Paediatric catheter ablation guided by electroanatomical mapping with limited fluoroscopy: a single centre experience

Area of Science:

• Pediatric Cardiology
• Electrophysiology
• Cardiac Ablation

Background:

• Catheter ablation is a preferred treatment for pediatric arrhythmias.
• It offers high success and low complication rates.
• This study evaluates outcomes at a single center.

Purpose of the Study:

• To assess the outcomes of pediatric patients undergoing electrophysiology studies and catheter ablation.
• To compare institutional results with existing literature.

Main Methods:

• Retrospective screening of 586 pediatric patients (2017-2024).
• Exclusion of patients with ICDs, pacemakers, or ventricular arrhythmias.
• Analysis of ablation procedures for various arrhythmias, including atrioventricular re-entry tachycardia and atrioventricular nodal re-entry tachycardia.

Main Results:

• Atrioventricular re-entry tachycardia (AVRT) treated in 49% of patients (primarily Wolff-Parkinson-White syndrome).
• Atrioventricular nodal re-entry tachycardia (AVNRT) treated in 45% of patients.
• Fluoroscopy used in 12.8% of cases, with a mean duration of 5.2 minutes.

Conclusions:

• Catheter ablation at this institution demonstrates acute success rates comparable to published data.
• Recurrence rates are also similar to previous studies.
• The findings support catheter ablation as a safe and effective pediatric arrhythmia treatment.
