J. Martinezleon et al., KENT BUNDLE VISUALIZED IN-SITU AT OPERATION AFTER UNSUCCESSFUL RADIOFREQUENCY ABLATION, The Annals of thoracic surgery, 59(1), 1995, pp. 218-220
Kent bundles are seldom visualized at operation, but, in the patient d
escribed, the pathway was subepicardial, running superficial to the ri
ght coronary artery. This was probably why radiofrequency ablation fai
led. When this unusual pathway course is encountered, the epicardial a
pproach should be used at operation.
