What is Ebstein’s anomaly? Cardiology Basics

Ebstein’s anomaly is a congenital anomaly of the tricuspid valve, which may manifest soon after birth or more commonly later in life. In Ebstein’s anomaly, two of the three leaflets of tricuspid valve are displaced further into the right ventricle. Usually anterior leaflet is not displaced while the septal and posterior tricuspid leaflets are displaced. So, a part of the right ventricle becomes part of the right atrium functionally and is called atrialized right ventricle. Undisplaced anterior leaflet is elongated.
