Abstract

Shear stress is known to play a central role in RESTENOSIS formation and is sensitive to STENT geometry. This article presents 2D and 3D computational fluid dynamics models to analyze steady blood flow in a STENTed human CORONARY ARTERY. In 3D simulations, .STENTs are assumed with real structure and modeled using the commercial software package (Gambit, V2.0). The blood flow was modeled as an incompressible Newtonian viscous fluid resulting in the Navier-Stokes equations. Rigid geometric boundary conditions were assumed for all simulations. The governing equations were solved using the commercial finite volume code (Fluent, V6.0.12). The results have shown that the wall SHEAR STRESS between STENT struts was sensitive to strut spacing, profile of strut, number of strut and curvature. In 3D models, the wall SHEAR STRESS distributions for different types of STENTs were calculated and critical regions were investigated. By application of a flow divider, the wall SHEAR STRESS in STENTed segment increases markedly.
