Myocardial infarction and brain infarction are caused by a vessel lesion like arteriosclerosis. It is known that vessel lesion occurs commonly at curve or bifurcation area of aortic arch and coronary artery. Stenosis by vessel lesion influences flow field of blood in arteries. This study investigated the interactions between blood flow and vessel wall of a coronary artery that has became stenosed by vessel lesion. We made elastic realistic models with stenosed at bifurcation proximity and conduct in vitro experiment. As a result, pressure drop of 0.4 kPa occurred at a stenosis in 50% stenosed model, pressure drop of 3 kPa occurred in 70% stenosed model. Moreover, in 70% stenosed model, ellipse cross-sectional collapse occurred at downstream position of a stenosis.
