Pulmonary Vein Isolation Strategy of Very High Power Short Duration in Patients With Paroxysmal Atrial Fibrillation: Q-INDEX 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.
Inclusion: Patients undergoing PVI for PAF.
Exclusion: Patients with previous ablation or surgery for AF; Patients with intracardiac thrombus or thromboembolic events within the previous 90 days; Patients with cardiac surgery or acute coronary syndrome within the previous 90 days; Patients with left ventricular ejection fraction less than 35%; Aged less than 19 years; Patients with persistent AF; Patients with contraindication(s) for using oral anticoagulants; Patients with LA anteroposterior diameter of more than 55 mm; Pregnants or those who plan to become pregnant during the study; Life expectancy less than a year.
