The aim of our investigation was to test the suitability of a novel method for the analysis of the integrity of an explanted pacemaker lead stabilized by a stent. A coronary sinus lead has been explanted 27 months after implantation and has been examined by optical-, confocal-, x-ray-, and scanning electron microscopy. Several surface injuries were found on the insulation. Based on the surface characteristics, it is possible to define and differentiate the source of damages as well as to measure the extent of injuries. Impedance of the explanted lead has also been measured and electronic integrity has been verified.
我们研究的目的是测试一种新型方法的适用性，该方法用于分析由支架固定的植入式起搏器导线的完整性。一根冠状窦导线在植入27个月后被取出，并通过光学显微镜、共聚焦显微镜、X射线和扫描电子显微镜进行了检查。在绝缘层上发现了几处表面损伤。根据表面特征，可以确定并区分损伤的来源，以及测量损伤的程度。还测量了取出导线的阻抗，并验证了其电气完整性。
