Ebstein's anomaly: demonstration by ECG-synchronized radionuclide cineangiography.

The findings of radionuclide cineangiography in Ebstein anomaly are described. The subjective findings in this case were similar to those of radiographic angiography, and there was objective evidence of tricuspid insufficiency. It is useful to recognize that Ebstein's anomaly is present before cardiac catheterization, since the procedure carries a relatively high risk of death in patients with this disorder.
