Abstract

In this work it is presented a numerical simulation of the left ventricle hemodynamic behaviour of a human heart during its normal activity. For this purpose, a numerical model including both the endocardial structure and the fluid field has been created. It uses the fluid-structure interaction in order to simulate the pulsatile fluid flow produced by the cardiac chambers. The ventricular contractions imposed on the ventricular structure were obtained from experimental in vivo studies, and they describe both the radial contraction and the wringing of the chamber. The analysis determined the pressure and velocity field wich is produced into the ventricle at the different instants of the cardiac activity, showing various hemodynamic mechanisms acting into the ventricular chamber, especially associated with the loads acting on the heart valves. The comparison of this model with rigid ventricle models, often used in the past literature, demonstrates the inadequacy of the latter in describing the fluid-dynamic behaviour satisfactorily.
