This talk will describe recent progress towards the development of a comprehensive fluid-structure interaction (FSI) model of the human heart that is based on the immersed finite element-difference (IFED) method, which is an extension of the immersed boundary (IB) method. The talk will provide an overview of key aspects of the simulation methods as well as the anatomical and physiological models. It also will investigate physiological aspects of the integrative model, demonstrating that the FSI heart model yields realistic cardiac output, stroke volume, and pressure-volume loops, and that it automatically captures important features of the cardiac cycle, such as isovolumetric contraction and relaxation.
