Condition(s) studied

Paroxysmal Atrial Fibrillation

Investigational drug(s) / intervention(s)

QDOT MicroTM catheterAI-guided ablation only for PVI

QDOT MicroTM catheter: Novel high power-short duration ablation catheter for atrial fibrillation

AI-guided ablation only for PVI: Ablation is the removal or destruction of something from an object by vaporization, chipping, erosive processes, or by other means.

Study summary

This study aims to investigate the effect of reducing ablation time for a hybrid approach of vHPSD and AI-guided ablation using the QDOT Micro catheter in PVI among patients with PAF.
