Blood Flow in Right Coronary Arteries with Multiple Stenoses

Atherosclerosis preferably occurs near the branches and bends of large and medium sized arteries. The presence of a moderate to severe stenosis significantly changes the downstream blood flow characteristics and might lead to the formation of the second stenosis. The fluid dynamic interaction of multiple stenoses is complex. The objective of this work is to study the blood flow in right coronary arteries with multiple stenoses. Various stenotic coronary models with different curvature of bend and different inter-stenotic distance are created. The computations are carried out using these models and the numerical results are compared with the blood flow simulation in a right coronary artery model reconstructed using the basic information from a coronary artery segment with two stenoses of a patient. Our results show that the curvature of bend significantly affects the wall shear stress (WSS) and pressure drop in curved artery with two moderate stenoses. The location of the distal stenosis strongly influences the flow pattern downstream, while the effect of the location of the proximal stenosis is insignificant.
