Cardioneuroablation: A Comprehensive Review.

Area of Science:

• Cardiology
• Electrophysiology
• Autonomic Nervous System Research

Background:

• Functional bradyarrhythmias, including cardioinhibitory neurocardiogenic syncope and some atrial fibrillation types, are often linked to autonomic nervous system imbalance.
• Excessive vagal activity is a key factor contributing to these arrhythmogenic conditions.
• Current treatments may involve pacemaker implantation, which addresses symptoms but not the underlying etiology.

Purpose of the Study:

• To review and synthesize current knowledge on Cardioneuroablation (CNA) techniques.
• To explore the mechanisms, clinical applications, and patient outcomes associated with CNA.
• To highlight CNA as a therapeutic strategy for functional bradyarrhythmias.

Main Methods:

• Endocardial radiofrequency catheter ablation targeting specific vagal nerve structures in the atria.
• Modulation of autonomic balance through denervation procedures.
• Review of existing literature on various CNA techniques and their efficacy.

Main Results:

• CNA demonstrates potential to obviate the need for permanent pacemaker implantation in select patients.
• The technique effectively modulates autonomic balance by targeting vagal innervation.
• Addresses the underlying etiology of bradyarrhythmias, offering a potentially more effective approach than symptom management alone.

Conclusions:

• Cardioneuroablation is a promising therapeutic strategy for functional bradyarrhythmias.
• By modulating autonomic nervous system signaling, CNA offers an alternative to pacemaker implantation.
• Further research into CNA techniques and outcomes across diverse populations is warranted.
