Key result
Catheter ablation of cavotricuspid isthmus-dependent atrial flutter achieved an overall acute success rate of 91.1% (95% CI, 89.5-92.4), with a 33.6% occurrence rate of subsequent atrial fibrillation.
Why the study?
What are the long-term clinical outcomes, including success, recurrence, and incident atrial fibrillation, after catheter ablation of cavotricuspid isthmus-dependent atrial flutter?

What are the long-term clinical outcomes, including success, recurrence, and incident atrial fibrillation, after catheter ablation of cavotricuspid isthmus-dependent atrial flutter?
Catheter ablation for cavotricuspid isthmus-dependent atrial flutter is highly successful and safe, though post-ablation atrial fibrillation remains common, occurring in roughly one-third of patients.
No takes yet. Share an insight, caveat, or question.
AFL ablation is safe and effective with optimal technology/endpoints; confirms substantial postablation AF risk warranting surveillance.
Pérez et al. (2009) conducted a meta-analysis in Cavotricuspid isthmus-dependent atrial flutter (n=10,719). Catheter ablation was evaluated on Overall acute success rate adjusted for reporting bias (95% CI 89.5 to 92.4). Catheter ablation of cavotricuspid isthmus-dependent atrial flutter achieved an overall acute success rate of 91.1% (95% CI, 89.5-92.4), with a 33.6% occurrence rate of subsequent atrial fibrillation.
