Summary

We studied the blood flow in the left ventricle of the human heart using a realistic Computational Fluid Dynamics (CFD) model. The CFD model was constructed from two-dimensional ultrasound echocardiogram data. An ultrasound image was sampled and smoothed by our own software system, which smoothes the obtained contour of the ventricular cavity using a cubic spline function. The time course of the contraction and dilatation of the left ventricle was also smoothed using the cubic spline function. Thus a time series of ventricular CFD models was established and CFD computation was performed using these models. With the simulated ventricular wall motion, we were able to visualize the diffusion of the blood inflow jet, which is reported to be important in the diagnosis of dilated cardiomyopathy.
