title = "Numerical model for the left ventricle pump: From the excitation of the fibers to the contraction of the whole heart",
abstract = "A model for the left ventricle is formulated that takes into account the mechanics of the wall considered as a pressurized thick ellipsoidal shell made of a composite fibrous and active medium. The activation of the fibers is heuristically introduced through the rheological properties of the muscle cells. The biphasic medium is anisotropic and nonhomogeneous, and the pitch angle of the fibers embedded into the interstitial matrix varies with their localization within the wall. Drawing from canine experimental data the geometrical and rheological input parameters of the model, a finite difference analysis applied to the equilibrium of the structure permits the determination of local agreement with ultrasound measurements, and the model predicts the overall kinematics of the left ventricular structure as recorded for wall thickness, major and minor axis diameter and volume of the cavity.",
