Though present in up to a quarter of adults a patent foramen ovale (PFO) has been implicated in a diverse range of medical conditions including cryptogenic stroke, migraine and decompression illness. A wide range of devices are available, each with different technical advantages that may favor particular anatomic features. We recently encountered a case of late-locking loop fracture following the use of a Helex septal occluder device (W.L. Gore and Associates, Flagstaff, Arizona) to close a PFO in a diver. This resulted in increased device mobility and continued interatrial shunting. Here we describe the successful stabilization of the original device by transcatheter insertion of a second, less compliant device through the residual atrial shunt.
虽然高达四分之一的成年人存在卵圆孔未闭（PFO），但其已被认为与多种医学病症有关，包括不明原因的中风、偏头痛和减压病。有多种装置可供使用，每种装置都有不同的技术优势，可能适用于特定的解剖特征。我们最近遇到一例在一名潜水员使用Helex房间隔封堵器装置（W.L. Gore and Associates，亚利桑那州弗拉格斯塔夫）关闭PFO后出现迟发性锁定环骨折的病例。这导致装置移动性增加和持续的心房分流。在此，我们描述了通过经导管将第二个顺应性较低的装置经残余心房分流插入，成功稳定了原始装置。
