Figure 69. An echocardiogram of another baby with Ebstein’s anomaly. Apical four-chamber views are shown. (A) Shows a two-dimensional image. (B) Shows the same image with color Doppler flow mapping. Note the significant downward displacement of the tricuspid valve (TV) attachment (solid arrow labeled “TV attachment”) from the true annulus of the tricuspid valve (marked by a dotted line). The portion of the right ventricle (RV) between the tricuspid valve annulus and the tricuspid valve attachment is the atrialized portion of the right ventricle (aRV). *Represents the location of the patent foramen ovale. The color Doppler image in B shows right to left shunting (blue color). Note the markedly enlarged right atrium (RA) in both (A) and (B). Reproduced from Ref.^[60]. LA: Left atrium; LV: left ventricle.
