Figure 2: The heart shown to the left hand has been prepared by sectioning in the four chamber plane and removing the non-coronary leaflet of the aortic valve. The three-dimensional echocardiogram, seen to the right hand, replicates the anatomic preparation, showing how the hinge of the septal leaflet of the tricuspid valve divides the membranous septum into atrioventricular (white arrow) and interventricular (red arrow) components
