Atrial Fibrillation Ablation by Cryoablation


La cryoablation It is an advanced technique for the treatment of paroxysmal and persistent atrial fibrillation, in which the applied energy source is cold and not heat, as occurs in the conventional procedure.

While the approach is the same, the greatest benefit of this technique lies in the fact that the lesion in the antrum of each vein is frozen using a balloon that is placed in the vein. Thus, in a single application, and very quickly and effectively, each vein is isolated, significantly reducing the procedure time and thus its risks. Recent studies have shown that cryoablation is a highly effective technique (lower arrhythmia recurrence rate) and safe (fewer complications) compared to the traditionally used conventional radiofrequency ablation technique.
