• Video 1 - Video 1 (.rv format). This demonstrates a moving three-dimensional echocardiographic example of a patient with Ebstein’s malformation. The first clip shows the tricuspid valve viewed from the ventricular apex. Note the poorly formed septal leaflet, and large coaptation failure with the antero-superior leaflet, forming a ‘keyhole’ defect. The second clip shows the valve viewed in the ventricular long axis plane. Note that the tricuspid valve is seen in its short axis, whilst the mitral valve is seen in its long axis, demonstrating the rotational abnormality that is key in this malformation.
