Several reports have described the successful insertion of implantable cardioverter defibrillator (ICD) in patients with a persistent left superior vena cava (PLSVC). The implanters have used various techniques to achieve appropriate lead placement. In our case, the use of a long sheath, guided by a deflectable catheter, not only facilitated proper implantation of the lead, but also provided a unique position of the dual-coil lead. This resulted in a very low defibrillation threshold (DFT). We describe a case of a patient found to have a PLSVC at implant who after successful insertion of the ICD exhibited DFT ≤ 5 J.
几份报告描述了在患有持续左上腔静脉（PLSVC）的患者中成功植入植入式心律转复除颤器（ICD）的情况。植入者使用了各种技术来实现导线的适当放置。在我们的病例中，在可弯曲导管引导下使用长鞘，不仅便于导线的正确植入，还使双线圈导线处于独特位置。这导致了非常低的除颤阈值（DFT）。我们描述了一例患者，在植入时发现有PLSVC，成功植入ICD后DFT≤5 J。
