Abstract:
We administered cryoballoon ablation to a 61-year-old female patient for recurrent paroxysmal atrial fibrillation. Contrast-enhanced CT angiography used to assess the patient's pulmonary vein anatomy prior to cryoballoon ablation revealed an accessory pulmonary vein emanating from the left atrial roof. Cryoballoon ablation was successfully performed on this accessory vein, which is rarely seen in the literature for the first time.
