High Power Short Duration Ablation for Atrial Fibrillation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effects of a novel ablation technique using very high power and short duration to treat patients with paroxysmal atrial fibrillation. The approach employs the QDOT Micro catheter and AI-guided ablation to enhance procedural efficiency and effectiveness. By reducing the ablation time while maintaining safety and efficacy, the study aims to improve patient outcomes in rhythm control. The research will compare this method to conventional ablation techniques to assess its viability and success rates.
