Echocardiogram
Fetal echocardiography helps in intrauterine diagnosis of Ebstein's anomaly
Two-dimensional echocardiography along with Doppler ultrasonography helps in making a diagnosis of Ebstein's anomaly. Echocardiography helps in
- Identifying the lesion,
- Determining the severity of dilatation of the right atrium
- Finding other associated cardiac defects that may be present.
- Finding the functional status of the tricuspid valve as well as the right ventricle
Findings on echo are-
- Apical displacement of the anterior tricuspid valve leaflet
- 'Atrialized' proximal portion of right ventricle. This occurs due to anterior displacement of tricuspid valve leaflet.
- Tricuspid regurgitation presenting as paradoxical septal motion.
- Patent foramen ovale or atrial septal defect may present as right to left shunting.
- Normally the tricuspid valve closes within 30 msec of the mitral valve. In Ebstein's, the tricuspid valve closes 50 to 60 msec after the mitral valve.
- The delayed tricuspid closure is not due to RBBB because it also occurs with preexcitation.
- 2D ECHO allows you to assess whether the repair can be accomplished without a prosthetic valve, and detects whether an interatrial shunt is present.

Below is an apical 4-chamber transthoracic view, showing apically-displaced leaflets of the tricuspid valve. Note substantial tricuspid regurgitation, which originates close to the apex, where the abnormal leaflets actually coapt:
