Evaluation and extraction of the Accufix atrial J lead.

The Accufix (Telectronics Pacing Systems, Englewood, Colo.) atrial active fixation pacemaker lead has a preformed J stiff retention wire that can fracture and erode through the atrium. We screened 85 patients with digital fluoroscopy and detected 18 (21%) lead fractures. Fourteen (16%) leads were successfully extracted by percutaneous techniques. The mean time for extraction and placement of a new atrial lead was 109 +/- 53 min, and a lead > 1 year old but not in the presence of a fracture was associated with a significantly longer extraction time. There were two extraction complications. One patient had a fever following the extraction, and one patient had a focal sensory deficit 1 week after the extraction probably caused by a paradoxical embolus. Standard percutaneous extraction tools can be used for successful and safe removal of a fractured Accufix lead.
