Heart diseases cause considerable morbidity and the prognosis after heart failure is poor. An improved understanding of cardiac mechanics is necessary to advance the diagnosis and treatment of heart diseases. This paper presents techniques for visualizing and evaluating biomedical finite element models and demonstrates their application by using as an example models of a healthy and a diseased human left ventricle. The following contributions are made: we apply techniques traditionally used in solid mechanics and computational fluid dynamics to biomedical data and suggest some improvements and modifications. We introduce a novel algorithm for computing isosurfaces for scalar fields defined over curvilinear finite elements. We obtain new insight into the mechanics of the healthy and the diseased left ventricle and we facilitate the understanding of the complex deformation of the heart muscle by novel visualizations.
