- 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).

- Aims The Medical ANtiarrhythmic Treatment or Radiofrequency Ablation in Paroxysmal Atrial Fibrillation (MANTRA-PAF) trial assessed the long-term efficacy of an initial strategy of radiofrequency ablation (RFA) vs. antiarrhythmic drug therapy (AAD) as first-line treatment for patients with PAF. In this substudy, we evaluated the effect of these treatment modalities on the Health-Related Quality of Life (HRQoL) and symptom burden of patients at 12 and 24 months. Methods and results During the study period, 294 patients were enrolled in the MANTRA-PAF trial and randomized to receive AAD (N = 148) or RFA (N = 146). Two generic questionnaires were used to assess the HRQoL [Short Form-36 (SF-36) and EuroQol-five dimensions (EQ-5D)], and the Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia (ASTA) was used to evaluate the symptoms appearing during the trial. All comparisons were made on an intention-to-treat basis. Both randomization groups showed significant improvements in assessments with both SF-36 and EQ-5D, at 24 months. Patients randomized to RFA showed significantly greater improvement in four physically related scales of the SF-36. The three most frequently reported symptoms were breathlessness during activity, pronounced tiredness, and worry/anxiety. In both groups, there was a significant reduction in ASTA symptom index and in the severity of seven of the eight symptoms over time. Conclusion Both AAD and RFA as first-line treatment resulted in substantial improvement of HRQoL and symptom burden in patients with PAF. Patients randomized to RFA showed greater improvement in physical scales (SF-36) and the EQ-visual analogue scale.

- Background: Living with paroxysmal supraventricular tachycardia affects a patient's whole life situation, but few studies have addressed health-related quality of life (HRQOL) aspects in these patients. The aim was therefore to describe HRQOL in patients with atrioventricular nodal re-entry tachycardia (AVNRT) or Wolff-Parkinson-White (WPW) syndrome, referred for radiofrequency ablation (RF-ablation), compared to age- and gender-matched Swedish reference groups. Methods: HRQOL was assessed with SF-36 and EuroQol (EQ-5D and EQ-VAS) and the patients were asked disease-specific questions. Results: The 97 patients with AVNRT [53 ± 16 years of age/65 women] and 79 patients with WPW [42 ± 15 years of age/26 women] exhibited significantly lower HRQOL scores in SF-36 in the same seven of the eight scales: Physical functioning (PF), role-physical (RP), social functioning (SF), role-emotional (RE), general health (GH), vitality (VT), and mental health (MH) while there was no difference in bodily pain (BP) compared to their respective age- and gender matched Swedish reference group. HRQOL scores were lower for patients with AVNRT compared to WPW in the areas of PF (P < 0.001), BP (P < 0.05), and GH (P < 0.01) in SF-36, and the same was found in EQ-VAS (64.8 vs. 71.2, P < 0.05). Occurrence of episodes of tachycardia more often than once a month compared to less frequently than once a month was associated with significantly lower HRQOL in all eight scales in SF-36 (GH, RE, MH: P < 0.01 and PF, RP, BP, VT, SF: P < 0.001) and EQ-5D index (P < 0.001) and EQ-VAS (P < 0.05) Arrhythmia duration longer than one hour compared to patients with shorter duration of the tachycardia-affected GH in SF-36 negatively (P < 0.05). Patients who experienced symptoms not only during activity but also at rest scored lower in SF-36 GH (P < 0.01) and SF (P < 0.05). Conclusion: Measuring HRQOL in patients with WPW or AVNRT is an important way to evaluate and describe these patients' life situation. These conditions were found to have a pronounced negative impact on HRQOL. The frequency of arrhythmia occurrence is one important factor to consider when setting priorities for treatment with RF-ablation.
