Why the study?
Radiofrequency catheter ablation of atrial tachycardia originating from the right atrial appendage often yields suboptimal success rates due to complex anatomical structure.
Does bipolar radiofrequency ablation via pericardium pathway successfully treat atrial tachycardia originating from the right atrial appendage?
Does bipolar radiofrequency ablation via pericardium pathway successfully treat atrial tachycardia originating from the right atrial appendage?
Bipolar radiofrequency ablation via the pericardium pathway may offer a promising approach for treating complex atrial tachycardias originating from the right atrial appendage.

May succeed where endocardial fails for right atrial appendage tachycardia; extends options but leaves open broader applicability.
Atrial tachycardia originating from the right atrial appendage was first reported more than a decade ago, which had been observed to occur more frequently in younger populations. Radiofrequency catheter ablation of this type of tachycardia often yielded suboptimal success rates, largely attributable to the complex anatomical structure of the right atrial appendage. In this report, we presented a successful case of bipolar radiofrequency ablation for atrial tachycardia arising from the right atrial appendage, which might offer a promising approach for the treatment of similar cases in the future.
