Key result
Radiofrequency ablation for ectopic atrial tachycardia in young patients achieved a 97% acute success rate, with a 20% recurrence rate over a median follow-up of 38 months.
Why the study?
Radiofrequency ablation is often considered the treatment of choice for ectopic atrial tachycardia in young patients, but long-term follow-up needed evaluation.
Does radiofrequency ablation safely and effectively treat ectopic atrial tachycardia in young patients?
Cohort (n=36)

Does radiofrequency ablation safely and effectively treat ectopic atrial tachycardia in young patients?
Radiofrequency ablation for ectopic atrial tachycardia in young patients is safe and highly effective acutely (97% success), though patients should be counseled on a 20% recurrence risk primarily within the first 6 months.
May support RF ablation for EAT in young patients; leaves open durability and safety in larger prospective cohorts.
AIM: Ectopic atrial tachycardia (EAT) is a common arrhythmia in children, adolescents, and young adults. Radiofrequency (RF) ablation is often considered the treatment of choice in this population. We sought to evaluate the long-term follow-up after RF ablation. METHODS AND RESULTS: We retrospectively analyzed 36 young patients (age range 8-29 years), with clinical signs and symptoms suspected for EAT who underwent an electrophysiological study in our center. We evaluated the safety and acute success rate of ablation and the long-term follow-up. Ectopic foci were more frequently localized in the right atrium along the crista terminalis (28%) and EAT was successfully terminated in 97% of patients. At median follow-up (38 months), the recurrence rate was 20% with mostly recurrences expressed within 6 months. CONCLUSIONS: The study confirmed the safety and high acute success rate of EAT ablation in a population of children, adolescents, and young adults. Therefore, catheter ablation of EAT can be considered early in the course of treatment of these patients. The evidence of most recurrences within 6 months could be useful for advising patients on likely outcomes.

Balla et al. (2019) conducted a cohort in Ectopic atrial tachycardia (n=36). Radiofrequency ablation was evaluated on Acute success rate. Radiofrequency ablation for ectopic atrial tachycardia in young patients achieved a 97% acute success rate, with a 20% recurrence rate over a median follow-up of 38 months.
