Figure 4: Echocardiographic parasternal short axis views at the level of the mid-left ventricle (LV). (a) The free wall of the right ventricle (RV) appears adherent to the adjacent pericardium (red arrows). There was note of septal bounce, leading to a D-shaped LV cavity during diastole. (b) M-mode of the same view confirmed the wavy motion (yellow arrows) of the interventricular septum representing septal bounce.
