CTICasesPersistent Levoatrial Cardinal Vein
Imaging findings
CT angiography shows a persistent vertical vein running lateral to the aortic arch, connecting the left atrium directly to the left brachiocephalic vein. Left-sided venous anatomy is otherwise normal.
Key takeaways
A persistent levoatrial cardinal vein is a rare congenital anomaly representing a venous channel connecting the left atrium or pulmonary veins to the systemic venous system. It acts as a left-to-right shunt and can simulate a persistent left SVC, but is anatomically distinct as it drains directly into the left atrium.
