Carotid sinus syndrome treated by cardioneuroablation: Is sinus node denervation enough? Insights from a syncope recurrence report

Abstract

Cardioneuroablation (CNA) has been proposed as an alternative treatment for patients with refractory vasovagal syncope (VVS), functional atrioventricular block (AVB) or functional bradyarrhythmia instead of classical treatment or pacemaker (PM) (1). Vagal denervation is achieved by endocardial catheter ablation targeting atrial fibrillation nests (AFN) (2) and ganglionic plexus (GP)-related areas. We describe a clinical case of cardioinhibitory carotid sinus syndrome (CSS) treated with CNA, where partial vagal denervation was achieved over sinus node (SN).
