Insights
Cardioneuroablation (CNA) for vasovagal syncope (VVS) is increasingly used in Europe. While perceived as effective and safe, standardization of procedures and patient management is needed.
Area of Science:
- Cardiology
- Autonomic Nervous System Research
- Interventional Electrophysiology
Background:
- Recurrent vasovagal syncope (VVS) significantly impacts quality of life.
- Cardioneuroablation (CNA) targets parasympathetic cardiac autonomic nervous system modulation for VVS.
- Current European utilization of CNA requires comprehensive assessment.
Purpose of the Study:
- To provide a comprehensive overview of current Cardioneuroablation (CNA) utilization across Europe.
- To assess current practices, perceived efficacy, and safety of CNA for VVS.
- To identify areas for standardization in CNA procedures.
Main Methods:
- A survey was distributed to 202 participants across 40 European countries.
- The survey collected data on CNA indications, procedural techniques, and endpoints.
- Data on peri-procedural management and perceived outcomes were analyzed.
Main Results:
- Half of respondents performed CNA in the past year, indicating its role as a treatment option.
- Seventy-one percent systematically target ganglionated plexuses (GPs) in both atria; anatomical and electrogram approaches dominate localization.
- CNA is perceived as effective (80%) and safe (<1% complications), with high future expectations, though heterogeneity in practice exists.
Conclusions:
- This survey provides a snapshot of current CNA implementation in Europe.
- Significant heterogeneity exists in indications, procedural workflow, and endpoints for CNA.
- Standardization of procedural protocols and peri-procedural patient management is crucial for advancing CNA.
Aims:
Cardioneuroablation (CNA) is a catheter-based intervention for recurrent vasovagal syncope (VVS) that consists in the modulation of the parasympathetic cardiac autonomic nervous system. This survey aims to provide a comprehensive overview of current CNA utilization in Europe.
Methods And Results:
A total of 202 participants from 40 different countries replied to the survey. Half of the respondents have performed a CNA during the last 12 months, reflecting that it is considered a treatment option of a subset of patients. Seventy-one per cent of respondents adopt an approach targeting ganglionated plexuses (GPs) systematically in both the right atrium (RA) and left atrium (LA). The second most common strategy (16%) involves LA GP ablation only after no response following RA ablation. The procedural endpoint is frequently an increase in heart rate. Ganglionated plexus localization predominantly relies on an anatomical approach (90%) and electrogram analysis (59%). Less utilized methods include pre-procedural imaging (20%), high-frequency stimulation (17%), and spectral analysis (10%). Post-CNA, anticoagulation or antiplatelet therapy is prescribed, with only 11% of the respondents discharging patients without such medication. Cardioneuroablation is perceived as effective (80% of respondents) and safe (71% estimated <1% rate of procedure-related complications). Half view CNA emerging as a first-line therapy in the near future.
Conclusion:
This survey offers a snapshot of the current implementation of CNA in Europe. The results show high expectations for the future of CNA, but important heterogeneity exists regarding indications, procedural workflow, and endpoints of CNA. Ongoing efforts are essential to standardize procedural protocols and peri-procedural patient management.
