Residual stress inclusion modestly shifts LV transmural stresses in animal models; leaves open its role in human mechanics and remodeling simulations.
Incorporating residual stress into a hyperelastic constitutive model of the left ventricle alters myocardial stress distributions, which may be important for future models of cardiac mechanics and remodeling.
Wang et al. (2013) studied Healthy (computational model) (n=1). Modified Holzapfel-Ogden model with residual stresses vs. Model without residual stresses was evaluated on Transmural stress distributions. Incorporating residual stress into the left ventricular model changed transmural stress distributions, decreasing endocardial stress and increasing epicardial stress, though overall effects were small.
