We present a case of a 76-year-old woman on a permanent pacing device, with early abrasion of silicone endocardial lead insulations complicated by lead-dependent infective endocarditis 13 months after placement of an implantable pulse generator. The leads were removed using transvenous technique with direct traction, and with no additional tools. In the previous report, a set of additional tools was used, and therefore intraoperative endocardial lead abrasions or mechanical damage of leads could have not been excluded. The present case undoubtedly proves that the friction of leads against each other may result in abrasions of insulation of the intracardiac section of the lead.
我们报告一例76岁女性患者，其植入了永久性起搏装置，在植入可植入式脉冲发生器13个月后，硅胶心内膜导线绝缘层早期磨损，并并发导线依赖型感染性心内膜炎。采用经静脉技术直接牵引取出导线，未使用其他额外工具。在之前的报告中，使用了一套额外工具，因此无法排除术中的心内膜导线磨损或导线机械损伤。本病例无疑证明，导线相互摩擦可能导致心内段导线绝缘层磨损。
