Abstract
It is very important to elucidate the specific mechanism for the formation, growth, and breakdown of coronary plaque, in order to diagnose and to prevent ischemic heart disease, such as the myocardial infarction. In this study, a computational fluid dynamics using a simplified model of the right coronary artery, which deforms with contraction of the heart. The right coronary artery was modeled using an ordinary helix, whose torsion and curvature change in time with the contraction and dilatation of the heart. In the computational result, the flow in the model right coronary artery was thought to be more affected by the change of the curvature compared to that of the torsion.
