title: Taming the "cobra": an approach to "cobra-like" formation seen in the Occlutech atrial septal defect and patent foramen ovale occluders.
abstract: Percutaneous closure of secundum atrial septal defect and patent foramen ovale has gained widespread use in recent years. We present a small series of four cases in which a "cobra-like" formation occurred in an Occlutech Figulla device during the deployment of the left disk, and propose a technique that may resolve this problem.
