[Unusual manifestations of Ebstein's disease in a 53 year old adult. Ebstein's disease in an adult].

B.P., asymptomatic until her fifties, was admitted to hospital because of precordial pain. Her ECG and chest X rays were normal. When 52 she was again admitted, because of congestive heart failure. ECG showed repolarization abnormalities and chest X rays showed marked cardiomegaly. 2d echocardiogram was consistent with right atrial dilatation, dislodged posterior leaflet of the tricuspid valve and marked tricuspid regurgitation; these features were consistent with Ebstein anomaly. The patient was successfully treated by digitalis and diuretics. This case shows that in very rare cases this congenital heart disease can produce its clinical manifestations only late in lifetime.
