Radiofrequency catheter ablation in children can lead to coronary artery stenosis, a complication not previously reported. This risk highlights the need for caution when performing these procedures on young patients.
Area of Science:
- Pediatric Cardiology
- Electrophysiology
- Interventional Cardiology
Background:
- Coronary artery complications from radiofrequency catheter ablation (RFCA) are undocumented in pediatric populations.
- Animal studies have shown coronary artery lesions following endocardial RF current application.
Observation:
- Two pediatric patients with Ebstein's anomaly experienced asymptomatic coronary artery stenosis post-RFCA.
- The procedures involved ablation of right-sided accessory atrioventricular pathways using standard catheter technology.
Findings:
- Radiofrequency catheter ablation in children carries a risk of coronary artery stenosis.
- This complication was observed after ablation of right-sided accessory pathways.
Implications:
- Coronary artery stenosis is a significant potential complication of RFCA in pediatric patients.
- Clinicians should consider the risk of late coronary alterations when proposing RFCA for young individuals.
- This finding underscores the importance of long-term surveillance for coronary health after pediatric ablation procedures.
