| Abstract: | 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. (PACE 2013; 36:e27–e30) |
