Cryoballoon ablation provides an effective alternative strategy for treating paroxysmal and persistent atrial fibrillation, with specific techniques available to reduce procedural complications.
Does cryoballoon ablation improve outcomes in patients with paroxysmal and persistent atrial fibrillation?
This review summarizes the efficacy, safety, and practical procedural steps for cryoballoon ablation as an alternative strategy for treating paroxysmal and persistent atrial fibrillation.
Focal point-by-point radiofrequency catheter ablation has shown considerable success in the treatment of paroxysmal atrial fibrillation. However, it is not without limitations. Recent clinical and preclinical studies have demonstrated that cryothermal ablation using a balloon catheter (Artic Front©, Medtronic CryoCath LP) provides an effective alternative strategy to treating atrial fibrillation. The objective of this article is to review efficacy and safety data surrounding cryoballoon ablation for paroxysmal and persistent atrial fibrillation. In addition, a practical step-by-step approach to cryoballoon ablation is presented, while highlighting relevant literature regarding: 1) the rationale for adjunctive imaging, 2) selection of an appropriate cryoballoon size, 3) predictors of efficacy, 4) advanced trouble-shooting techniques, and 5) strategies to reduce procedural complications, such as phrenic nerve palsy.
Andrade et al. (Thu,) conducted a review in Paroxysmal and persistent atrial fibrillation. Cryoballoon ablation was evaluated. Cryoballoon ablation provides an effective alternative strategy for treating paroxysmal and persistent atrial fibrillation, with specific techniques available to reduce procedural complications.
