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.
Accufix（泰利特罗尼克斯起搏系统公司，科罗拉多州恩格尔伍德）心房主动固定起搏器导线有一个预成型的J形硬固定导线，该导线可能会断裂并穿破心房。我们用数字荧光透视法对85例患者进行筛查，检测到18例（21%）导线断裂。14例（16%）导线通过经皮技术成功取出。取出并植入一根新的心房导线的平均时间为109±53分钟，导线使用超过1年但未发生断裂的患者，其取出时间明显更长。有两例取出并发症。一名患者取出后发烧，一名患者取出1周后出现局灶性感觉缺失，可能是由反常栓塞引起的。标准的经皮取出工具可用于成功、安全地取出断裂的Accufix导线。
