摘要：

Background: Circumferential pulmonary vein ablation is still the standard approach in patients with persistent atrial fibrillation. However, the results are not very favourable and more complex ablation strategies are the subject of current controversy. Therefore, we have evaluated the effect of an additional linear lesion at the roof of the left atrium on the long-term outcome. Methods: A total of 125 patients with symptomatic persistent atrial fibrillation underwent a circumferential pulmonary vein ablation procedure in combination with an additional linear lesion at the roof of the left atrium (group A). The long-term follow-up data was compared to 125 patients with similar clinical characteristics who underwent circumferential pulmonary vein ablation without an additional linear lesion at the roof of the left atrium (group B). Results: The ablation procedure could be performed as planned in all 250 patients. Three years after catheter ablation, the success rate was 72.0% (no arrhythmia recurrence in 90 out of 125 patients) in group A and 63.2% in group B (no arrhythmia recurrence in 79 out of 125 patients; P = 0.04). There were no major complications. Conclusions: Catheter ablation of persistent atrial fibrillation comprising a circumferential pulmonary vein ablation and an additional linear lesion at the roof of the left atrium provides more favourable long-term results than circumferential pulmonary vein ablation alone. © 2017, Springer Medizin Verlag GmbH.
