摘　　要：目的:评估没有起搏指征的静脉埋藏式心脏复律除颤器(TV-ICD)患者经静脉导线拔除(TLE)后植入全皮下埋藏式心脏复律除颤器(S-ICD)的安全性和有效性。方法:连续纳入2018年6月至2023年10月于北京大学人民医院行TLE后再植入S-ICD的所有患者。统计并分析TLE指征、S-ICD植入适应证、除颤阈值(DFT)测试、并发症及术后随访情况。结果:共有11例TV-ICD患者在TLE后接受了S-ICD植入,男性8例,中位年龄56(44,65)岁。TLE的指征为感染和导线功能障碍。ICD二级预防的有9例患者,最常见的植入原因是离子通道疾病(5例)。S-ICD的手术时间为51(48,58)min,未发现围术期并发症。8例患者进行了DFT测试,全部成功。在中位30(9,39)个月的随访中,2例患者共发生6次适当的治疗,无并发症发生,包括不适当的治疗、无效治疗、感染、导线故障和死亡。结论:本研究为S-ICD作为TV-ICD移除后的替代提供了依据。TLE后植入S-ICD是安全有效的。Objectives:To evaluate the safety and efficacy of implantation of subcutaneous implantable cardioverter defibrillator(S-ICD)after transvenous lead extraction(TLE)in ICD patients without pacing indications.Methods:All patients who underwent TLE at Peking University People's Hospital from June 2018 to October 2023 were consecutively included.TLE indication,S-ICD implantation indication,defibrillation threshold(DFT)test,complications and postoperative follow-up were collected and analyzed.Results:A total of 11 patients with TV-ICD underwent S-ICD implantation after TLE,eight patients were males and median age were 56(44,65)years.The indications for TLE were infection and lead dysfunction.Nine patients were implanted with S-ICD for secondary prevention,and the most common cause of implantation was ion channelopathies(5 cases).The operative time for S-ICD was 51(48,58)minutes and no perioperative complications were noted.Eight patients underwent DFT testing,and 100%were successful.During a median follow up of 30(9,39)months,a total of six appropriate treatments occurred in two patients,and no complications occurred,including inappropriate treatment,ineffective treatment,infection,lead malfunction and death.Conclusions:Our study provides evidence for S-ICD implantation as a replacement after TV-ICD removal.The S-ICD implantation after TLE is safe and effective.
