Left ventricle (LV) lead placement in a coronary sinus branch for cardiac resynchronization therapy may fail because of anatomical variants, phrenic nerve stimulation, and/or lead instability. We report a case of successful resynchronization from a lead inserted from the left subclavian vein and positioned through a patent foramen ovale (PFO). In conclusion, endocardial LV lead insertion through a PFO enables effective resynchronization delivery without the risks associated with a thoracotomy or atrial transseptal puncture.
左心室(LV)导线在冠状窦分支中的放置可能因解剖变异、膈神经刺激和/或导线不稳定而失败。我们报告了一例从左锁骨下静脉插入的导线通过卵圆孔未闭(PFO)定位并成功实现心脏再同步治疗的病例。总之,通过 PFO 进行心内膜 LV 导线插入可以实现有效的再同步治疗,而不会带来开胸手术或经房间隔穿刺的相关风险。
