Computed fractional flow reserve for coronary stenosis using computational fluid dynamics

Atherosclerosis has become one of the most common health problems in today's lifestyle. Our focus is on Coronary Artery Stenosis. Coronary Artery Stenosis is caused by narrowing of arteries, when there is formation of plaque on the walls of Coronary Artery. If not diagnosed at the early stage, the blockage could advance and might lead to stroke or even death. To diagnose the severity of stenosis, Fractional flow Reserve (FFR) value is taken into consideration. FFR value represents the amount of flow that could be achieved despite the presence of stenosis in the artery. Traditionally, FFR is measured using a specialized probe inserted through a catheter tube, and the technique is expensive. In our proposed work we tend to compute the FFR value through the non-invasive method by utilizing Computational Fluid Dynamics (CFD). FFR value could be calculated by the ratio of distal and proximal pressures to the stenosis. Improved Diagnostic Accuracy can be obtained by using the Computational Fluid Dynamics method. This could help the physician determine whether the patient requires angioplasty or not. As the proposed measurement is by non-invasive method, the patient can avoid Coronary Angiogram which is a painstaking process
