Ebstein's anomaly with recurrent massive pericardial effusion: a rare presentation.

Ebstein's anomaly is known for its varied presentations and exceptionally long survival in some cases. Here the authors describe a case of previously undiagnosed Ebstein's anomaly in a patient who presented with massive pericardial effusion. Over the next 6 months, the patient was hospitalised twice for pericardiocentesis. To the best of our knowledge, a case of Ebstein's anomaly with recurrent massive pericardial effusion has not been described previously.
