Experience using the new GORE® septal occluder at the margins

Complex atrial anatomy continues to challenge transcatheter device closure of septal defects. Devices and technology continue to evolve. We report three cases from our institution where the new Gore® Septal Occluder was utilized for the closure of a lateral tunnel fenestration, a moderate‐sized secundum atrial septal defect and a long tunnel patent foramen ovale. Each case highlights the successful use of this new generation device in challenging circumstances. © 2013 Wiley Periodicals, Inc.
