Viscoelastic arterial models improve simulation fidelity in animals; leaves open human validation before clinical use.
Using a viscoelastic wall model in 1D fluid dynamics simulations provides more physiologic predictions of arterial pressure and deformation than simple elastic models.
Steele et al. (2011) studied this question. Viscoelastic wall model vs. Linear elastic wall model was evaluated on Prediction of arterial blood pressure and vessel deformation. Incorporation of a viscoelastic wall model allowed more physiologic prediction of arterial blood pressure and vessel deformation compared to simple elastic wall models.
