NEJM - Ablation for Persistent A Fib

"Approaches to Catheter Ablation for Persistent Atrial Fibrillation"

"CONCLUSIONS

Among patients with persistent atrial fibrillation, we found no reduction in the rate of recurrent atrial fibrillation when either linear ablation or ablation of complex fractionated electrograms was performed in addition to pulmonary-vein isolation. (Funded by St. Jude Medical; ClinicalTrials.gov number, NCT01203748.)"
