Cryoballoon (CB) has emerged as a reasonable alternative to radiofrequency for treatment of paroxysmal atrial fibrillation (AF) due to simple operation, short learning curve, less patient discomfort, shorter ablation time, etc., However, the second-generation CB had a higher probability than the first-generation CB in the phrenic nerve injury (PNI) mostly observed in freezing the right superior pulmonary vein. Few reports on the CB ablation for a refractory AF originating from superior vena cava.what's more,It is rare to publish Phrenic Nerve Injury(PNI) is occurred in CB ablation for AF from SVC,the case is about it.
