Figure 6: Right ventricular perspective of the three types of ventricular septal defects classified according to their borders. Muscular defects (yellow) are located anywhere in the ventricular septum. Perimembranous defects (orange) have the atrioventricular conduction bundle (red) in the posteroinferior margin. Doubly committed and juxta-arterial defects (green) have the aortic and pulmonary valves forming the superior border.
