Typical atrial flutter is a common reentrant atrial arrhythmia. The critical portion of the reentrant circuit is the rim of tissue between the tricuspid valve (TV) annulus and the inferior vena cava (IVC) (Fig.1).1,2 The reentrant circuit can operate in either clockwise or counterclockwise directions (Figs. 2–3). Elimination of conduction across the TV-IVC isthmus eliminates the tachycardia.3 The endpoint of ablation is to achieve bidirectional TVIVC isthmus block. Successful ablation of TV-IVC
