A balanced variant of Ebstein's anomaly preserves tricuspid valve function through overgrowth of the septal leaflet, which allows for proper leaflet coaptation.
Describes a rare 'congenitally corrected' variant of Ebstein's anomaly with preserved tricuspid valve function due to septal leaflet overgrowth.

Recognizes balanced Ebstein variant preserving tricuspid function; leaves open natural history and management implications.
Ebstein's anomaly is a rare CHD that is characterised by caudal displacement of the functional tricuspid annulus and a dysfunctional tricuspid valve owing to a failure of proper leaflet coaptation. We present a balanced variant of Ebstein's anomaly, in which the overgrowth of the septal leaflet had allowed proper coaptation of the tricuspid leaflets, thus preserving the valve function.
