Ebstein anomaly

Ebstein anomaly

Ebstein anomaly is a rare heart defect in which the tricuspid valve — the valve between the upper right chamber (right atrium) and the lower right chamber (right ventricle) of the heart — isn't formed properly. As a result, blood leaks back through the valve and into the right atrium. Atrial septal defect is a hole between the two upper chambers of the heart.
