Key result
Thoracoscopic clamp radiofrequency ablation successfully terminated refractory atrial tachycardia originating from the right atrial appendage and restored sinus rhythm after catheter ablation failed.
Why the study?
Atrial tachycardia originating from the right atrial appendage has a higher probability of catheter ablation failure.
Does thoracoscopic clamp radiofrequency ablation terminate atrial tachycardia originating from the right atrial appendage after catheter ablation failure in a pediatric patient?

Does thoracoscopic clamp radiofrequency ablation terminate atrial tachycardia originating from the right atrial appendage after catheter ablation failure in a pediatric patient?
Thoracoscopic clamp radiofrequency ablation may be an effective alternative for pediatric patients with right atrial appendage tachycardia failing transendocardial ablation.

Thoracoscopic ablation may succeed after failed endocardial attempt in right atrial appendage tachycardia; hypothesis-generating for pediatric refractory cases.
Atrial tachycardia originating from the right atrial appendage has a higher probability of failure of catheter ablation. Here we report a case of a 13-year-old boy with incessant tachycardia, complicated by heart enlargement, and heart failure. Electrophysiological examination showed that atrial tachycardia (AT) originated from the apex of the right atrial appendage, and endocardial catheter ablation was ineffective. After thoracoscopic approach, the right atrial appendage was successfully ablated with bipolar radiofrequency ablation forceps, atrial tachycardia was terminated and sinus rhythm was restored. Within 3 months since the patient was discharged from the hospital, no arrhythmia occurred and the heart structure returned to normal. Thus, thoracoscopic clamp radiofrequency ablation may be a reasonable choice for young patients with atrial tachycardia originated from the right atrial appendage when transendocardial ablation is not effective.

Luo et al. (2021) conducted a case report in Atrial tachycardia originating from the right atrial appendage (n=1). Thoracoscopic clamp radiofrequency ablation was evaluated on Termination of atrial tachycardia and restoration of sinus rhythm. Thoracoscopic clamp radiofrequency ablation successfully terminated refractory atrial tachycardia originating from the right atrial appendage and restored sinus rhythm after catheter ablation failed.
