Fluoroless cryo-ablation of para-Hisian accessory pathway

Abstract

We present a case of para-Hisian accessory pathway ablation in a patient with Wolff-Parkinson-White syndrome, which was performed with cryoablation to reduce the possibility of collateral damage to the conduction system of the heart. We also used fluoroless approach to exclude possible harm from radiation exposure, using only intracardial electrograms and three-dimensional (3D) electro-anatomic mapping system to navigate the catheters in the heart.
