We evaluated the stress distribution in a cylindrical model and a shape model obtained from human heart using two different fiber orientations. For both orientation models, the results showed large differences between the stress distribution in the cylindrical 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 evaluating left ventricular (LV) wall stress distribution. This fact may have some influence on the reported homogeneity of stress distribution in an anatomical fiber orientation model that uses a mathematical symmetric shape model.
