Ablation better than amiodarone for persistent AF with congestive heart failure

AATAC Multicenter Randomized Trial [1] has demonstrated that catheter ablation is clearly superior to amiodarone for heart failure and persistent atrial fibrillation having an implanted device. The study involved about two hundred patients with dual chamber defibrillator or cardiac resynchronization therapy and left ventricular ejection fraction less than 40% with functional class of New York Heart Association II or III. The primary endpoint was recurrence of atrial fibrillation while secondary endpoints were all cause mortality and unplanned hospitalization. All the endpoints were better in the catheter ablation group compared to amiodarone group. Reference 1. Di Biase L et al.
