Key result
Cardioneuroablation reduced the median longest pause from 8.9s pre-procedure to 1.1s at 6 months, with no recurrent syncope in pediatric patients with functional AV block or sinus pauses.
Why the study?
Severe transitory bradycardia with syncope in children can rarely involve prolonged asystolic episodes, motivating description of the methodology and role of cardioneuroablation for functional atrioventricular block or sinus pauses.
Does cardioneuroablation reduce pause duration and prevent syncope in pediatric patients with functional sinus node dysfunction and paroxysmal AV block?
Population

Does cardioneuroablation reduce pause duration and prevent syncope in pediatric patients with functional sinus node dysfunction and paroxysmal AV block?
Cardioneuroablation effectively reduced sinus pauses and prevented syncope in a small cohort of pediatric patients, suggesting it may be a viable alternative to pacemaker implantation.
Choi et al. (2023) conducted an observational in functional sinus node dysfunction and paroxysmal atrioventricular block (n=6). Cardioneuroablation was evaluated on longest pause and syncope. Cardioneuroablation reduced the median longest pause from 8.9s pre-procedure to 1.1s at 6 months, with no recurrent syncope in pediatric patients with functional AV block or sinus pauses.
