Leadless pacemakers provide safe and effective pacing options for patients with device-related infections. This study was aimed at observing and evaluating the safety and feasibility of extracting an infected pacemaker device followed by the implantation of a leadless pacemaker in the same location for patients without systemic infection.
Between December 2019 and September 2020, following a well-planned re-implantation strategy, pacemaker electrodes were removed from patients with device infection and leadless pacemakers were immediately implanted at our center. The patients were then followed up for up to 10 months to assess the safety and practicality of the procedure.
Pacemaker electrode removal and immediate leadless pacemaker implantation were successfully achieved in eight patients with pocket infection. After a minimum follow-up period of 1 month and a maximum follow-up of 10 months, the pacing parameters for the patients remained stable and there was no infection at the original capsular bag or in the leadless pacemaker.
Direct implantation of a leadless pacemaker is safe and feasible for patients with local infection of the pacing system after removal of the electrode as an alternative to a bridge period with a temporary pacemaker. This strategy may be a better option for pacing-dependent patients.
无导线起搏器为器械相关感染患者提供了安全有效的起搏选择。本研究旨在观察和评估对于无全身感染的患者，在移除感染的起搏器装置后，直接于同一部位植入无导线起搏器的安全性和可行性。
在 2019 年 12 月至 2020 年 9 月期间，根据精心制定的再植入策略，我们中心的医生从发生器械感染的患者体内取出起搏器电极，并立即植入无导线起搏器。然后对患者进行了长达 10 个月的随访，以评估该操作的安全性和实用性。
8 例囊袋感染患者成功地完成了起搏器电极的移除和即刻无导线起搏器的植入。在 1 个月至 10 个月的最短和最长随访时间后，患者的起搏参数保持稳定，原囊袋或无导线起搏器处均无感染。
对于移除电极后起搏系统局部感染的患者，直接植入无导线起搏器是安全且可行的，可替代临时起搏器桥接期。对于依赖起搏的患者，这种策略可能是更好的选择。
