BACKGROUND
After the reports of recalled leads, several technological improvements have been introduced and the durability of implantable cardioverter defibrillator (ICD) leads has improved. The incidence of lead failures is now less than in the previous studies. However, there are few reports that have shown the long-term durability of ICD leads as compared to pacemaker (PM) leads. This study analyzed the medium to long-term performance of transvenous ICD leads as compared to PM leads.
METHODS
We retrospectively studied 1227 cases from April 2007 to December 2017 who underwent an initial transvenous ICD or PM implantation. The number of lead failures and patient background characteristics were analyzed.
RESULTS
During a median 3-3.5 years follow up period, 1 (0.3%) ICD lead and 18 (2.4%) PM leads failed. The incidence of lead failures was significantly higher in the PM group than ICD group (p = .019). Males were associated with a higher incidence of lead failures in the PM group.
CONCLUSION
Since the era of recalled ICD leads, the durability of ICD leads has remarkably improved and the incidence of lead failures with non-recalled ICD leads has been less than that for PM leads.
背景
在召回事件发生后，许多技术得到了改进，植入式心脏复律除颤器（ICD）导线的耐用性也得到了提高。现在，导线故障的发生率低于之前的研究。然而，与起搏器（PM）导线相比，很少有报道显示 ICD 导线的长期耐用性。本研究分析了与 PM 导线相比，经静脉 ICD 导线的中至长期性能。
方法
我们回顾性研究了 2007 年 4 月至 2017 年 12 月期间接受初次经静脉 ICD 或 PM 植入的 1227 例患者。分析了导线故障的数量和患者的背景特征。
结果
在中位 3-3.5 年的随访期间，1 例（0.3%）ICD 导线和 18 例（2.4%）PM 导线发生故障。PM 组的导线故障发生率明显高于 ICD 组（p=0.019）。男性在 PM 组中与导线故障的发生率较高相关。
结论
自召回 ICD 导线时代以来，ICD 导线的耐用性显著提高，非召回 ICD 导线的故障发生率低于 PM 导线。
