Persistent left superior vena cava (LSVC) is a congenital anomaly with 0.3%-1% prevalence in the general population. It is usually asymptomatic but in case of transvenous lead positioning, i.e., for pacemaker or implantable cardioverter defibrillator (ICD), may be a cause for significant complications or unsuccessful implantation. Single lead ICD with atrial sensing dipole (ICD DX) is a safe and functional technology in patients without congenital abnormalities. We provide a review of the literature and a case report of successful implantation of an ICD DX in a patient with LSVC and its efficacy in treating ventricular arrhythmias.
永存左上腔静脉（LSVC）是一种先天性异常，在普通人群中的患病率为0.3%-1%。它通常无症状，但在经静脉放置导线时，即用于起搏器或植入式心脏复律除颤器（ICD）时，可能会导致严重并发症或植入失败。具有心房感知偶极的单导线ICD（ICD DX）在没有先天性异常的患者中是一种安全且有效的技术。我们对文献进行了综述，并报告了1例成功为患有LSVC的患者植入ICD DX及其治疗室性心律失常疗效的病例。
