Abstract :
The curvature of the cardiac geometry has a major impact on regional wall stress, but most computational models lack detailed curvature representations. A surface with continuous second-order derivatives is required to model continuous curvatures. The goal of this research was to develop a mouse epicardial geometry model with quantitative surface curvatures.
