In some patients, rapid activation from one or several foci can lead to atrial fibrillation. This study evaluated long-term changes in quality of life and healthcare resource utilization in patients with atrial fibrillation treated by ablation of focal triggers. Thirty-three patients underwent ablation for paroxysmal atrial fibrillation. Health surveys (SF-36) were obtained at baseline, and after 1 year and 3 years of follow-up. Health care costs were measured for the 3 years before and after ablation. Ablation was successful in 82%, partially successful in 12% (no sustained episodes but on antiarrhythmic drug therapy), and unsuccessful in 6% of patients. The average number of ablation procedures was 1.6 +/- 0.6 per patient. After ablation, patients reported significantly improved quality of life in all SF-36 categories except bodily pain. Healthcare resource utilization was significantly reduced after ablation (Clinic visits: 7.4 +/- 2.5 per year vs. 1.1 +/- 0.6 per year, p < 0.05; Emergency room visits: 1.7 ± 0.90 per year vs. 0.03 ± 0.17 per year, p < 0.05; Hospitalization: 1.6 +/- 0.81 vs. 0, p < 0.05). Cost of healthcare (not including procedural costs) was significantly reduced after ablation (Pre-ablation: $1,920 ± 889/year vs. post-ablation: $87 ± 68/year; p < 0.01). Procedural cost of ablation was $17,173 +/- 2,466/patient. Ablation of focal triggers of atrial fibrillation is associated with a sustained improvement in quality of life. Although the initial cost of ablation is high, after ablation, utilization of healthcare resources is significantly reduced.
