Effect of branch positioning and stenosis location on flow distribution in coronary artery bifurcation

Coronary artery disease (CAD)develops when the major blood vessels that supply blood to the heart muscles become damaged or diseased. CAD occurs when the coronary arteries become narrowed or blocked because of the build- up of fat, cholesterol, and other substances within the artery wall. Using computational methods can help visualize blood flow in the coronary artery bifurcation and with the study of certain hemodynamic parameters, the occurrence of Atherosclerosis can be predicted to a certain extent. The paper mainly focuses on using two-way Fluid Structure Interaction (FSI) to simulate and study the relation between stenosis location and percentage of blockage with parameters such as Wall Shear Stress (WSS) and velocity. It was observed that Wall Shear stress increases almost linearly with increase in velocity and it was also seen that proximity of stenosis at bifurcation resulted in higher oscillatory nature of WSS
