Inclusion criteria
Inclusion criteria: 1) Age range: 18-75 years old (inclusive); 2) The clinical diagnosis is persistent or long-term persistent atrial fibrillation that is not permanent. 3) Voluntarily participated in this experiment and signed the informed consent form; 4) Willing to comply with the relevant requirements of this experiment and cooperate in completing the corresponding follow-up.
Exclusion criteria
Exclusion criteria: 1) Atrial fibrillation caused by electrolyte imbalance, thyroid disease, reversible or non cardiac reasons; 2) Clearly identify subjects who require ablation therapy in areas outside the pulmonary vein, superior vena cava, and left atrial posterior wall, such as the tricuspid valve isthmus (CTI) region, to treat supraventricular tachycardia (such as atrioventricular reentry tachycardia, atrioventricular nodal reentry tachycardia, etc.), ventricular tachycardia, and Wolff Parkinson White syndrome; 3) The clinical diagnosis is permanent atrial fibrillation; 4) Severe left atrial enlargement (left atrial anterior posterior diameter>50mm); 5) Severe mitral regurgitation (regurgitation area>8cm2); 6) Subjects who have undergone heart related surgeries such as atrial/ventricular incision, atrial septal defect repair, patent foramen ovale closure, left atrial appendage closure, or heart valve related surgeries such as heart valve repair/replacement and are not suitable for catheter ablation in the past; 7) Subjects who plan to undergo cardiac related surgeries such as heart transplantation, left atrial appendage occlusion, permanent pacemaker implantation, or other major surgeries that affect ablation therapy within the next 12 months; 8) Subjects with significant congenital abnormalities in cardiac anatomy that hinder the entry of ablation catheters into the target ablation area; 9) Subjects with intracardiac thrombosis, myxoma, atrial patch, occluder or other conditions that hinder catheter insertion or operation; 10) Subjects with implantable pacemakers, implantable cardiodefibrillators (ICDs), or other implantable metal cardiac devices that may interfere with the pulse energy field; 11) Subjects with severe lung diseases (such as restrictive pulmonary disease, chronic obstructive pulmonary disease) or other lung diseases or functional impairments that cause serious chronic symptoms, such as significant pulmonary vein abnormalities, pulmonary vein stenosis, etc., that hinder ablation therapy; 12) Subjects with serious obstruction of vascular access (such as implanted inferior vena cava filters, intramural thrombosis, etc.); 13) Subjects with severe coagulation dysfunction, bleeding tendency, or contraindications to anticoagulant drugs such as heparin, warfarin, or dabigatran; 14) Subjects with active systemic infections; 15) Uncontrollable hypertension (sustained systolic blood pressure = 180mmHg or sustained diastolic blood pressure = 110mmHg); 16) Subjects with severe liver and kidney dysfunction; 17) Screening subjects with a history of systemic thromboembolism (including TIA) within the previous month; 18) Screening for subjects with unstable angina or those who have experienced acute myocardial infarction within the previous 3 months; 19) Select subjects who have undergone percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) within the previous 3 months; 20) Subjects who are currently participating in clinical studies of other devices or drugs before screening; 21) Female participants of childbearing age who are pregnant, breastfeeding, or planning to conceive; 22) Subjects with an expected lifespan of less than 12 months; 23) Other subjects who have been determined by the researchers to be unsuitable for participation in this trial.
