Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients aged 20 to 80 years with paroxysmal atrial fibrillation (sustained for < 7 days) who are candidates for catheter ablation. 2. Patients with atrial fibrillation and a left atrial size < 50 mm. 3. Patients with paroxysmal atrial fibrillation who have experienced recurrence despite anti-arrhythmic drug therapy, or for whom anti-arrhythmic drug therapy is contraindicated or not tolerated. 4. Patients who are eligible for anticoagulation therapy (antithrombotic treatment for the prevention of ischemic stroke).
Exclusion criteria
Exclusion criteria: 1. Patients with atrial fibrillation and a left atrial anteroposterior diameter = 50 mm 2. Atrial fibrillation associated with severe congenital heart disease or structural heart disease with significant hemodynamic impact 3. Patients with severe renal dysfunction or those unable to undergo contrast-enhanced CT imaging 4. Patients with active internal bleeding 5. Contraindications to anticoagulation therapy (for stroke prevention) or anti-arrhythmic drug therapy 6. Valvular atrial fibrillation (mitral stenosis > grade 2, mechanical heart valve, or prior mitral valve repair) 7. Patients with clinically significant severe comorbid conditions 8. Patients with an expected life expectancy of less than 1 year 9. Patients with drug or alcohol abuse 10. Patients unable to read the informed consent form (e.g., illiteracy, foreign nationals unable to understand the language) 11. Any other condition that, in the investigator’s judgment, makes the patient unsuitable for participation in the clinical trial
