Abstract
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.
