抄録

Local velocity profile and shear tress distribution downstream from the aortic valve and in the model of human aorta were measured by using Laser Doppler Velocitimetry. BSS and LK valves provide high velocity and high shear stress in the outer curve region of ascending aorta for OCO while downstream just from the major orifice and the inner curve region of the ascending aorta for ICO. However, less effect of the valve orientation can be observed in the descending aorta. CE valve provides a high level of turbulence intensity and shear stress in the annulaz region between the outflow surfaces of the leaflets and the flow channel wall as well as the top of aortic arch.
