HA classification of fiber tracts limited in length to a ROI placed in the lateral wall of the LV (A) . Myofiber tracts in normal human (B-D), sheep (E-G), and rat (H-J) hearts have been reconstructed. The hearts are being viewed from the epicardial surface (red fibers) of their lateral walls and their fiber organization is well visualized with the discrete (B, E, H) median (C, F, I) and mean (D, G, J) HA classifications. The transmural variation in HA is highly similar in all three species.
