Prediction of arrhythmia recurrence after atrial fibrillation ablation in patients with normal anatomy of the left atrium.

Background: Enlarged left atrium is an established predictor of atrial fibrillation recurrence after pulmonary vein isolation but arrhythmia recurrence is also observed in patients with normal anatomy of the left atrium. The aim of the study is to evaluate arrhythmia recurrence predictors in patients with normal anatomy of the left atrium.

Methods: The study included 182 patients with normal anatomy of the left atrium who underwent pulmonary vein isolation using catheter ablation.
