What characterizes Ebstein's anomaly?

Ebstein's anomaly is primarily characterized by the displacement of the tricuspid valve leaflets towards the apex of the right ventricle. In this condition, the tricuspid valve is malformed, leading to an abnormal positioning where the valve is found lower than its usual location in the right ventricle. This displacement can lead to a range of complications, such as atrial enlargement, regurgitation, and associated symptoms arising from the impaired flow of blood through the right side of the heart. The anatomy is distinct from other cardiac anomalies, emphasizing the significance of this displacement as a defining characteristic of Ebstein's anomaly.
