Key result
Radiofrequency catheter ablation of the inferior vena cava-tricuspid annulus isthmus achieves high acute success for atrial flutter, but complete bidirectional block is needed to prevent recurrence.
Why the study?
Does catheter ablation targeting the inferior vena cava-tricuspid annulus isthmus improve acute success and prevent late recurrences in patients with common type atrial flutter?

Confirmation of bidirectional block may prevent recurrence after isthmus ablation; leaves open standardization of endpoints in prospective trials.
Saoudi et al. (1996) conducted a review in Atrial flutter. Radiofrequency catheter ablation was evaluated.
