One of the known cures for ascending aortic aneurysm is vascular grafting surgery using composite graft. However, almost all conservative grafts don't have Valsalva sinus, and the influence of the existence of the Valsalva sinus has not been understand. In order to clarify the effect of the Valsalva sinuses existence at aortic root, some realistic models of aortic valve were manufactured in this study. The modeled aortic valves was machined by three-dimensional modeling machine, and this study has investigated the effect of the Valsalva sinus and leading angle of coronary artery on blood flow the flow field in the Valsalva sinus using particle image velocimetry (PIV) system. As the result, during systole, vortex flow occurs in the model with Valsalva sinus due to the jet from aortic leaflets.
