Persistent left superior vena cava (PLSVC) is a rare congenital anomaly of the superior venous system that may be discovered at the time of cardiac implantable electronic device (CIED) implantation.
We present a subject who needed cardiac resynchronization therapy (CRT)-CIED implantation and was discovered to have PLSVC with absent innominate vein during the implant procedure. We were able to successfully implant a CRT-CIED using a right-sided approach via the right superior vena cava (SVC). We present a description of our implant technique and a brief review of the different aspects of CIED implantation in subjects with variants of PLSVC.
Superior venous anomalies such as PLSVC can make CIED implantation technically challenging. However, with increasing operator experience, cardiac imaging and appropriate tools successful CIED implantation is possible in almost all cases.
永存左上腔静脉（PLSVC）是一种罕见的上腔静脉系统先天性异常，可能在心脏植入式电子设备（CIED）植入时被发现。
我们报告一名需要进行心脏再同步治疗（CRT）-CIED植入的患者，在植入过程中发现其存在PLSVC且无名静脉缺如。我们通过右侧入路经右上腔静脉（SVC）成功植入了CRT-CIED。我们描述了我们的植入技术，并简要回顾了PLSVC变异患者CIED植入的不同方面。
诸如PLSVC等上腔静脉异常会使CIED植入在技术上具有挑战性。然而，随着操作者经验的增加、心脏成像技术的应用以及合适工具的使用，几乎在所有情况下都可以成功植入CIED。
