The exaggerated apical displacement of the septal and posterior leaflets of the tricuspid valve (TV) in tandem with leaflet dysplasia and adherence of the tricuspid valve leaflets to the underlying right ventricle (RV) myocardium are the diagnostic features of the Ebstein anomaly. Usually, in the normal heart, there is a 10 mm distance between the mitral annulus and tricuspid annulus. In the Ebstein anomaly, the apical displacement of the septal leaflet of the TV is 8 mm/m 2 or more, associated with elongated, tethered anterior TV leaflet [1–3].
