CTICasesPersistent Levoatrial Cardinal Vein
Imaging findings
Chest CT angiography shows a left superior pulmonary vein with a dual connection: it communicates normally with the left atrium and anomalously with a vertical vein that drains into the left brachiocephalic vein, representing partial anomalous pulmonary venous return.
Key takeaways
A persistent levoatrial cardinal vein is a rare congenital vascular anomaly representing a connection between the embryologic pulmonary venous plexus and the systemic veins. In the presence of pulmonary hypertension or elevated left atrial pressures, this dual communication can cause hemodynamically significant left-to-right shunting or even paradoxical right-to-left shunting during transient pressure changes.
