There have been few randomization trials directly comparing CryoBalloon ablation to RF ablation.
That’s why Dr. Armin Luik and his colleagues developed the FreezeAF clinical trial―to directly compare CryoBalloon ablation to RF ablation for treating patients with paroxysmal atrial fibrillation. Dr. Luik (U. of Freiburg, Karlsruhe, Germany) presented the study results at the May 2015 meeting of the Heart Rhythm Society.
FREEZEAF Trial: Patients and Method
In the FREEZEAF study, 315 paroxysmal A-Fib patients with a mean age of 60 years were randomized to either a CryoBalloon ablation (n=156) or a RF ablation (n=159) of the pulmonary veins. Clinical follow up was at three, six, nine and 12 months.
The FREEZEAF Study Results
The FreezeAF trial researchers noted that a number of CryoBalloon ablation studies have demonstrated its efficacy and safety for treatment of A-Fib, but few studies have compared the two techniques head-to-head.
