Two-dimensional echocardiographic apical four-chamber view showing Ebstein anomaly

Two-dimensional echocardiographic apical four-chamber view (A) from a patient with Ebstein anomaly shows marked apical displacement of the septal tricuspid leaflet compared with the anterior mitral leaflet (asterisk). Note the large right atrium (RA). There was associated severe tricuspid valve regurgitation (TR) evidenced by color-flow Doppler (B).
