Nine patients with Ebstein's anomaly of the tricuspid valve were studied by
two-dimensional echocardiography, using the standard long and short axis
views as well as the apex four chamber view. With this latter view, the
displacement of the tricuspid valve into the right ventricle was clearly
seen in all nine cases of Ebstein's anomaly and was not noted in a control
population. The severity of the tricuspid displacement was assessed by
comparing the position of the mitral and tricuspid valves relative to the
cardiac apex. The apex four chamber view allowed visualization of the
atrioventricular (AV) ring simultaneously with the displaced tricuspid
valve, and therefore the size of the "atrialized" right ventricle, true
right ventricle and right atrium could be determined. These dimensions
compared favorably with angiography.
