Does cavotricuspid isthmus cryoablation prevent recurrence in patients with common atrial flutter?
Cavotricuspid isthmus cryoablation is highly effective and safe for common atrial flutter, achieving a 91% long-term success rate, though atrial fibrillation frequently co-occurs or develops subsequently.
Moreira et al. (2008) conducted an observational in Common type atrial flutter (n=180). Cavotricuspid isthmus (CTI) cryoablation was evaluated on Chronic success rate (freedom from symptomatic atrial flutter recurrence). Cryoablation of the cavotricuspid isthmus in patients with common type atrial flutter achieved a 91% chronic success rate over a mean follow-up of 27 months.
