The laboratory evaluation and role of catheter ablation for patients with atrial flutter.
The anatomic substrate for atrial flutter has now been recognized, and improved methods for catheter ablation have been developed. Using mapping techniques such as entrainment mapping, recognizing the different types of flutter that can occur, and testing for conduction block with pacing after ablation, long-term cure of atrial flutter can be achieved in most patients with catheter ablation. Not only is catheter ablative cure of atrial flutter the treatment of choice for drug-refractory patients, but also may now be offered as an alternative to drug therapy.
