Ebstein's anomaly is a disorder where there is apical displacement of the tricuspid valve leaflets (predominantly the septal and posterior leaflets) causing "atrialization" of the right ventricle. Here the apical 4 chamber view shows the anomaly well. Note how apical the tricuspid valve is compared to the mitral valve. Frequently there is an associated ASD.

A zoomed in view of the tricuspid valve shows shows clearly how the septal leaflet is more more apically displaced than the mitral leaflets.

The color window is also added here to help you better discern where the tricuspid leaflets coapt. Note there is some TR.
