“…In six patients, a late coronary angiogram was performed [11][12][13][14][15] Stabilizing and positioning the catheter pose various difficulties. Displacement of the catheter is very frequent in the right parietal accessory pathways.…”

“…Therefore, the sharp potential interposed between ventricular and atrial electrograms during tachycardia at the epicardial site became independent of both atrial and ventricular activation after successful ablation. 1 This potential probably represents accessory pathway activity recorded epicardially from the distal CS. Pathologic studies have shown that the histologic substrate of accessory pathways may be partially or completely epicardial, 8 thus accounting for the occasional unsuccessful endocardial ablation approach and the need for RF delivery into the CS, 9 as in this case.…”

Mapping in a patient undergoing radiofrequency ablation for a left-sided concealed accessory pathway showed that the site with the shortest VA conduction time was in the great cardiac vein. Epicardial radiofrequency delivery at that site was successful. After ablation, a potential dissociated from both atrial and ventricular activity during sinus rhythm and atrial pacing was noted on the distal bipole of the ablation catheter. During incremental ventricular pacing, intermittent ventricular to potential conduction was observed. This indicates complete block at the atrial-accessory pathway interface and impaired conduction at the ventricular interface. This dissociated activity originating neither from the ventricle nor from the atria provides evidence of automatic accessory pathway activity.

The anode was a large skin electrode (81cm2, R-6, NIKOMED), positioned over the left scapular or left axillary area for right intermediate septal or left parietal accessory pathways; over the left anterolateral chest wall for right anteroseptal accessory pathways; over the right anterolateral chest wall for right anterior accessory pathways; and over the right back for right posterior accessory pathways.…”
