Oxygen rich blood keep circulating in the lungs repeatedly and deoxygenated blood through whole body causing a bluish discoloration. This becomes evident immediately after birth.

The most important tool for diagnosis is echocardiography by an experienced pediatric cardiologists . This defect can be diagnosed by fetal echocardiography before the child is born.

Immediately after diagnosis, a medication called Prostaglandin is started intravenously to keep the ductus open .If not possible a hole in the two receiving chamber (atrial septal defect) may be created by balloon catheter. However a surgical technique called arterial switch procedure brings the permanent relief. This should be done within 21 days after birth if there is no major communications between two chambers of the heart. The child usually grows normally after corrective surgery.
