Results from a multicentre comparison of cryoballoon vs. radiofrequency ablation for paroxysmal atrial fibrillation: is cryoablation more reproducible?

Abstract

Cryoballoon seems to be less operator-dependent and more reproducible than RF in the setting of paroxysmal AF ablation.

Sex‐specific efficacy and safety of cryoballoon versus radiofrequency ablation for atrial fibrillation: A systematic review and meta‐analysis

“…50 full‐text publications were reviewed, of which 27 were excluded: 19 based on the same cohorts, 6 focused on one type of complication and 2 with data not allowing extraction (Figure S1). 23 studies were finally included in the present systematic review and meta‐analysis …”

Pulmonary vein isolation using multi-electrode radiofrequency vs conventional point-by-point radiofrequency ablation: A meta-analysis of randomized and non-randomized studies

“…Therefore, circumferential ablation for complete electrical isolation of pulmonary veins is the cornerstone and, PVI only seems enough if persistent AF is present [31], [32]. It has been shown that PVI using cryoballoon is effective as point-by-point radiofrequency ablation with better procedural time and less operator dependence [33], [34], [35]. Encouraging novel balloon application using laser energy had also comparable outcome of freedom from arrhythmia recurrence [36], [37].…”

Impact of pulmonary vein ostia anatomy on efficacy of cryoballoon ablation for atrial fibrillation

“…It has been shown that the efficacy of this technique is similar to the standard RF-based AF ablation and may be associated with lower hospital readmissions, direct electrical cardioversions and repeated ablations [1,7] . Also the learning curve is much shorter than in the case of RF ablation, which gives a promise for more widespread use of this technique than difficult pointby-point RF ablation [8,9] . Cryoballoon-based AF ablation is a technique which is highly dependent on PV anatomy.…”
