Echocardiographic images at presentation from right parasternal short axis view. a Two-dimensional view demonstrating severe right ventricular (RV) dilation, flattening of the interventricular septum (IVS) and a hypovolemic left ventricle (LV). b M-mode view demonstrating severe right ventricular dilation, a hypovolemic left ventricle and paradoxical motion of the interventricular septum. c Two-dimensional view of pulmonary artery (PA) and aorta (AO). The PA is uniformly dilated and is wider than the Aorta with a PA/AO ratio of 1.3 (reference interval: 0.8–1.15)
