Figure 56. Selected video frames from the parasternal long-axis (A) and subcostal four chamber (B) views of a patient with double-outlet right ventricle and normally related great arteries, demonstrating the origin of both the aorta (Ao) and the pulmonary artery (PA) from the right ventricle (RV). The ventricular septal defect (VSD) is shown. The vessel labeled as PA was shown to divide into right and left PAs, but not shown in the echo images. Reproduced from Ref.^[39]. LA: Left atrium; LV: left ventricle.
