In coronary artery disease, aortic valve may have a critical effect for stenosed coronary flow. Vortex formed by the aortic valve in sinus valsalva increases coronary flow. Therefore, we have built up coronary artery model containing aortic valve. For this purpose, coronary 3D model with the aortic valve was made based on anatomical shape. Then, we developed lumped parameter model of coronary circulation. Blood is assumed incompressible and Newtonian fluid. Finite element analysis was performed for Navier-Stokes equation. Then we compared the hemodynamic charateristics of the models with and without aortic valve.
