Implication

Numerical simulation reasonably matches animal valve hemodynamics; extends computational validation but leaves clinical translation open.

Structured PICO

Population

Three-dimensional, realistic model of an aortic mechanical heart valve (similar to Carbomedics 27 mm) and Valsalva sinuses

Intervention

Numerical time-dependent simulation of the flow field during a fraction of the systolic period

Comparator

Experimental results at peak systole

Outcome

Flow field parameters downstream of the prosthetic device, especially in Valsalva sinusessurrogate

A 3D numerical simulation provides reasonable predictions of fluid dynamics downstream of an aortic mechanical heart valve, highlighting the role of Valsalva sinuses in valve performance.
