Predictors of acute and long-term success after radiofrequency catheter ablation of type 1 atrial flutter

A history of atrial fibrillation and right atrial size are both determinants of procedural and long-term outcome after RF catheter ablation of type 1 atrial flutter. The results of this study suggest that patients with no history of atrial fibrillation and a normal right atrial size have the best short- and long-term results from this procedure.
