Total Anomalous Pulmonary Venous Drainage

  • The Pulmonary Veins, which carry blood back to the heart after it has circulated through the lungs, are not connected to the left atrium. Instead they are connected to one of the veins from the main circulation so that the blood returning from the lungs drains back to the right side of the heart. The affected babies may be blue or show signs of heart failure. Most of them require surgical repair in the newborn period.
