Figure 17: The anatomic image (left hand panel) and the three-dimensional echocardiograms (right hand and middle panels) show how the typical defect seen in the setting of the common arterial trunk is also directly juxta-arterial. In the images shown, there is again a muscular bar interposing postero-caudally between the leaflets of the truncal and tricuspid valves. The defect itself opens to the right ventricle between the limbs of the septomarginal trabeculation or septal band (yellow Y)
