Isolated persistent left superior vena cava (PLSVC) provides limited access during transvenous pacemaker implantation. We present a case of implantation of a leadless pacemaker for atrioventricular block with isolated PLSVC. A leadless pacemaker is an alternative strategy to a transvenous pacemaker; however, some technical tips are required: (1) the prevention of the mis-insertion in the dilated coronary sinus and (2) the pre-assessment of the anatomy of the right atrium and ventricle.
孤立性永存左上腔静脉（PLSVC）在经静脉起搏器植入过程中提供的通路有限。我们报告一例因孤立性PLSVC伴房室传导阻滞植入无导线起搏器的病例。无导线起搏器是经静脉起搏器的一种替代策略；然而，需要一些技术要点：（1）防止误插入扩张的冠状静脉窦，以及（2）对右心房和右心室的解剖结构进行术前评估。
