Ebstein's anomaly is a defect of the tricuspid valve, which separates the right atrium from the right ventricle. The valve is displaced into the right ventricle, which gets enlarged, causing it to work poorly. Because the tricuspid valve's defect, the valve does not close entirely and blood leaks back into the right atrium.

Ebstein's anomaly may also can also include abnormal heartbeats and holes in the heart.
