Figure 13. Selected video frames from a 2D echocardiogram in long (A) and short (B) axis views of an infant with transposition of the great arteries. Note the parallel position of the pulmonary artery (PA) and aorta (Ao) in A and on-end visualization of PA and Ao in (B). These echoes are highly suggestive of transposition of the great arteries; in a normal baby, because of the normal crisscrossing of the PA and Ao, such an appearance is unlikely. Reproduced from Ref.^[13]. LA: Left atrium; LV: left ventricle; RA: right atrium; RV: right ventricle.
