Distorsion du ventricule gauche et interaction ventriculaire

A theoretical study, based on physiopathological observations, is presented to understand the effect of the right ventricle (RV) on the kinematics and dynamics of the left ventricle (LV). Our results show: (i) for a given geometry, rheology, and trans-septal pressure gradient, the shape of the LV is more sensitive to the RV pressure than the LV pressure, and (ii) the isotropic collagen matrix is one of the main determinants of the LV shape
