Figure 68. Apical four-chamber views of an echocardiogram of a baby with a mild to moderate form of Ebstein’s anomaly. Panel (A) shows a two-dimensional image demonstrating the insertion of the septal leaflet of the tricuspid valve (arrow), which is displaced apically in comparison to the insertion of the mitral valve. The atrialized right ventricle (aRV) is shown. Panel (B) shows a color Doppler image demonstrating moderate tricuspid valve regurgitation (TR). Reproduced from Ref.^[58]. LA: Left atrium; LV: left ventricle; RA: right atrium; RV: right ventricle.
