - The evaluation of the in vitro performances of 5 bioprosthesis designed for supra-annular implantation showed improved performances of the Mitroflow valve compared to the CE Perimount Magna. The concept of supra-annular design is exclusively related to the placement of a specifically designed prosthesis, whether mechanical or biological. The concept of supra-annular design was found to be different for the different prosthesis that were used. The new generation CE Perimount characterized by a new sewing cuff, allows the implantation of bigger size prosthesis as compared with the standard CE Perimount valve. The improved annulus-prosthesis interaction is capable of explaining the improved in vivo performance of the CE Perimount Magna. It was found that the in vivo hydrodynamic behavior of a valve might differ from the idealized assumption.
