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 fanny pack 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 Sheets 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.
