Key result
Cavotricuspid isthmus ablation for atrial flutter is followed by atrial fibrillation in 23% of patients, while atrial fibrillation ablation is followed by atrial flutter in 20%.
Why the study?
There is increasing evidence of an interrelationship between atrial flutter and atrial fibrillation, demonstrated by high co-occurrence and cross-development following catheter ablation.
Key points are not available for this paper at this time.
Highlights the interrelationship between atrial flutter and atrial fibrillation, noting high rates of cross-development even after ablative therapies.
There is increasing evidence of an interrelationship between atrial flutter (AFL) and atrial fibrillation (AF). This is illustrated by the large proportion of patients with AF who also have AFL, and vice versa. Even after cavotricuspid isthmus ablation (CTI) for AFL, 23% of these patients develop AF1 and after AF ablative therapy, 20% of AF patients develop AFL.2
