Ebstein's anomaly

Ebstein's anomaly is a congenital heart condition which results in an abnormality of the tricuspid valve. In this condition the tricuspid valve is elongated and displaced downward towards the right ventricle. The abnormality causes the tricuspid valve to leak blood backwards into the right atrium.
