Hemodynamic Performance in Stentless Heart Valves

Hemodynamic Performance in Stentless Heart Valves

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.

Inclusion Criteria:

• Over 65 years old
• Submitted for aortic valve surgery
• No coronary surgery other than LIMA to LAD

Exclusion Criteria:

• Stentless valve implantation not possible
• Contraindications for MRI scan
