Cardioneuroablation for children with syncope

PURPOSE OF REVIEW: Children with recurrent syncope with prolonged pauses who have failed traditional therapies may be candidates for a cardioneuroablation as an alternative to pacemaker implantation. This article reviews cardioneuroablation in the pediatric population. RECENT FINDINGS: Cardioneuroablation has been used in adults for cardioinhibitory syncope for more than 2 decades with promising results. Despite the heterogenous patient population and variation in technical approaches to the procedure, between 85 and 90% of patients have a significant reduction in syncope and improvement in quality of life. While the data in children is limited, reports have shown similar success. Catheter ablation of ganglionated plexuses can be performed by ablating in the right or left atrium or both. The long-term effects in disrupting the sympathovagal imbalance remains unknown. SUMMARY: Cardioneuroablation may be an option for select children with cardioinhibitory syncope who have failed standard medical approaches. Early results of vagal ablation in children have been promising. Future long-term registries following cardioneuroablation is needed.
