Randomized Controlled Trial Comparative Study
Recurrence of paroxysmal atrial fibrillation after pulmonary vein isolation: is repeat pulmonary vein isolation enough? A prospective, randomized trial.
In patients with paroxysmal atrial fibrillation (pAF), pulmonary vein isolation (PVI) has become an accepted treatment option with single procedure success rates of 60-80%. A repeat ablation is performed in ∼30% of patients because of arrhythmia recurrence. The strategy for this repeat procedure is not defined. ⋯ In this prospective randomized trial, patients with a recurrence of paroxysmal AF had no better outcome after repeat PVI + one left atrial line compared with patients with repeat PVI only.
