Anteroseptal accessory pathways are relatively rare. Because of the close proximity of the atrioventricular (AV) node, ablation of these accessory pathways has the potential to result in AV block. The anteroseptal region is adjacent to the noncoronary cusp, allowing anteroseptal accessory pathways to be ablated from the noncoronary cusp. A 34 year-old male patient with recurrent episodes of palpitation for approximately ten years was admitted to our department. Twelve lead-ECG was consistent with anteroseptal accessory pathway. Intracardiac recordings were also consistent with anteroseptal accessory pathway. In this case, we found an excellent AV relation while mapping the noncoronary cusp. Radiofrequency (RF) ablation was applied to this region. Pre-excitation was immediately disappeared during RF application. After RF ablation, there was no pre-excitation detectable by ECG. In this report, we present a case of anteroseptal accessory pathway that was successfully ablated from the noncoronary cusp.
