For medically refractory vasovagal syncope and functional bradycardia, the feasibility of off-label catheter cardioneuroablation was supported by multicenter U.S. registry data. The approach, consisting of electro-anatomical-guided endocardial ablation of ganglionated plexus regions in the left and/or right atria, elicited vagal responses in 52% of cases, sympathetic responses in 73%, and an average increase in heart rate of 20 bpm. The prevention of syncope was evident with 78% of people recurrence-free at a mean follow-up of 14 months. By then, 97% of the 205-person cohort were still free of pacemaker implantation, reported Roderick Tung, MD, chief of Cardiology at the University of Arizona College of Medicine – Phoenix, at the Heart Rhythm Society annual meeting.
