Complications related to coronary sinus lead are not infrequent in recipients of cardiac resynchronization devices. We describe the case of a patient with a biventricular implantable cardioverter defibrillator with persistent phrenic nerve stimulation, previous coronary sinus lead fracture, and severe left subclavian vein stenosis. The reimplantation of a new coronary sinus lead on the left side, ipsilateral to the original implant, was unsuccessful. In order to avoid more complex and risky procedures, we performed the repair of the fractured abandoned lead with the reconstruction of the unipolar lead terminal. Effective biventricular pacing was obtained with satisfactory electrical parameters and it was maintained at twelve months follow-up.
在心脏再同步治疗设备的接受者中，与冠状静脉窦导联相关的并发症并不罕见。我们描述了一例患有双心室植入式心脏复律除颤器的患者，该患者存在持续性膈神经刺激、既往冠状静脉窦导联断裂以及严重的左锁骨下静脉狭窄。在与原植入部位同侧的左侧重新植入一根新的冠状静脉窦导联未成功。为了避免更复杂且有风险的手术，我们对断裂的废弃导联进行了修复，并重建了单极导联末端。获得了有效的双心室起搏，电参数令人满意，且在12个月的随访中得以维持。
