Inhomogeneity in collagen organization within the fibrotic scar. The scheme represents the organization of collagen fibers within the fibrotic scar. The fibers in the core area are arranged in an almost parallel manner. However, the collagen fibers are randomly organized in the outer areas. Images stained with picrosirius and photographed using a polarizer filter at 20× magnification represent collagen organization in the core area (1), endocardium (2), epicardium (3) and peripheral area (4).
