Echocardiographic, anatomic, and histopathologic images of the ventricular wall. The right ventricular (blank arrow) and septal (white arrow) wall is thicker than the left ventricular wall (arrow head) on a right parasternal echocardiographic short axis image (a) and a transverse gross image showing irreversible septal flattening (b). c Histopathologic findings for the right ventricle stained with Masson’s trichrome protocols. Microscopic views at 200× magnification show fibrosis that is stained blue because of the collagenous tissues. RV, right ventricle; LV, left ventricle
