Key result
PFA successfully terminates incessant atrial tachycardia from the right atrial appendage without complications.
Why the study?
Atrial tachycardia occurring from the right atrial appendage is relatively uncommon, and catheter ablation is complicated by its anatomic characteristics.
Does pulsed field ablation using a circular mapping catheter terminate incessant atrial tachycardia originating from the right atrial appendage?

Does pulsed field ablation using a circular mapping catheter terminate incessant atrial tachycardia originating from the right atrial appendage?
Pulsed field ablation using a circular mapping catheter may be a safe and effective alternative strategy for ablating atrial arrhythmias originating from the right atrial appendage.
May support PFA feasibility for RAA tachycardia; leaves open prospective validation before broader adoption.
Introduction: Atrial tachycardia(AT) occurring from the right atrial appendage(RAA) is relatively uncommon, while the catheter ablation is complicated by the anatomic characteristics. Methods: We reported a case of 60-year-old male patient who was admitted with incessant AT. Results: The tachycardia activation mapping demonstrated that the AT originated from the tip of RAA. Pulsed field ablation(PFA) using the circular mapping&PFA catheter terminated AT without any complication. Conclusions: This case corroborates that PFA might be an alternative strategy for ablation of atrial arrhythmia originating from the atrial appendage.
