Stented bioprosthetic valve hemodynamics: is the supra-annular implant better than the intra-annular?

Abstract

The study results showed that, compared to intra-annular implantation, supra-annular implantation of bioprosthetic stented valves in the aortic position was associated with a significantly better hemodynamic performance of the prosthesis and significant regression of left ventricular hypertrophy.
