Hemodynamic Performance in Stentless Heart Valves

Not Applicable

Completed

• Conditions: Heart Valve Diseases

• Registration Number: NCT00377871
• Lead Sponsor: University of Aarhus

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.
