Abstract

To complement laboratory research, a computer program has been developed to solve the three-dimensional Navier-Stokes equations for time-dependent flow in a compliant thin-walled, anatomically correct left ventricle. This program is written in Fortran, and is currently running on a Cray Y-MP. Model parameters were selected so that the simulation results could be compared to clinical data. The results of this study show that the thin-walled, three-dimensional left ventricular model simulates observed normal heart phenomena. Validation of this model permits further studies to be performed which involve altered ventricular function due to a variety of cardiac diseases
