Transcatheter closure of long tubular patent arterial ducts: The Amplatzer Duct Occluder II-A new and valuable tool.

Despite the wide variety of occlusion devices available for closing the patent ductus arteriosus; some defects with unusual morphology still remain a challenge. The drive for increasingly user friendly and lower caliber delivery systems is also ongoing. The new amplatzer ductal occluder II may prove to be a useful additional tool in these circumstances. We describe our initial experiences with this new device in three patients with long tubular (Type C) ducts.
