- AIM: The aim of this prospective substudy was to estimate the cost-effectiveness of treating paroxysmal atrial fibrillation (AF) with radiofrequency catheter ablation (RFA) compared with antiarrhythmic drugs (AADs) as first-line treatment.METHODS AND RESULTS: A decision-analytic Markov model, based on MANTRA-PAF (Medical Antiarrhythmic Treatment or Radiofrequency Ablation in Paroxysmal Atrial Fibrillation) study data, was developed to study long-term effects and costs of RFA compared with AADs as first-line treatment. Positive clinical effects were found in the overall population, a gain of an average 0.06 quality-adjusted life years (QALYs) to an incremental cost of €3033, resulting in an incremental cost-effectiveness ratio of €50 570/QALY. However, the result of the subgroup analyses showed that RFA was less costly and more effective in younger patients. This implied an incremental cost-effectiveness ratio of €3434/QALY in ≤50-year-old patients respectively €108 937/QALY in >50-year-old patients.CONCLUSION: Radiofrequency catheter ablation as first-line treatment is a cost-effective strategy for younger patients with paroxysmal AF. However, the cost-effectiveness of using RFA as first-line therapy in older patients is uncertain, and in most of these AADs should be attempted before RFA (MANTRA-PAF ClinicalTrials.gov number; NCT00133211).

- Background: The Medical ANtiarrhythmic Treatment or Radiofrequency Ablation in Paroxysmal Atrial Fibrillation (MANTRA-PAF) is a randomized trial comparing radiofrequency catheter ablation (RFA) to antiarrhythmic drugs (AADs) as first-line treatment of paroxysmal atrial fibrillation (PAF). In order to eliminate the clouding effect of crossover we performed an on-treatment analysis of the data. Methods and results: Patients (n = 294) were divided into three groups: those receiving only the assigned therapy (RFA and AAD groups) and those receiving both therapies (crossover group). The primary end points were AF burden in 7-day Holter recordings at 3, 6, 12, 18, and 24 months and cumulative AF burden in all recordings. At 24 months, AF burden was significantly lower in the RFA (n = 110) than in the AAD (n = 92) and the crossover (n = 84) groups (90th percentile 1% vs. 10% vs. 16%, P = 0.007), and more patients were free from any AF (89% vs. 73% vs. 74%, P = 0.006). In the RFA, AAD and the crossover groups 63%, 59% and 21% (P less than 0.001) of the patients had no AF episodes in any Holter recording, respectively. Quality of life improved significantly in all groups. There were no differences in serious adverse events between the RFA, AAD and crossover groups (19% vs. 8% vs. 23%) (P = 0.10). Conclusions: In the treatment of antiarrhythmic therapy naive patients with PAF long-term efficacy of RFA was superior to AAD therapy. Thus, it is reasonable to offer RFA as first-line treatment for highly symptomatic patients who accept the risks of the procedure and are aware of frequent need for reablation(s).
