An unligated vertical vein (VV) after TAPVC surgery is likely to require subsequent closure. Reports of transcatheter closure of the VV are largely unpublished. This report details transcatheter closure of a persistent VV using an Amplatzer PDA occluder, following TAPVC repair in early infancy. We suggest that transcatheter closure should be considered as a treatment option in this condition. (c) 2007 Wiley-Liss, Inc.
