Figure 7: The anatomic specimen (left hand panel), and a three-dimensional echocardiogram from a different patient (right hand panel) show how, in a double outlet right ventricle, the interventricular communication is the effective outlet for the left ventricle (yellow dotted plane). Although often considered the ‘ventricular septal defect,’ it would be a disaster if this hole was closed surgically. Instead, the surgeon usually tunnels the interventricular communication to the aortic root (green dotted plane). It is this plane that should arguably be considered to represent the ventricular septal defect. Note that the muscular outlet septum is an exclusively right ventricular structure
