The purpose of the present study was to determine whether in vivo bifurcation geometric factors would permit prediction of the risk of atherosclerosis. It is worldwide accepted that low or oscillatory wall shear stress (WSS) is a robust hemodynamic factor in the development of atherosclerotic plaque and has a strong correlation with the local site of plaque deposition. However, it still remains unclear...
The aim of this study is to investigate the hemodynamic effect of the angulations in the left coronary bifurcation on subsequent development of coronary artery disease. Eight 3D left coronary artery models were generated based on the anatomical details and simulated for numerical analysis. The angulations at the left coronary bifurcation were simulated with angles ranging from 120°, 105°, 90°, 75°,...
Bifurcations of coronary arteries are predilection sites for atherosclerosis and expansive remodeling, the latter being associated with plaque vulnerability. Both are related to blood flow-induced shear stress (SS). We present a new approach to generate 3-D reconstructions of coronary artery bifurcations in vivo and investigate the relationship between SS, wall thickness (WT) and remodeling.The patient...
