Comparison of the effectiveness and safety of dronedarone and amiodarone for preventing recurrence after catheter ablation of atrial fibrillation: an open-label randomized controlled trial
Authors' conclusion
Therapy with dronedarone during the blanking period after AF ablation was associated with a similar recurrence rate but a superior safety profile compared to amiodarone.
