Cryoablation versus Radiofrequency Ablation in the treatment of Atrial Flutter Trial (CRAAFT)

Introduction Atrial flutter is frequently treated with radiofrequency (RF) ablation with excellent results. While RF ablation remains the gold standard for catheter based treatment of atrial flutter, cryoablation has potential advantages including painless ablation and cryoadherence to the myocardium. We performed a prospective randomised trial comparing cryoablation and RF ablation in the treatment of atrial flutter.
