Implication

May serve as salvage for refractory right atrial appendage tachycardia; leaves open need for prospective validation of durability and safety.

Key Points

To evaluate surgical resection as an alternative treatment strategy for drug-refractory and catheter ablation-refractory focal atrial tachycardia originating from the right atrial appendage.
Conducted an electrophysiological study to identify the tachycardia mechanism and map the earliest endocardial activation site in a 44-year-old female.
Attempted repeated endocardial radiofrequency catheter ablation at the mapped focal origin at the apex of the right atrial appendage.
Performed surgical right atrial appendectomy following failed catheter ablation and examined the macroscopic anatomy of the resected tissue.
Endocardial radiofrequency catheter ablation failed due to anatomical obstruction, as the right atrial appendage cavity formed a dead-end before reaching the apex.
Surgical excision via right atrial appendectomy successfully terminated the incessant atrial tachycardia.

Structured PICO

Population

44-year-old female with incessant, drug-refractory atrial tachycardia originating from the apex of the right atrial appendage (n=1)

Intervention

Surgical right atrial appendectomy

Outcome

Termination of atrial tachycardia

Surgical right atrial appendectomy may be an effective treatment for focal atrial tachycardia originating from the right atrial appendage apex that is refractory to medical therapy and radiofrequency catheter ablation.
