The SelectSecure catheter delivery system and active fixation 4.1 French diameter Model 3830 pacing lead (Medtronic, Inc, Minneapolis, MN, USA) has the advantage of permitting precise implant at nearly any desired location due to catheter maneuverability. However, as the lead lacks an internal stylet lumen, it is intrinsically floppy and any repositioning after the delivery catheter is removed is nearly impossible, necessitating lead extraction and a repeat of the implant process. At present, there are no commercially available tools to precisely reposition this lead. This report presents a simplified approach to reimplant a dislodged Model 3830 lead using currently available materials to create an effective maneuverable and removable encircling snare.
SelectSecure导管输送系统及4.1法国规格直径的主动固定型3830型号起搏导线(美敦力公司,美国明尼阿波利斯)具有优势,因其导管可操作性强,能够在几乎任何期望位置进行精确植入。然而,由于该导线缺乏内部引导钢丝腔,其本质上较为柔软,在移除输送导管后几乎不可能重新定位,这就需要拔出导线并重复植入过程。目前,尚无市售工具可精确重新定位该导线。本报告介绍了一种简化方法,即使用现有材料重新植入移位的3830型号导线,以制作一种有效的可操作且可移除的环绕圈套器。
