Abstract

A computer model was employed to study parametrically epicardial blood flow in the left coronary arteries. The model includes the effects of branching as well as the non-linear elastic properties of the artery walls. Branches are included on a discrete basis, where at each branch point a mass balance and two momentum balances are written. These three equations, together with an additional equation, e. g. a lumped impedance for each branch, determine the flow conditions in the region of branching. Between branch points, the artery is modeled as straight and elastic.
