Eustachian valve (arrow)

Case Discussion

The valve of the inferior vena cava (Eustachian valve) lies at the junction of the inferior vena cava and right atrium.

There is a large variability in size, shape, thickness, and texture of the Eustachian valve, and in the extent to which it encroaches on neighbouring structures such as the atrial septum.

Higher insertion of a giant Eustachian valve may mimic the echocardiographic appearance of divided right atrium, suggesting the diagnosis of cor triatriatum dexter.

In adults, it may be confused with right atrial tumors, thrombi, or vegetations.
