Description

Anatomy of the atrioventricular septation complex in a human four-chambered heart with normal anatomy and in hearts with AVSDs. (A) shows a properly septated heart with a complete atrial and ventricular septum. (B) depicts a heart with an incomplete AVSD, and in (C) a heart with a complete AVSD is shown. Note that when a primary atrial septal defect is observed, the muscular rim at the base of the atrial septum is missing. IVS = interventricular septum, pAS = primary atrial septum, pASD = primary atrial septal defect, LA = left atrium, LV = left ventricle, RA = right atrium, RV = right ventricle, VSD = ventricular septal defect.
