Total Anomalous Pulmonary Venous Return (TAPVR) occurs when the pulmonary veins bring oxygen-rich blood from the lungs back to the right side of the heart, instead of the left side of the heart, where it most commonly gets delivered in healthy individuals.
This condition must be corrected with surgery. The surgery may be done in the newborn period if the infant has severe symptoms. If it is not done right after birth, it is done in the first 6 months of the baby’s life.
TAPVR repair requires open-heart surgery. The pulmonary veins are routed back to the left side of the heart, where they belong, and any abnormal connections are closed.
If a PDA is present, it is tied off and divided.
