Epicardial ablation in high-risk Brugada syndrome to prevent ventricular fibrillation: results from a randomized clinical trial

Study Overview

This study focused on epicardial ablation for patients with Brugada syndrome (BrS), a condition that can lead to dangerous heart rhythms. The goal was to see if this treatment could help reduce the risk of ventricular fibrillation (VF), a serious heart issue.

Study Design

The research involved a randomized trial with two groups: one group received epicardial ablation, while the other did not. All participants had an implantable cardioverter-defibrillator (ICD) due to previous heart issues. The study started in September 2017 and ended early in February 2024.

Key Findings

  • Out of 40 patients, 26 underwent ablation and 14 were in the control group.
  • After an average follow-up of 4 years, 96% of patients in the ablation group did not experience VF again, compared to only 50% in the control group.
  • There were some complications, including one patient needing treatment for fluid around the heart and 33% experiencing major ICD-related issues.
  • No unexplained deaths occurred during the follow-up period.

Conclusion

The results suggest that epicardial ablation significantly reduces the chances of VF recurrence in high-risk BrS patients compared to just relying on ICD therapy.

Practical Healthcare Solutions

Measurable Outcomes

Clinics should aim for:

  • High rates of VF freedom post-ablation (target: >90%).
  • Minimized complications related to the procedure and ICD.
  • Improved quality of life for patients.
