Finite Element Modeling of Left Ventricle

Abstract

Three-dimensional reconstructions of cardiac ventricular chambers can be obtained from two-dimensional echocardiographic and ultrafast computed tomographic images. Using finite element analysis of the reconstructed geometry, the deformation of the ventricular chambers and the stress distribution in the myocardium can be predicted. By performing the finite element analysis on a simulated model of the ventricular chambers, the importance of the interaction of the right and left ventricular chambers on the resulting deformation and stress distribution is discussed. Consideration of interventricular interactions and physiologically realistic boundary conditions should improve finite element modeling of left ventricular mechanics.
