Abstract

We evaluated the stress distribution in a geometrical shape model and a shape model obtained from human heart using two different fiber orientations. For both orientation models, the results showed large differences of the stress distributions between the mathematical shape model and the measurement based shape model. These results suggest that stress distribution is highly dependent on the model geometry and the usage of a measurement based shape model is important for the evaluation of the left ventricular (LV) wall stress distribution. This fact may have some influences on the reported homogeneity of stress distribution with anatomical fiber orientation model that uses mathematical shape model.
