We report the first-in-human retrieval of a chronically implanted Micra transcatheter pacing system (TPS; Medtronic, Minneapolis, MN, USA). A 41-year-old woman suffering from third-degree atrioventricular block was successfully implanted with a TPS in the low septum of the right ventricle. After 29 months, due to an increased electrical threshold and 100% pacing percentage, the device showed low battery voltage. Despite the long implant duration, the attempt of device retrieval using a snare loop inserted in the delivery system of a TPS was successful. In the same procedure, a new leadless pacemaker was implanted in the high right ventricular septum with optimal pacing threshold.
我们报告了首例人体取出长期植入的Micra经导管起搏系统（TPS；美敦力公司，美国明尼苏达州明尼阿波利斯）。一名患有三度房室传导阻滞的41岁女性在右心室低间隔成功植入了TPS。29个月后，由于电阈值升高和起搏百分比达100%，该装置显示电池电压低。尽管植入时间长，但使用插入TPS输送系统的圈套器成功取出了该装置。在同一手术中，在右心室高间隔植入了一个新的无导线起搏器，起搏阈值最佳。
