Cardioneuroablation for recurrent vasovagal syncope: Important questions need to be answered

Abstract

Vasovagal reflex syncope (VVS) is the most common cause of transient loss of consciousness in any setting and at all ages. Although the reflex is benign and occurs in otherwise healthy persons, the morbidity and injuries resulting from VVS can be major. In patients with frequent and burdensome cardioinhibitory VVS, cardiac pacemakers have been implanted. Cardiac pacing does seem to be beneficial for some patients, but patient selection and types of pacemakers are debated.1,2 More recently, cardioneuroablation (CNA) procedures have emerged as a novel therapy for VVS, and positive results in small open-label cohort studies have been reported.
