Figure 3. Initial myofiber orientation in SIT simulation MID.

Figure 3

A: Long-axis cross-section of LV mesh. B: Mapping of the cross-section in A on a rectangular domain used to describe the spatial distribution of myofiber orientations. The transition from a normal (SS) pattern at the apex to an inverted (INV) pattern at the base is described by parameters Inline graphic (location of transition at midwall), Inline graphic (the slope of the transition between the endo- and epicardium), and Inline graphic (the height of the transition zone). Inline graphic is subject of variation in between the SIT simulations BASE, MID and APEX. C: Initial (before reorientation) transmural course of helix angle Inline graphic in simulation MID (solid) at the 7 levels indicated in A. In the transition zone, the courses of the SS (− −) and inverted pattern (−.) are presented. The transmural distribution of the transverse angle Inline graphic was set to zero.
