Abstract—Coronary artery disease is the most prevalent form of cardiovascular disease and is the largest subset of this mortality. Stent implantation becomes a common interventional procedure for treatment of coronary artery disease. In this study, fluid dynamics factors in patient specific three dimensional coronary artery models before and after stenting were studied. The three dimensional models of the coronary artery were constructed from CT image of the patient. Commercial software Adina was used for computational fluid dynamics simulation. The wall shear stress and blood velocity were greater at the region of stenosis before stenting. The fluid dynamics values have come back near to normal values in the coronary artery model fitted with stent. The technique can be employed to estimate the relevant quantities and to optimize the design of intravascular stents.
