Abstract

A two-dimensional finite analytic technique is used to simulate left ventricular (LV) wall motion abnormality during systole. The numerical technique solves 2-D Navier-Stokes equations for viscous, incompressible, unsteady flow. The velocity profile within the chamber is obtained as the time-dependent wall motion is used as input. The areas of akinesis and diskinesis show backflow and low-velocity gradient at the wall. This may have implication in the formation of LV clot. A fluid-mechanical model may serve as an adjunct to the high-resolution imaging modalities capable of flow visualization of the contrast material.
