Treatment success and its predictors as well as the complications of catheter ablation for atrial fibrillation in a high-volume centre.

According to multivariable analysis, left atrial diameter and previous AAD use remained as significant and AF type as borderline significant predictors of treatment success (maintenance of normal sinus rhythm): OR 0.60 (95% CI 0.40–0.91, p = 0.016) for a 1-cm increase in left atrium diameter, OR 0.50 (0.313–0.808, p = 0.005) for previous use of AADs, and OR 1.49 (0.97–2.22, p = 0.051) for paroxysmal AF type.
