Closure of multiple fenestrations in an aneurismal atrial septum using overlapping GORE HELEX septal occluders.

Complex atrial septal anatomy can continue to present a challenge for transcatheter closure. We present the successful use of overlapping GORE HELEX atrial septal defect occluders in an adult patient with five distinct fenestrations in an aneurismal septum and how 3D echo can aid device positioning.
