Abstract :
This research aims to understand better the effects of dynamic geometry on flow patterns in the coronary arteries, with particular attention to the flow patterns previously associated with atherogenesis in other arteries. A computational fluid dynamics model was constructed with a geometry intended to be representative of an average coronary artery bifurcation. The results indicated that the dynamic geometry has important effects on the wall shear rate, particularly along the myocardial surface (inner wall of curvature) and the outer walls of the bifurcation
