-
Background!#!Pulmonary vein isolation is an established strategy for catheter ablation of atrial fibrillation (AF). However, in a significant number of patients, a repeat procedure is mandatory due to arrhythmia recurrence. In this study, we report safety data and procedural details of patients undergoing index ablation versus repeat ablation in a registry-based real-life setting.!##!Methods!#!Patients from the German Ablation Registry, a prospective, multicentre registry of patients undergoing ablation between January 2007 and January 2010 were included.!##!Results!#!A total of 4155 patients were enrolled in the study. Group I (index ablation) consisted of 3377/4155 (82.1%) and group II (repeat ablation) of 738/4155 (17.9%). Patients in group I had a significantly higher ratio of paroxysmal AF (69.3% vs 61.9%, p < 0.001) and significantly less persistent AF (30.7% vs 38.1%, p < 0.001). The repeat group showed significantly lower mean RF application duration (2580 s. vs 1960, p < 0.001), less fluoroscopy time (29 min. vs. 27 min., p < 0.001), less mean dose area product (DAP) (3744 cGy × cm!##!Conclusion!#!Repeat catheter ablation is safe and provides a symptomatic relief comparable to index ablation. Repeat procedures are significantly shorter and use less fluoroscopy.
