Cardioneuroablation for vasovagal syncope: insights on patients’ selection, centre settings, procedural workflow and endpoints—results from an European Heart Rhythm Association survey
Authors' conclusion
The results show high expectations for the future of CNA, but important heterogeneity exists regarding indications, procedural workflow, and endpoints of CNA.

Main finding
As reported in the abstract
- Performed a CNA during the last 12 months
- Half
- Systematic GP ablation in both right atrium (RA) and left atrium (LA)
- 71%
- LA GP ablation only after no response to RA ablation
- 16%
- GP localization: anatomical approach
- 90%
- GP localization: electrogram analysis
- 59%
- GP localization: pre-procedural imaging
- 20%
- GP localization: high-frequency stimulation
- 17%
- GP localization: spectral analysis
- 10%
- Discharge without anticoagulation or antiplatelet therapy
- 11%
- Perceive CNA as effective
- 80%
- Estimate <1% procedure-related complication rate
- 71%
- View CNA emerging as first-line therapy in the near future
- Half
