Key result
Cryoablation using triple freeze-thaw cycles for AVNRT in children achieved a 96.2% acute success rate and a 1.96% recurrence rate over a mean follow-up of 30.7 months.

Does triple freeze-thaw cycle cryoablation prevent recurrence of supraventricular tachycardia in pediatric patients with AVNRT?
Triple freeze-thaw cycle cryoablation provides a high acute success rate and low long-term recurrence rate for treating AVNRT in pediatric patients.
Qureshi et al. (2012) conducted an observational in Atrioventricular nodal reentrant tachycardia (AVNRT) (n=53). Cryoablation was evaluated on Recurrence of supraventricular tachycardia. Cryoablation using triple freeze-thaw cycles for AVNRT in children achieved a 96.2% acute success rate and a 1.96% recurrence rate over a mean follow-up of 30.7 months.
