Figure 6
Schematic representation of sectoral distributions for quantitative analyses and transmural distributions of helical angles (HA). (Top) Regional myocardial segmentation identifying (left) basal, middle, and apical areas, (middle) left ventricular (LV) anterior, lateral, inferior and septal areas, and epicardial to endocardial areas (Epi, Epi-Mid, Mid-Endo, Endo); (right) sectoral representation for HA profile analyses. (Bottom) Plots of transmural helical angle trajectories in middle-myocardium, based on sectoral analyses.
