Abstract:

It is of great physiological significance to simulate the behavior of diseased human arteries using computational methods, as it will help the clinicians in the early diagnoses of the disease. This paper reviews the comparison between the flow in a regular and a stenosed artery. It also reviews the application of Computational Fluid Dynamics (CFD), for simulating blood flow phenomenon in human arteries. The usage of the CFD in simulating and analyzing the anatomically realistic models are discussed. Various methodologies applied for assessing the effectiveness in predicting the behavior of blood flow in arteries is presented. The pressure gradient and flow velocities in the left coronary artery were measured and compared in the left coronary models with and without presence of plaques during cardiac cycle. Our results showed that the highest pressure gradient was observed in stenotic regions caused by the plaques. Low flow velocity areas were found at postplaque locations in the left circumflex andthe left anterior descending. There are direct correlations between coronary plaques and subsequent hemodynamic changes, based on the simulation of plaques in the realistic coronary models.
