A Congenital heart defect characterized by a hole or shunt, developing between the two chambers of the heart. This allows increased blood flow returning to the lungs instead of being directed to the rest of the body through the aorta. The long-standing intracardiac shunt is caused by ventricular septal defect and atrial septal defect, or patent ductus arteriosus, causing cyanotic heart defect.
This condition can be detected in fetal echocardiography, or echocardiography early in life.
Cause(s) :
Ventricular septal defect
Atrial septal defect
Patent ductus arteriosus
Atrioventricular canal defect
