In treating atrial fibrillation, a transmural lesion is key to successful ablation because it keeps errant electrical signals from being transmitted. Today there are many sources being used in a.f. catheter ablations. Following several multicentric studies, now we know that a transmural lesion can be obtained using second generation cryoballoons which create a better balance between safety and efficacy.
