This paper describe a simulation tool for estimating pre- and postoperative cardiac functions for a diseased heart due to myocardial infarction. Cardiac function is able to be evaluated obviously by a pressure-volume (PV) loop including Emax, computed based on FEM. For a normal model, a left ventricular finite element model is built from patient's cine CT images. It is assumed that the ventricular wall of the model is of one-layer, elastic and isotropic. An infarcted region set up for the left ventricular wall with abnormal Young modulus is removed to estimate the postoperative cardiac function in terms of PV loop. In our simulation, realistic trends of a PV loop are computed. The method of its online use using a multidimensional spline interpolation is presented.
