Why the study?
Complications still occur with AF ablation, but limited data exist regarding the role of a repeat procedure as a predictor of complications.
Does a repeat atrial fibrillation ablation procedure increase the risk of complications compared to a first-time procedure?
Population
1243 consecutive AF ablation procedures
Comparison
Repeat AF ablation procedures vs first-time procedures
Design

Repeat AF ablation independently predicts complications; supports risk stratification but leaves open need for randomized confirmation.
Does a repeat atrial fibrillation ablation procedure increase the risk of complications compared to a first-time procedure?
A previous atrial fibrillation ablation procedure is a strong independent predictor of complications during subsequent ablation procedures.
