Abstract
In 7 human cases of Ebstein''s anomaly the right cineangiogram disclosed a big right atrium, the tricuspid valve positioned to the left of the spine and tricuspid regurgitation. The right atrial appendage was nearing the outflow tract of the right ventricle and pulmonary artery; thus the normal U appearance of the right angiograms was abolished. A very characteristic and almost pathognomonic rocking motion of the radiopaque material, moving from the right atrium towards the right ventricle during ventricular diastole and backwards to the atrium during the next ventricular systole, was observed. This sequence of motion gives the impression of a rocking hammock or pendulum.
