A voluntary recall of the Telectronics Accufix models 330-801 and 329-701 "J"-shaped atrial pacemaker leads has been issued because of fracture and extrusion of the J-shaped retention wire. Such extrusion can result in laceration of the atrium or surrounding vascular structures. Herein we describe a patient with a fractured and extruded retention wire that was snared and removed percutaneously; the atrial lead was left intact, and pacing function was satisfactory. This unique procedure can be used to avoid the morbidity associated with percutaneous lead extraction or thoracotomy and to prevent potential dislodgment and embolization of the retention wire during lead extraction.
