High-power and short-duration ablation with the Qdot+ algorithm for pulmonary vein isolation and the right superior ganglion plexus ablation without fluoroscopy

Abstract

In this report we present pulmonary vein and posterior box isolation together with the right superior ganglion plexus ablation using the Qdot Micro catheter without fluoroscopy. We describe different possibilities of this new technology for catheter ablation. The main advantages of this catheter to potentially increase ablation safety and effectiveness are discussed. Specifically, the possibility to perform high-density mapping with the lowest available distance between points. Furthermore, the possibility to decrease the risk of collateral tissue damage and to improve atrial linear lesions contiguity, transmurality and durability due to the dominance of resistive heating supported by the feedback temperature control. Finally, the possibility to shorten the procedure and fluoroscopy duration due to the high shortening of application duration to 4 seconds only.
