==Overview==
[[Apical]] displacement of the anterior [[tricuspid valve]] leaflet can be seen.'Atrialized' proximal portion of [[right ventricle]]. This occurs due to anterior displacement of [[tricuspid valve]] leaflet.[[Tricuspid regurgitation]] presenting as [[paradoxical septal motion]]. In Ebstein's, the [[tricuspid valve]] closes 50 to 60 msec after the [[mitral valve]].

==Fetal Echocardiography==
[[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]]

==Echocardiographic Findings==

*[[Apical]] displacement of the anterior [[tricuspid valve]] leaflet can be seen. 
* '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 echocardiography|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 valves|tricuspid valve]]. Note substantial [[tricuspid regurgitation]], which originates close to the apex, where the abnormal leaflets actually coapt:
