Abstract

We present a numerical study of dynamical blood flow in a left ventricle of human heart using Computational Fluid Dynamics (CFD). Three-dimensional shape of the left ventricle model was reconstructed using spline interpolation, based on a set of two-dimensional ultrasound echocardiogram images. Blood flow in the left ventricle was computed by solving the incompressible, unsteady Navier-Stokes equations in a manner of Finite Volume Method (FVM). In the present preliminary results the asymmetric intracardiac flow pattern is detected very similar to observed in vivo (Kilner, 2000) which shows a large vortex and a small vortex at diastole.
