Cardioneuroablation: Three different approaches

Area of Science:

• Cardiology
• Electrophysiology
• Neurology

Background:

• Vasovagal syncope with cardioinhibitory responses presents a clinical challenge.
• Cardioneuroablation (CNA) targets autonomic neuromyocardial connections.
• Current CNA approaches vary across specialized centers.

Purpose of the Study:

• To review and compare three distinct Cardioneuroablation techniques.
• To elucidate the rationale and procedural details of each approach.
• To provide a comprehensive overview for centers performing CNA.

Main Methods:

• Review of extra-cardiac vagal stimulation-controlled CNA.
• Analysis of fractionated electrogram-guided CNA.
• Description of anatomical approach-based CNA.

Main Results:

• Detailed procedural steps for each of the three CNA techniques are presented.
• The review highlights the heterogeneity in current CNA methodologies.
• Underlying principles and target regions for each technique are discussed.

Conclusions:

• Cardioneuroablation is an evolving therapy for specific syncope types.
• Understanding different CNA techniques is crucial for procedural standardization.
• Further research may refine CNA approaches for optimal efficacy.
