Does radiofrequency ablation achieve long-term success in patients with focal atrial tachycardias arising from the right atrial appendage?
Focal atrial tachycardias from the right atrial appendage are rare (3.8%) but can be successfully treated long-term with radiofrequency ablation, often requiring irrigated catheters.
The RAA is an uncommon site of origin for focal AT (3.8%). It can be suspected as a potential anatomic site of AT origin from the characteristic P wave and activation timing. Irrigated ablation catheters are often required for successful ablation. Long-term success was achieved with focal ablation in all patients.
