NCT00377871

Brief Summary

Hypothesis: Stentless bioprostheses will perform superior to stented bioprostheses in different hemodynamic and biomechanical parameters. The study will investigate turbulence, flow and aortic root movement in a stentless bioprosthesis and compare it to a stented bioprosthesis.
