"A characteristic anatomic feature of the atrioventricular junction is the atrioventricular septum a septal component separating the right atrium from the left ventricle. It forms an offset of the atrioventricular annular anatomy with a length of up to 8 mm/m2 BSA between the more apically located septal tricuspid leaflet and the hinge of the anterior mitral leaflet 1-3. It consists of an anterior membranous and inferior muscular part evolving from the right atrial septal wall and an extension or the crest of the interventricular septum on the left with fibrous and adipose tissue from the inferior atrioventricular groove sandwiched in between the two muscular structures 1-5."
