A seventy year‐old male was referred to our hospital to undergo radiofrequency catheter ablation (RFCA) for drug‐refractory paroxysmal atrial fibrillation (AF). Pre‐operative three‐dimensional computed tomography revealed a unique left atrial (LA) roof vein. Electrophysiological findings showed expansion of the myocardial sleeve and local firing in the LA roof vein. We performed isolation of this arrhythmogenic abnormal vein concomitant with general pulmonary vein isolation in this case, and AF did not recur after the procedure.
