A case of pulmonary vein reconnection after long-term success of pulmonary vein isolation for atrial fibrillation.

We describe a case where right superior pulmonary vein was not reconnected at the beginning of the third radiofrequency catheter ablation (RFCA) for atrial fibrillation but was reconnected at the beginning of the fourth RFCA. This is a case of pulmonary vein reconnection in the chronic phase after successful pulmonary vein isolation.
