Three-dimensional numerical simulation of blood flow in two coronary stents

Three-dimensional numerical simulation of blood flow in two coronary stents
Three-dimensional numerical simulation of blood flow in two coronary stents

The aim of the present study is to perform computational fluid dynamics (CFD) simulations of blood flow in two coronary stents in a realistic three-dimensional geometry under physiological conditions. The two stents, similar to real coronary ones, are both made of 12 rings but are different as far as the positions of the struts are concerned. One type of stent has parallel-connectors and the other transverse-ones. Time variation of the parameters correlated to neo-intimal hyperplasia, such as wall shear stress, magnitude of wall shear stress gradient, and oscillatory shear index are investigated with the conclusion that the stent with parallel-connectors has a better fluid dynamic behavior.

Abstract

The aim of the present study is to perform computational fluid dynamics (CFD) simulations of blood flow in two coronary stents in a realistic three-dimensional geometry under physiological conditions. The two stents, similar to real coronary ones, are both made of 12 rings but are different as far as the positions of the struts are concerned. One type of stent has parallel-connectors and the other transverse-ones. Time variation of the parameters correlated to neo-intimal hyperplasia, such as wall shear stress, magnitude of wall shear stress gradient, and oscillatory shear index are investigated with the conclusion that the stent with parallel-connectors has a better fluid dynamic behavior.
