Epicardial mapping and ablation may serve as an alternative approach for focal atrial tachycardias near the right atrial appendage root that resist endocardial ablation.
Chen et al. (2022) conducted a case report in Focal atrial tachycardia (n=1). Epicardial radiofrequency ablation was evaluated on Termination of tachycardia and freedom from recurrence. Epicardial mapping and radiofrequency ablation successfully terminated a focal atrial tachycardia adjacent to the sinoatrial node that was resistant to endocardial ablation, with no recurrence at 12 months.
