Conclusion:
The QDOT MICROTM Catheter offers vHPSD (90W/4s, QMODE+) as well as conventional temperature-controlled (QMODE, AI guided) ablation and showed safety and efficacy for PVI in a several studies. Beside those promising observations its ability to treat also other types of arrythmias including typical common type atrial flutter, macro-reentrant atrial tachycardia, supraventricular tachycardia with accessory pathway as well as PVCs was recently evaluated by preliminary case reports and studies (FAST and FURIOUS studies). Although the results are promising further multicenter evaluations are necessary to draw final conclusions.
