Original Title: Crio-ablación en la fibrilación auricular con catéter Arctic-Front
Authors' objectives: To evaluate the effectiveness and potential benefits and adverse effects of catheter cryoablation compared with other therapeutic procedures. Similarly, to find information regarding the cost of the new technique.
Authors' results and conclusions: Case series and studies reveal treatment success rates, defined as the absence of recurrent atrial fibrillation (AF), of between 45% and 89% after mean follow-up periods ranging from 6 to 19.9 months, in a total of 2149 patients. The results of comparative studies show that after a mean follow-up time of six to 12 months, treatment success ranged from 55% to 70% with «Arctic Front» cryoablation compared to 45% and 80% for radiofrequency ablation. Conclusions Cryoballoon ablation has proven to be safe and effective and preliminary data have shown comparable results to radiofrequency ablation in terms of maintenance of sinus rhythm or reduction of episodes of atrial fibrillation. The superiority of catheter ablation over medical therapy in maintaining sinus rhythm has been documented, and its effectiveness is comparable to that of radiofrequency ablation. Randomised studies comparing cryoablation with radiofrequency ablation are required, to establish more directly the impact of factors such as type of energy, experience of medical staff, underlying diseases or types of atrial fibrillation.
Authors' methods: Non-time-limited search of scientific literature in databases containing primary, secondary and applied research papers such as Medline, CRD (INAHTA, NHS EED, DARE), Cochrane Collaboration, National Guidelines Clearinghouse (NGC), EuroScan and ECRI, in order to locate systematic reviews, clinical practice guidelines and clinical trials analysing the technique in question.
