Abstract

Systolic epsilon and SR imaging indicate differences in the radial deformation in different layers of the interventricular septum, which might be explained by the complexity of the septal fiber arrays and function. It might also explain why using Doppler tissue imaging technique is limited in assessing radial myocardial septal velocities. Furthermore, these results suggest that longitudinal shortening dominates in the right ventricle whereas the radial shortening dominates in the left ventricle.
