Histological examination of the basal inferoseptal (BIS) left ventricular myocardium. Histological slice (A) stained with Masson’s trichrome and corresponding anatomical image (B) and cFA maps (C) in the basal inferoseptal (BIS) left ventricular myocardium. Anatomical landmarks such as vessels having a black contrast are indicated with yellow asterisks. The red arrow and red asterisk indicate the location of the region depicting a triangular shape. Panels D–F show an enlarged view of the previous panels. Zoomed rectangle regions (G–L) are indicated and are located either inside the region (G), outside (H, I) or at the junction (J–L). The blue and gray arrows indicate cardiomyocytes in transverse and longitudinal direction respectively. The dash black lines indicate roughly the location of discontinuities in myocyte orientation
