Atrioventricular septumAtrioventricular septum - definitionAtrioventricular septum, or AV septum, refers to a division between two tissues or cavities (or cardiac septum) between the right atrium (RA) and the left ventricle (LV) of the heart. It is a tiny part of the membranous septum of the cardiac region.
Atrioventricular septum - locationThis structure is located in a position just higher to the septal cusp of the cardiac section known as the tricuspid valve.
Atrioventricular septum - anatomyThe structure is constituted by a membranous section and also a muscular section. The dorsal and the ventral AV cushion unite to form this section.
Atrioventricular septum - functionThe human body primarily requires this cardiac structure to act as a point of division between the left ventricle (LV) and the right atrium. The atrioventricular canal is divided by this structure.
Atrioventricular septum - defectsThere can be various defects in the AV septum, like ostium primum. Such problems may originate due to incomplete maturation of the endocardial cushions.
