Does cardioneuroablation prevent syncope and avoid pacemaker implantation in a patient with high-degree AV block?
Cardioneuroablation may be an effective alternative to pacemaker implantation in young patients with vagally mediated high-degree AV block.

May support cardioneuroablation to avoid pacing in select young patients with vagally mediated AV block; hypothesis-generating and requires prospective validation.
A 23-year-old-female patient had undergone a very successful gastric banding surgery to treat obesity. Six months later she began to present recurrent syncope due to very frequent, intermittent high-degree AV block referred to as pacemaker implantation. The electrophysiological study showed impaired AV nodal conduction but the His-Purkinje conduction was preserved. Partial catheter radiofrequency ablation of the cardiac autonomic nervous system guided by spectral endocardial mapping (cardioneuroablation) was performed. The electrophysiological parameters were normalized. Holter recordings were normal and the patient was asymptomatic with normal life without pacemaker implantation in a follow-up 21 months later.

M et al. (2006) conducted a case report in Syncopal High-Degree AV Block (n=1). Partial catheter radiofrequency ablation of the cardiac autonomic nervous system (cardioneuroablation) was evaluated on Normalization of electrophysiological parameters, normal Holter recordings, and remaining asymptomatic without pacemaker implantation. Cardioneuroablation successfully normalized electrophysiological parameters and prevented syncope in a 23-year-old female with high-degree AV block, avoiding pacemaker implantation over 21 months.
