Describes an extremely rare congenital cardiac anomaly involving bilateral Ebstein-like displacement of atrioventricular valves and an atrial septal defect.

May prompt consideration of bilateral Ebstein-like anomalies in ASD patients; extends the documented spectrum of atrioventricular valve malformations.
We report an unusual congenital cardiac anomaly consisting of a downward displacement of all leaflets of both atrio-ventricular valves. In addition to these changes, an atrial septal defect of the secundum type was noted. In light of the extreme rarity of this interesting anomaly complex, we reviewed the literature and compare the morphologic features of the present case with classic Ebstein's anomaly.
