Ablation of a therapy-resistant posteroseptal accessory atrioventricular pathway: Going for gold

Abstract

Posteroseptal accessory pathways are sometimes resistant to ablation because of the complex anatomy of this region. Ex-vivo experiments have demonstrated that gold-tip radiofrequency ablation catheters create deeper lesions than conventional platinum-iridium tip catheters.This case of a 62-year-old man with Wolf-Parkinson-White syndrome illustrates that the ability to create such lesions can be a very useful option when previous attempts with platinum-iridium tip catheters have failed.

Key Words:

• Radiofrequency ablation
• Wolf-Parkinson-White syndrome
• gold-tip catheter
• posteroseptal accessory pathway
