From: Ventricular septal defect

Figure 3

In this heart, the right ventricle has been windowed, and the structures are viewed from the ventricular apex. As also seen in FigureĀ 2B, the aortic root overrides the crest of the apical muscular septum, and the greater part of the aortic root is supported within the right ventricle, with the antero-cephalad deviation of the muscular outlet septum producing subpulmonary infundibular stenosis. The specimen shows the tetralogy variant of hearts with double outlet from the right ventricle, but the red dots show the boundaries of the curved surface that is taken to represent the ventricular septal defect.
