Transthoracic echocardiographic examination: A Parasternal long axis view illustrating a large malalignment-type VSD (red arrow), and an aorta overlapping the interventricular septum. B Parasternal short axis view illustrating the VSD (red arrow) and a hypoplastic main pulmonary artery (blue arrow). C Continuous Doppler objecting severe right ventricular outflow tract stenoses (Vmax = 6.3 m/s). D Apical four chamber view illustrating a moderately dilated right ventricular (basal diameter = 43 mm). E Apical 5 chamber view illustrating the VSD (red arrow) and the overlapped aorta. F Color Doppler objecting bidirectional flow across the VSD. Ao: Aorta; LV: left ventricular; RV: right ventricular; and VSD: ventricular septal defect
