For the cardiac plastic surgery, cardiac muscle palpation is certainly needed to determine the surgical plan. The opportunity to palpate the cardiac muscle is limited in the operative scene, so that the cardiac surgeons desire the training systems for cardiac muscle palpation. For building the cardiac muscle palpation training system, the virtual heart model which enables to give its mechanical elasticities to the trainees in real-time is necessary. The virtual heart is composed of cine CT imaging data for human beating heart, a simple systemic circulation system, and a set of the low dimension dynamic model for real-time processing. In order to identity the mechanical parameters of cardiac muscle, we measured the cardiac characteristics from animals' heart. The large deformation model will make our virtual heart more practical. The proposed virtual heart took a good evaluation from the cardiac surgeons.
