Cardioneuroablation: una revisione completa.

Cardioneuroablation (CNA) has emerged as a promising therapeutic strategy for functional bradyarrhythmias, particularly in cases of cardioinhibitory neurocardiogenic syncope and certain forms of atrial fibrillation. Indeed, by targeting vagal innervation through endocardial radiofrequency catheter ablation, CNA can obviate the need for pacemaker (PM) implantation. This technique involves denervation of specific vagal nerve structures within the atria to modulate autonomic balance and prevent symptomatic bradycardia. The efficacy of this approach stems from the recognition that an imbalance between sympathetic and parasympathetic tones, often characterized by excessive vagal activity, underpi
