“…In our country, its feasibility, safety and efficacy have been demonstrated recently by Canale et al [6] in a heterogeneous group of patients undergoing cardiac surgery, in general, with maintenance of sinus rhythm after 1 year of 76%. Other forms of energy were studied by the authors in our country, such as unipolar radiofrequency by Breda et al [7] and Abreu Filho et al [8], showing mixed results and the use of ultrasound by Brick et al [9]. However, as far as best of our knowledge, this is the first national experience of exclusive study of patients with rheumatic mitral valve disease using a bipolar radiofrequency.…”

Objective: To analyze the effectiveness of surgical treatment of atrial fibrillation (AF) using bipolar radiofrequency ablation during mitral valve procedures of rheumatic etiology in heart surgery.Methods: We retrospectively reviewed medical registries of 53 patients submitted to atrial ablation with bipolar radiofrequency energy during mitral valve surgery. Thirty four (64%) patients were women and the age varied from 27 to 72 years old (average: 49.3 ± 10.7 years). Aortic and/or tricuspid procedures were also present in 36 (68%) patients. Average time of reported atrial fibrillation was 41 months (from 3 to 192 months). Type of AF was classified as: paroxysmal in 8 patients, persistent in 3, permanent in 42. Left atrium had an average size of 52.9 ± 8.5 mm. The surgeries in these series were: 47 mitral valve replacements and 6 mitral valve repairs. Eletrocardiografic follow up was 83% complete in 14 months. Data from 24h Holter were explored.Results: Seven (13%) perioperative deaths were observed and survival after 14 months was 87%. Observed heart rhythm after 1 year of surgery was sinus rhythm in 25 (66%) patients, AF in 7 (18%), flutter in 7 (13%), junctional in 1 (3%).Conclusion: Bipolar radiofrequency ablation in patients submitted to mitral valve surgery of rheumatic etiology is effective in converting to sinus rhythm in 68% of patients after 14 months.

“…In Brazil, Brick et al [38] published the results of 27 patients undergoing the application of ultrasound for treatment of AF and had reversion to sinus rhythm in 81.4% of cases at hospital discharge. The use of epicardial ultrasound was evaluated in patients with ischemic disease, and in at least 6 months of follow-up, we observed a success rate of 85% of patients free from tachyarrhythmias (atrial flutter or atrial fibrillation) [39].…”

When atrial fibrillation (AF) is present in pre-operative open heart surgeries, including coronary artery bypass grafting and valve operations, it represents an independent risk factor for cardiac events and reduced survival. Due to the complexity of the subject, especially when evaluating success rates (reversion and maintenance of normal sinus rhythm), a consensus statement was recently proposed by the International Society of Minimally Invasive Cardiothoracic Surgery (ISMICS), in order to determine whether the intraoperative ablation of AF promotes favorable clinical outcomes in patients undergoing other cardiac operations in comparison with individual operations without ablation. The aim of this paper is to present published data which has contributed to consensus statement and can be useful as update source. The integrative review was the methodology that provides synthesis of knowledge and applicability of results of significant studies about presented topic. Descriptors
