The left ventricle (LV) hemodynamics is great important in determining the condition of the whole human circulatory system. It is known that the LV functional performance is determined by the intraventricular fluid dynamics under the influence of the LV morphology. However, flow patterns in LV are always extremely complex and difficult to be fully understood by medical measurements. Therefore we have built up a variety of 3D-LV models for each beat cycle based on Ultrasound images and have established a multi-scale computational biomechanical model that couples a three-dimensional computational fluid dynamics (CFD) LV model with a global lumped cardiovascular system model. This LV simulator is capable to predict the LV functions in health and disease. In this study we report some preliminary numerical results about how the morphology and hence the LV functions of a patient change with time.
