BACKGROUND: Accessory pathway (AP)-related arrhythmias are frequent in patients with Ebstein anomaly (EA), and arrhythmia recurrence after catheter ablation remains high despite current technological developments.
METHODS: Case series report of patients with EA who were taken to an accessory pathway ablation procedure and where clinical, procedure, and follow-up data are described. In all cases, mapping of the true tricuspid annulus guided by intracardiac ultrasound was used.
RESULTS: Six patients with EA underwent an ablation procedure using ICE to delineate the true tricuspid annulus. The duration of the procedure was 253.33 ± 60.92 min, with an acute success of 100%. After a mean follow-up of 16.16 ± 7.7 months, no recurrences of tachycardia were documented, and all patients were free of antiarrhythmic medications.
CONCLUSION: Intraprocedural ICE helps to delineate the true tricuspid annulus that contains the APs, facilitating mapping and ablation. We hypothesize that the systematic use of ICE in this scenario improves ablation efficacy while reducing complications, but this must be verified in prospective studies.
