Abstract
A method was developed to construct parametrically defined computational fluid mechanical models in order to study the effects of time-varying coronary artery constrictions. Stenosis severity values input were 90%, 75 and 50% of the arterial cross sectional area reduction. The time course of the spasmic changes were assumed to have a trigonometrically varying nature. In the preliminary computations, significant decreases in the average flow rate was found to affect the overall flow structures. The application of the dynamically moving boundary model was demonstrated to be a useful tool in order to investigate the mechanism of an ischemic event provoked by a coronary spasm
