Persistent left superior vena cava (SVC) is an uncommon condition, usually encountered during cannulation of the left subclavian vein. We describe a patient who required a cardiac device upgrade to cardiac resynchronization implantable cardioverter defibrillator for biventricular failure. The presence of a persistent left SVC proved to be a blessing in disguise in this patient as he had since developed total occlusion of the left subclavian-innominate system.
永存左上腔静脉（SVC）是一种罕见的情况，通常在左锁骨下静脉插管时遇到。我们描述了一名因双心室衰竭需要将心脏装置升级为心脏再同步植入式心律转复除颤器的患者。在该患者中，永存左上腔静脉的存在结果反倒成了一件幸事，因为他后来出现了左锁骨下静脉-无名静脉系统的完全闭塞。
