First successful ablation of atrial tachycardia from right atrial
appendage using circular pulse field ablation catheter
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.
