Title: Isolated Atrial Fibrillation Ablation in Patients With Isolated Atrial Flutter
Brief Summary: Ablation of the cavotricuspid isthmus (CTI) in the right atrium is currently the therapy of choice for the treatment of typical atrial flutter (3,4). It is a curative approach and has a high success rate (5). It has been recognized that patients with typical atrial flutter often complain of atrial fibrillation (1,2). Current clinical and experimental studies confirm the close relationship between atrial flutter (AFL) and atrial fibrillation (AF) and raise a question, if both arrhythmias are different forms of a common electrical phenomenon with atrial fibrillation being the underlying clinical problem (6).
