Why the study?
Whether a left common pulmonary vein influences outcomes of repeated radiofrequency catheter ablation for recurrent atrial fibrillation had not been elucidated.
Does the presence of a left common pulmonary vein predict better outcomes after repeated radiofrequency catheter ablation in patients with recurrent atrial fibrillation?
Does the presence of a left common pulmonary vein predict better outcomes after repeated radiofrequency catheter ablation in patients with recurrent atrial fibrillation?
The presence of a left common pulmonary vein is independently associated with a lower risk of arrhythmia recurrence after repeated radiofrequency catheter ablation for atrial fibrillation.

LCPV was associated with better repeat RFCA outcomes; leaves open whether anatomy should guide ablation strategy in AF.
