Partial anomalous pulmonary venous drainage to persistent left superior caval vein: Or is it a "levoatriocardinal vein"?

We report a case of a 3-month-old girl with pulmonary atresia and intact ventricular septum where computed tomography (CT) angiography demonstrated an anomalous venous channel connecting the left brachiocephalic vein to the left atrium and all the pulmonary veins draining the left lung were seen draining individually into this channel. The case highlights the differential diagnosis of such veno-venous connections between the systemic and pulmonary venous circulations as well as the growing role of CT angiography in the understanding of these venous anomalies in the setting of complex congenital heart diseases.
