Abstract
We study the dynamic behaviour of aortic and chorded mitral prostheses using numerical and experimental methods. An Immersed Boundary (IB) code is developed for the numerical analysis. A left heart simulation rig is used to subject the valves to physiological pressure and flow conditions in a controlled environment. Pressure gradients are recorded and compared with our numerical simulations for four different cycling flow rates. Good agreement is found for both aortic and mitral valves. We conclude that the IB is a very effective tool to study the pressure gradients across heart valve prostheses.
