Radiofrequency and cryoballon ablation have been shown to be comparable to each other in terms of safety and effectivity in patients with atrial fibrillation. However, elderly patients have been underrepresented in the previous studies. The number of older patients with atrial fibrillation is high and the number of who undergo an ablation procedure for atrial fibrillation increases steadily. This prospective randomized trial compares the effectivity (recurrency of atrial arrhythmias) and periprocedural characteristics of the two established ablation methods in patients who are 75 years or older.
