Ebstein anomaly of the tricuspid valve

What it means

Ebstein's anomaly refers to an abnormally placed and deformed tricuspid valve characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle with a variable degree of malformation and displacement of the anterior leaflet.

Ebstein's anomaly is often associated with a hypoplastic right ventricle, patent foramen ovale, and a degree of cyanosis dependent on the amount if inadequacy of the tricuspid valve. Ebstein's anomaly may be associated with Wolf-Parkinson-White syndrome or other arrythmias.
