Discussion of Ebstein's anomaly
- Characterized by varying degrees of dysplasia and displacement of the tricuspid valve leaflets into the right ventricle.
- The portion of the right ventricle into which blood flows fails to function normally, and the outflow tract functions as the main pumping apparatus of the right ventricle.
- Inferior displacement of tricuspid valve leaflets with enlargement of the right atrium and enlargement and dysfunction of the right ventricle are the classic features of Ebstein anomaly.
- The majority of patients have a concomitant patent foramen ovale or secundum atrial septal defect.
 Imaging Findings for Ebstein's anomaly
 Plain film
- Right atrial enlargement and right ventricular enlargement.
- The aorta is small, and the pulmonary trunk, which normally appears as a discrete convex bulge, is absent.
- The above combination of features produces a cardiac silhouette that has been described as box shaped.
 CT and MRI
- Inferior displacement of tricuspid valve leaflets with enlargement of the right atrium and enlargement and dysfunction of the right ventricle.
