Ablation of an atriofascicular accessory pathway with a zero-fluoroscopy procedure

Publication date: Available online 22 April 2015 Source:Journal of Arrhythmia Author(s): Riccardo Proietti , Sylvia Abadir , Martin L. Bernier , Vidal Essebag A 16-year-old patient with recurrent palpitations and documented left bundle branch block superior axis wide complex tachycardia underwent an electrophysiological study and ablation with a zero-fluoroscopy procedure. The electrophysiological study showed a decremental antegrade conducting atriofascicular pathway. Three-dimensional CARTO-guided mapping of the tricuspid annulus in sinus rhythm was performed, and a distinct signal corresponding to the accessory pathway potential of the atriofascicular pathway was found in the posterolateral region. By using an SR0 sheath and a 4-mm-tip catheter, radiofrequency application was delivered at this point on the annulus and successfully eliminated conduction through the accessory pathway.
