Abstract

This study simulates the effect of stenting in an image-based coronary model. Three-dimensional models of the coronary artery were created from computed tomography images of a coronary artery stenosis patient before and after stent implantation, and a realistic aorto-coronary differential pressure was imposed at the inlet of the computational vessels. The results show that the stent increased the flow rate several fold compared to that for the stenosis artery model, and that the hemodynamic values returned to near normal levels in the coronary artery model fitted with a stent. The results confirm that stenting significantly improves the hemodynamics of the artery.
