Abstract
Radiofrequency catheter ablation of concealed posteroseptal accessory pathways (APS) has been a relatively difficult task for electrophysiologists. Without a detailed mapping procedure, the left versus the right posteroseptal AP could not be distinguished. We investigated the electrophysiological characteristics of concealed posteroseptal APs and defined criteria from baseline parameters to predict the successful ablation site. Validity of the criteria was prospectively verified. Eighty-nine consecutive patients with a single concealed posteroseptal AP underwent successful radiofrequency catheter ablation. Of the initial 48 patients (group 1), the right posteroseptal area was first mapped. If no ideal electrogram could be obtained, or after several ineffective radiofrequency pulses, the left posteroseptal area was then mapped. Special attention was paid to the stability of the coronary sinus catheter with the most proximal electrode straddling the ostium, verified by coronary sinus venography, in all patients. Six patients (12.5%) had the earliest retrograde atrial activation at the middle electrode of the coronary sinus catheter, and successful ablation could only be achieved at the left posteroseptal area. For patients who pr...Continue Reading
