Outcomes of transvenous lead extraction (TLE) are well reported in the general population, However, data on safety, efficacy of TLE in octogenarians with a long lead dwell time, using powered extraction tools are limited. The aim of this multicenter study was to evaluate the safety, effectiveness of TLE in octogenarians using the bidirectional rotational mechanical sheaths and mid-term outcome after TLE.
The study population comprised 83 patients (78.3% male; mean age 85 ± 3 years; [range 80-94 years]) with 181 target leads. All the leads (mean implant duration 112 ± 77 months [range 12-377]) were extracted exclusively using the Evolution RL sheaths (Cook Medical, Bloomington, IN, USA).
The main indication for TLE was infection in 84.3% of cases. Complete procedural success rate, clinical success rate, per lead were 93.9% and 98.3%, respectively. Failure of lead extraction was seen in 1.7% of leads. The additional use of a snare was required in 8.4% of patients. Major complications occurred in one patient (1.2%). Thirty-day mortality after TLE was 6%. During a mean time follow-up of 22 ± 21 months, 24 patients (29%) died. No procedure-related mortality occurred. Predictors of mortality included ischemic cardiomyopathy (HR 4.35; 95% CI 1.87-10.13; p = .001), left ventricularejection fraction ≤35% (HR 7.89; 95% CI 3.20-19.48; p < .001), and TLE for systemic infection (HR 4.24; 95% CI 1.69-10.66; p = .002).
At experienced centers bidirectional rotational mechanical sheaths combined with different mechanical tools and femoral approach allowreasonable success and safety in octogenarian with long lead dwell time. Patient's age should not influence the decision to extract or not the leads, although the 30-day and mid-term mortality are significant, especially in the present of specific comorbidities.
经静脉导线拔除术(TLE)的结果在普通人群中已有很好的报道,然而,关于使用电动提取工具对高龄患者(留置时间长)进行 TLE 的安全性和有效性的数据有限。本多中心研究的目的是评估高龄患者(使用双向旋转机械护套)行 TLE 的安全性和有效性,并评估 TLE 后的中期结果。
研究人群包括 83 例患者(78.3%为男性;平均年龄 85 ± 3 岁[范围 80-94 岁])和 181 个靶标导联。所有导联(平均植入时间 112 ± 77 个月[范围 12-377])均仅使用 Evolution RL 护套(美国库克医疗,布卢明顿,IN)进行提取。
TLE 的主要适应证为感染,占 84.3%。完全手术成功率、临床成功率、每根导联的成功率分别为 93.9%和 98.3%。1.7%的导联出现了提取失败。8.4%的患者需要额外使用圈套器。1 例(1.2%)患者发生严重并发症。TLE 后 30 天死亡率为 6%。在平均 22 ± 21 个月的随访期间,24 例患者(29%)死亡。无与手术相关的死亡。死亡的预测因素包括缺血性心肌病(HR 4.35;95%CI 1.87-10.13;p =.001)、左心室射血分数≤35%(HR 7.89;95%CI 3.20-19.48;p <.001)和 TLE 用于全身感染(HR 4.24;95%CI 1.69-10.66;p =.002)。
在经验丰富的中心,双向旋转机械护套结合不同的机械工具和股动脉入路可使高龄患者(留置时间长)获得较高的成功率和安全性。患者年龄不应影响是否拔除导联的决定,尽管 30 天和中期死亡率较高,但存在特定合并症时尤其如此。
