Feasibility of single-session ablation in Ebstein's anomaly with multiple pathways; leaves open generalizability and durability in larger cohorts.
This report describes the case of a 19-year-old patient with Ebstein's anomaly, who had an unusual combination of a right atriofascicular (Mahaim) and two ipsilateral right atrioventricular (Kent) accessory pathways participating in three types of antidromic and orthodromic reciprocating tachycardias in the absence of retrograde conduction over the bundle of His-atrioventricular node axis. All three pathways were ablated in a single session using temperature-guided radiofrequency current.

Hluchý et al. (1996) conducted a case report in Ebstein's anomaly with right atriofascicular (Mahaim) and two right atrioventricular (Kent) accessory pathways (n=1). Temperature-guided radiofrequency catheter ablation was evaluated on Ablation of all three pathways. Temperature-guided radiofrequency catheter ablation successfully eliminated a right atriofascicular and two right atrioventricular accessory pathways in a single session.
