Tetralogy of Fallot associated with a rare type partially anomalous pulmonary venous connection and levoatrial cardinal vein.

Tetralogy of Fallot is rarely associated with partially anomalous pulmonary venous connection. Unidentified partially anomalous pulmonary venous connection, however, might increase the risk of pulmonary valve replacement in repaired tetralogy of Fallot patients. Here, we present a case of a 19-year-old male who received a correction of tetralogy of Fallot 18 years ago and a rare type of partially anomalous pulmonary venous connection with levoatrial cardinal vein was identified during the follow-up period. The anomalous pulmonary veins were connected to the left hepatic vein and the right superior caval vein. Performing a pulmonary valve replacement, partially anomalous pulmonary venous connection was also corrected with a new approach using the venous plexus between the hepatic veins.
