About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients undergoing PVI for PAF

Disqualifiers

Aged less than 19 years

Patients with persistent AF

Patients with previous ablation or surgery for AF

Patients with intracardiac thrombus or thromboembolic events within the previous 90 days

Trial design

Design model

Crossover

Treatments tested in this trial

  • QDOT MicroTM catheter

    Device

    Novel high power-short duration ablation catheter for atrial fibrillation

  • AI-guided ablation only for PVI

    Device

    Ablation is the removal or destruction of something from an object by vaporization, chipping, erosive processes, or by other means.

Treatment groups

150 Participants
are divided into 3 treatment groups
Group A: vHPSD ablation only for PVIExperimental treatment 1 intervention
Group B: vHPSD and AI-guided ablation for PVIExperimental treatment 2 interventions
Group C: AI-guided ablation only for PVIExperimental treatment 1 intervention
