The effect of stretching on transmural shear wave anisotropy in cardiac shear wave elastography

Abstract
Shear Wave Elastography (SWE) is a potential tool for non-invasively assessing myocardial stiffness to support diagnosis and treatment choice in patients with cardiac disorders. Previous studies demonstrated a 3D anisotropic shear wave propagation in cardiac SWE due to the intrinsic myocardial fiber architecture. The aim of this work is to further investigate the performance of cardiac SWE by studying the effect of uniaxial stretching on anisotropic shear wave propagation and characterization. Results showed a clear increase in group and dominant phase speed during stretching, especially along the direction of the fiber. Additionally, the maximal group and dominant phase speed value spatially shifted while stretching, indicating an alignment of the fibers to the stretching direction. Complementary numerical modeling could further explore these interactions between myocardial fiber architecture and cardiac loading during SWE.
