Atrioventricular septal defects (AVSD) result from abnormal development of the membranous and muscular atrioventricular septum. Depending on severity, the defect can be classified as complete or partial. The ventricular septal defect is located at the 'inlet' portion of the ventricle and the atrial septal defect occurs as an ostium primum type (a deficiency of the septum primum in its inferior and anterior aspect). AVSD can accompany other complex congenital heart disorders.
