Key result
Electroanatomic mapping-guided RFCA successfully treats right-sided AVRT in Ebstein's anomaly after conventional mapping fails.
Why the study?
Ebstein's anomaly is highly associated with AVRT due to an atrioventricular accessory pathway, and conventional mapping techniques may fail to ablate the pathway successfully.
Does radiofrequency catheter ablation using an electroanatomic mapping system improve ablation success in a patient with Ebstein's anomaly and AVRT?

Does radiofrequency catheter ablation using an electroanatomic mapping system improve ablation success in a patient with Ebstein's anomaly and AVRT?
Electroanatomic mapping can facilitate successful radiofrequency catheter ablation of accessory pathways in patients with Ebstein's anomaly when conventional mapping fails.
Ai et al. (2002) conducted a case report in Ebstein's anomaly with atrioventricular reciprocating tachycardia (AVRT) (n=1). Radiofrequency current catheter ablation using an electroanatomic mapping system was evaluated on Successful ablation of the accessory pathway. Radiofrequency catheter ablation using an electroanatomic mapping system successfully treated AVRT due to a right-sided accessory pathway in a patient with Ebstein's anomaly.
