About Video

This video clip two-dimensional transthoracic echocardiography shows Ebstein’s anomaly. Apparent apical displacement of the attachment of septal leaflet (S) of the tricuspid valve (TV) as compared to the mitral valve (MV) is seen in apical four-chamber view. This displacement is related to tethering of the septal leaflet to the interventricular septum resulting in a bubble-like appearance. The septal leaflet in this patient and in almost all other patients with Ebstein’s anomaly actually originates normally from the atrioventricular junction.
