Persistent left superior vena cava (LPSVC) is a rare congenital anomaly of the thoracic venous system that can trigger paroxysmal atrial fibrillation. The role of this venous anomaly must be carefully considered in patients undergoing conventional atrial fibrillation transcatheter ablation by pulmonary vein isolation to avoid unnecessary lesions, left atrium access and arrhythmia relapses. In fact, the present clinical perspective suggests sole LPSVC isolation is a well tolerated and effective approach in patients with paroxysmal atrial fibrillation and arrhythmic trigger originating from a LPSVC.
永存左上腔静脉（LPSVC）是一种罕见的胸段静脉系统先天性异常，可引发阵发性心房颤动。在接受经肺静脉隔离进行传统心房颤动导管消融的患者中，必须仔细考虑这种静脉异常的作用，以避免不必要的损伤、左心房穿刺及心律失常复发。事实上，目前的临床观点表明，对于起源于LPSVC的阵发性心房颤动和心律失常触发灶患者，单纯隔离LPSVC是一种耐受性良好且有效的方法。
