Electrophysiology Study for Complex Supraventricular Tachycardia in Congenital Heart Disease Patients With Single‐Ventricle Physiology
Key result
Transcatheter ablation successfully eliminated supraventricular tachycardia in 85.7% of patients with single-ventricle complex congenital heart disease, with a 16.7% recurrence rate over 6 years.

Population
30 patients (mean age 7.1 years) with single-ventricle complex congenital heart disease who underwent electrophysiology studies and catheter ablation, followed for 6 years.
E
Exposure
Electrophysiology studies and transcatheter ablation

Outcome
Ablation success rate and recurrence rate
Transcatheter ablation is an effective treatment for complex supraventricular tachycardia in pediatric patients with single-ventricle physiology, achieving an 85.7% success rate.
Limitations
- limited vascular access
- risk of atrioventricular block
Cite This Study
Chiu et al. (2016) conducted a cohort in Complex congenital heart disease with single-ventricle physiology and supraventricular tachycardia (n=30). Electrophysiology studies and catheter ablation was evaluated on Successful elimination of SVT. Transcatheter ablation successfully eliminated supraventricular tachycardia in 85.7% of patients with single-ventricle complex congenital heart disease, with a 16.7% recurrence rate over 6 years.
