An aortic stenosis is a disease that an aortic valve can not open completely at a cardiac contraction phase. An aortic regurgitation is a disease that the aortic valve closes inadequately. In the aortic stenosis, flow passing through the aortic valve becomes a jet like one. In the aortic regurgitation, a reverse flow appears. It is thought that the blood flow into coronary arteries is influenced by the aortic stenosis and/or the aortic regurgitation, since the inlet of coronary arteries exist in the aortic base. Then, in this study, in order to investigate the above-mentioned influence, the modeled aortic valve was manufactured and its characteristic function was investigated. For manufacture of a model valve, the casting method using the 3-dimensional modeling machine was adopted.
