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

Echocardiographic Findings

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:

ACC/AHA 2018 Guidelines for the Diagnostic recommendations of Adults With Ebstein Anomaly(DO NOT EDIT)[1][2]

Class IIa
1.. In adults with Ebstein anomaly, TEE(transesophageal echo) can be useful for surgical planning if TTE(transthoracic echo) images are inadequate to evaluate tricuspid valve morphology and function. (Level of Evidence: B)
