The QDOT MICROTM Catheter is a novel open-irrigated contact force-sensing single-tip radiofrequency ablation catheter. It incorporates six thermocouples at its tip and offers temperature-controlled and very high-power short-duration (vHPSD) ablation with 90 Watts for 4 seconds to improve safety and efficacy of catheter ablation procedures. The QDOT MICROTM Catheter was recently evaluated for pulmonary vein isolation and safety, efficacy and long-term follow-up found promising results. Although the QDOT MICROTM Catheter was mainly designed for pulmonary vein isolation its versatility to treat atrial fibrillation as well as other types of arrythmias was recently evaluated by the FAST and FURIOUS study series and other studies and will be presented in this article.
