Feasibility of RF ablation using a simplified two‐catheter technique from a femoral approach was studied in 97 consecutive patients with a manifest or concealed accessory pathway located at the anteroseptal, mid‐septal, and para‐Hisian areas. BF was applied at the site with the shortest V‐delta interval or the earliest retrograde atrial activation during orthodromic tachycardia or right ventricular pacing. Ablation was initially successful in 88 of’97 patients (91 %). Success rate was 94% (16/17) for anteroseptal. 94% (39/43] for para‐Hisian, and 89% (33/37) for mid‐septal accessory pathways, without differences between manifest and concealed pathways for any of the locations. Mean number of BF pulses was 8 ± 5 for anteroseptal, 6 ± 6 for mid‐septal, and 12 ± 13 for para‐Hisian accessory pathways. Two patients (2%) required implantation of a permanent pacemaker for complete A V block. At a mean follow‐up of 27 ± 14 months, four patients with previous manifest preexcitation experienced resumption of intermittent preexcitation, but only one required a second successful procedure for recurrence of palpitations. RF ablation can be used effectively and without impairment of normal AV conduction in the majority of patients with anteroseptal, para‐Hisian, and mid‐septal accessory pathways using a simplified two‐catheter technique from a femoral approach.
