Аннотация
BACKGROUND: Cardioneuroablation (CNA) is an emerging treatment for cardioinhibitory syncope and functional AV block. This study aimed to evaluate the safety and efficacy of a fluoroless CNA approach using three-dimensional mapping and extracardiac vagal stimulation (ECVS).
METHODS: This prospective observational study included 22 patients (mean age 21 years) with clinically significant functional bradycardia who underwent fluoroless CNA. Procedural success was defined as elimination or significant attenuation of the vagal response to ECVS.
RESULTS: CNA was successfully performed in all patients with a mean procedure time of 251 min. Fluoroscopy was avoided in 91% of cases. At a mean follow-up of 11.4 months, 77% of patients remained symptom-free. Among pacemaker patients, 90% did not require further pacing, and 6/10 (60%) have had their pacemakers turned off. No complications were seen during the procedure.
CONCLUSIONS: Fluoroscopy-free CNA is a safe and effective treatment for functional bradycardia, offering high procedural success rates and favorable symptom-free outcomes while minimizing radiation exposure.
