The authors evaluated in vitro performances of 5 bioprosthesis designed for supra-annular implantation and showed improved performances of the Mitroflow valve compared with the CE Perimount Magna (for cardiac output 5 L/min). Inasmuch as the nominal size is not uniform for different prosthesis, they compared the size of . . . [Full Text of this Article]
