A 46-year-old man presented to our institution with inappropriate implantable cardioverter-defibrillator (ICD) shock delivery. The ICD (single chamber, dual shock coils) was implanted for sustained monomorphic ventricular tachycardia with unstable hemodynamics and underlying systolic left ventricular dysfunction. ICD interrogation revealed recurrent episodes of ICD shock due to noise sensing and increased impedance of right ventricular (RV)-lead. With the impression of lead fracture, ICD lead extraction was performed. The fractured ICD lead was completely removed by traction of locking stylet and counter-traction of polypropylene dilator sheath. A new lead was inserted and the patient was discharged without complications after 2 days. To our knowledge, this is the first report on ICD lead extraction by conventional traction and counter-traction technique in Korea.
一位 46 岁男性因不适当的植入式心律转复除颤器（ICD）电击而到我院就诊。该患者因持续性单形性室性心动过速、血流动力学不稳定和固有左心室收缩功能障碍而植入 ICD（单腔、双电击线圈）。ICD 检测显示因噪声感应和右心室（RV）导联阻抗增加而反复发生 ICD 电击。考虑为导联断裂，行 ICD 导联取出术。通过牵引锁定导丝和反牵引聚丙烯扩张鞘，完全取出断裂的 ICD 导联。插入新的导联后，患者在 2 天后无并发症出院。据我们所知，这是韩国首例通过传统牵引和反牵引技术进行 ICD 导联取出的报告。
