May inform AV biomechanical simulations; leaves open experimental validation before clinical use.
A newly developed transverse isotropic viscoelastic constitutive model accurately predicts the stress-deformation behavior of aortic valve tissue under physiological deformation rates.
Anssari-Benam et al. (2017) studied Aortic valve tissue mechanics. Transverse isotropic viscoelastic constitutive model vs. Experimental data was evaluated on Stress-deformation curves. A new transverse isotropic viscoelastic constitutive model provided an excellent fit to experimental stress-deformation data of porcine aortic valve tissue across different deformation rates.
