Implication

Models using uniaxial parameters may underestimate multiaxial myocardial stresses; leaves open validated transversely-isotropic constitutive laws for cardiac biomechanics.

Population

Passive cardiac tissue (uniaxial papillary muscle and biaxial experimental data)

Intervention

Formulation of a three-dimensional constitutive relation using a structurally motivated pseudostrain-energy function

Outcome

Material parameters and stress predictions under multiaxial loadingsurrogate

A proposed pseudostrain-energy function demonstrates that multiaxially-loaded cardiac tissue behaves as nearly transversely-isotropic, highlighting the inadequacy of uniaxial data for predicting multiaxial stresses.
