Atypical total anomalous pulmonary venous connection: two channels leading to infracardiac terminations.

Reported is a rare case of total anomalous pulmonary venous connection (TAPVC) where veins from each lung joined a homolateral confluence. From each confluence, a vein descended into the abdomen, the vein from the right lung joining the ductus venosus, while the vein from the left joined the portal vein. In TAPVC to systemic veins, multiple connections are rare. Multiple connections are most common at supracardiac and cardiac levels, less common at supra- and infracardiac levels, and rare at cardiac and infracardiac levels. From the literature, it is evident that multiple connections at one body level, as in our case, are rare.
