Atrial fibrillation is frequently associated with typical atrial flutter in clinical practice. If the radical treatment of atrial flutter by radiofrequency catheter is achieved in most cases without recurrence, it does not prevent the occurrence of atrial fibrillation that occurs in about 70% of these patients after several years of follow-up. However, the latter arrhythmia is associated with significant morbidity and mortality. The problem of atrial fibrillation occurrence after successful ablation of typical atrial flutter remains physicians primary concern in monitoring these patients.
