 Atrioventricular septal defects (AVSD) are congenital heart conditions marked by varying degrees of atrial and ventricular septal defects and a shared or partially separated atrioventricular orifice. A partial AVSD involves specific features like an atrial septal defect, separate atrioventricular valves with a common junction, a ventricular septal defect, and a cleft mitral valve. On the other hand, a complete AVSD features a common atrioventricular valve with an atrial septal defect and an unrestricted inlet-type ventricular septal defect. The clinical presentation of AVSD depends on the type of defect, the size of the intracardiac shunt, and any accompanying heart malformations. Complete AVSD patients often show signs of pulmonary congestion and right heart failure early in life due to a substantial left-to-right shunt, significantly as pulmonary vascular resistance decreases after birth. Heart failure and Eisenmenger syndrome might develop earlier in cases with atrioventricular...
