OBJECTIVES: To determine whether or not surgical ablation is clinically superior to catheter ablation as the first-line treatment strategy in long-standing persistent atrial fibrillation. DESIGN: This was a prospective, multicentre, randomised control trial. SETTING: Four NHS tertiary centres in England. PARTICIPANTS: Adults with long-standing persistent atrial fibrillation, who had European Heart Rhythm Association symptom scores > 2 and who were naive to previous catheter ablation or thoracic/cardiac surgery. INTERVENTIONS: Minimally invasive thoracoscopic surgical ablation and conventional catheter ablation (control intervention). MAIN OUTCOME MEASURES: The primary outcome was freedom from atrial fibrillation/tachycardia >/= 30 seconds after a single procedure without antiarrhythmic drugs (class 1C/3) at 1 year, excluding a 3-month blanking period. The secondary outcomes include the intervention-related major complication rate; clinical success (>/= 75% reduction in arrhythmia burden); and changes in symptoms, quality of life and cost-effectiveness. METHODS: Patients (n = 120) were randomised to surgical ablation (n = 60) or catheter ablation (n = 60). An implanted loop recorder provided continuous cardiac monitoring following ablation. Follow-up visits were at 3, 6, 9 and 12 months. Loop recorder data were reviewed monthly by a physiologist who was blinded to the randomisation outcome. RESULTS: The study treatment was received by 55 patients in the surgical ablation arm and 60 patients in the catheter ablation arm; five patients withdrew from surgical ablation before treatment. Data from randomised and treated patients were analysed as per intention to treat. Patients had a mean age of 62.3 (standard deviation 9.6) years, were predominantly male (74%), had a mean left atrial diameter of 44.6 mm (standard deviation 6 mm) and were in continuous atrial fibrillation for 22 months (range 16-31 months). At 12 months, 26% of patients in the surgical ablation arm (14/54) and 28% of patients in the catheter ablation arm (17/60) were free from atrial arrhythmias after a single procedure without antiarrhythmic drugs (odds ratio 1.13, 95% confidence interval 0.46 to 2.83; p = 0.84). An arrhythmia burden reduction of >/= 75% was seen in 36 out of 54 (67%) patients in the surgical ablation arm, compared with 46 out of 60 (77%) patients in the catheter ablation arm (odds ratio 1.64, 95% confidence interval 0.67 to 4.08; p = 0.3). Procedure-related serious complications within 30 days of the intervention occurred in 15% (8/55) of patients in the surgical ablation arm (including one death) compared with 10% (6/60) of patients in the catheter ablation arm (p = 0.46). Surgical ablation was associated with significantly higher costs ( pound23,221 vs. pound18,186; p = 0.02) and fewer quality-adjusted life-years than catheter ablation (0.76 vs. 0.83; p = 0.02). LIMITATIONS: This study was conducted in four highly specialised cardiology centres that have substantial experience in both treatment modalities; therefore, the results may not be widely generalisable. The study was not powered to detect small differences in efficacy. CONCLUSIONS: We found no evidence to suggest that standalone thoracoscopic surgical ablation outcomes were superior to catheter ablation outcomes in achieving freedom from atrial arrhythmia after a single procedure without antiarrhythmic drugs. Moreover, surgical ablation is associated with a longer hospital stay, smaller improvements in quality of life and higher health-care costs than catheter ablation (standard care therapy). FUTURE WORK: Evaluation of the impact of ablation treatments on sinus rhythm maintenance and quality of life with extended follow-up to 3 years. Model-based economic analysis to estimate long-term benefits, harms and costs of surgical and catheter ablation compared with antiarrhythmic drug therapy in long-standing persistent atrial fibrillation patients.
