FSI alters carotid WSS estimates versus rigid walls; leaves open whether it improves clinical atherosclerosis risk stratification.
Effect estimate: 5-11% difference
Fluid-structure interaction modeling of the carotid artery demonstrates significant differences in wall shear stress calculations compared to rigid models, which may better identify regions susceptible to atherosclerosis.
Taewon Seo (2013) studied this question. Fluid-structure interaction (FSI) model vs. Non-FSI model was evaluated on Difference in wall shear stress (WSS) (5-11% difference). A fully coupled fluid-structure interaction (FSI) analysis of a human carotid arterial bifurcation model demonstrated a 5 to 11% difference in mean wall shear stress compared to a non-FSI model.
