This study determined patient-specific WSS in the proximal coronary arteries by modeling flow in the aorta and coronary arteries. A combination of magnetic resonance imaging (MRI) and computation fluid dynamics (CFD) was used to study the flow fields in 4 subjects. The study showed significant skewing of the velocity profiles in the proximal coronary arteries caused by the presence of a transient vortex at the ostia. Results presented here are consistient with the observation that athersclerotic plaques preferentially form in areas of low or oscillatory WSS.
