Error Analysis in Patient-Specific Blood Flow Modeling of Coronary Artery Disease

This paper reviews the methodological aspects related to the patient-specific blood flow modeling of coronary artery disease, aiming to identify and quantify the main sources of errors and trying to minimize them but also accelerate the computational process. It is envisaged to extend these multiscale modeling techniques to multiple-branches arteries, in which case the computation time becomes critical. The possibility of replacing these 3D multiscale models with the much faster 0D models is suggested. First, the multiscale model of a single-branch coronary artery is presented. Then, the 0D and 3D multiscale model of a multiple-branches artery are presented. Finally, the simulation results of these models are compared with each-other and their errors analyzed.
