Abstract
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.
期刊介绍:
The Journal of Interventional Cardiac Electrophysiology is an international publication devoted to fostering research in and development of interventional techniques and therapies for the management of cardiac arrhythmias. It is designed primarily to present original research studies and scholarly scientific reviews of basic and applied science and clinical research in this field. The Journal will adopt a multidisciplinary approach to link physical, experimental, and clinical sciences as applied to the development of and practice in interventional electrophysiology. The Journal will examine techniques ranging from molecular, chemical and pharmacologic therapies to device and ablation technology. Accordingly, original research in clinical, epidemiologic and basic science arenas will be considered for publication. Applied engineering or physical science studies pertaining to interventional electrophysiology will be encouraged. The Journal is committed to providing comprehensive and detailed treatment of major interventional therapies and innovative techniques in a structured and clinically relevant manner. It is directed at clinical practitioners and investigators in the rapidly growing field of interventional electrophysiology. The editorial staff and board reflect this bias and include noted international experts in this area with a wealth of expertise in basic and clinical investigation. Peer review of all submissions, conflict of interest guidelines and periodic editorial board review of all Journal policies have been established.
