Transcatheter occlusion of baffle leaks following atrial switch procedures for transposition of the great vessels (d-TGV).

Baffle-related complications following atrial switch procedures for transposition are relatively common. Transcatheter treatment of baffle stenosis has an established role as a therapeutic modality. However, transcatheter device closure of atrial baffles leaks has rarely been reported. We report four patients who underwent device closure of baffle leaks using the Amplatzer septal occluder following atrial switch procedures in order to demonstrate the safety and utility of this method of treatment and to establish its role as a suitable alternative to surgical closure.
