Figure 12: The anatomic image (left hand panel) and the echocardiograms (middle and right hand panels) are from different patients. They show how an atrioventricular septal defect with common atrioventricular junction can be arranged to permit only ventricular shunting when the bridging leaflets of the common atrioventricular valve are fused to the leading edge of the atrial septum. The right hand panel, in the short axis, confirms the trifoliate arrangement of the left atrioventricular valve
