An accessory pathway has been recognized as a strand of (usually) working myocardial cells connecting atrial and ventricular myocardium across the electrically insulating fibro-fatty tissues of the AV junction at anatomic sites not intended by nature (that is remote from the locus of the bundle of his) (Michael et al., 1999). Successful ablation of accessory pathways is defined as ablation of anterograde and retrograde connection over the accessory pathway and tachycardia control without medication. Radiofrequency catheter ablation is now the procedure of choice for patients with avariety of tachycardia (Brandao and Carrageta, 1999). The success rates for catheter ablation of right free wall accessory pathways is somewhat lower than that for accessory pathways at other locations: 88% versus 97% for left free wall, 96% for anteroseptal, and 91% for posteroseptal (Rosenthal and Calkins, 1997). After successful RF ablation of an AP. Further investigation is warranted to confirm the persistence of successful ablation.
