Brief Summary

Atrial fibrillation (AF) is a major cardiovascular disease with a prevalence of 1.7% of the total population in Korea, associated with 25% of ischemic stroke and 30% of heart failure, and is a major cardiovascular disease that doubles the risk of dementia. AF catheter ablation (AFCA) is an effective procedure that lowers the risk of heart failure mortality and cerebral infarction and improves cognitive or renal functions. However, the recurrence rate after the procedure is relatively high, especially in patients with long-standing persistent AF in which atrial remodeling has already progressed. Research on the prediction of treatment efficacy using artificial intelligence (AI) is being actively conducted around the world. We predicted the AFCA poor responders who will progress to permanent AF despite AFCA among a total of 3,372 patients included in the Yonsei AF Ablation cohort and the 2nd independent cohort with a long-term follow-up through AI with area under curve (AUC) 0.943. Therefore, in this prospective randomized clinical study, the difference between the patient selection for AFCA using AI algorithm and the clinical guidelines-based decision will be compared and evaluated in terms of long-term rhythm outcome.

Outcome Measures

Primary Outcomes (2)

  • Efficacy of Atrial Fibrillation Catheter Ablation(AFCA)

    Efficacy evaluation: Clinical recurrence rate - Defined as AF or atrial tachycardia lasting over 30 seconds after 3 months of procedure. Rhythm monitoring based on 2012 ACC/AHA/HRS guidelines as described above. 24-hour Holter ECG monitoring will be performed at 2-3 month and every 6 months within 2 years of procedure, Holter every 1 year after 2 years of procedure and ECG and monitoring with a Holter or an event recorder will be performed at any time if the patient complains of symptoms

    Up to 5 years

  • safety of Atrial Fibrillation Catheter Ablation(AFCA)

    Safety Assessment: Incidence of procedure-related complications within 30 days of procedure (thoracotomy, cerebral infarction, pericardial effusion or pericardial tamponade, inguinal puncture site hematoma, and vascular complications)

    Up to 5 years

Secondary Outcomes (5)

  • Comparison of procedure time, ablation time and hospitalization period

    Immediate after procedure

  • Anti-arrhythmic drug or anticoagulation therapy related complication rate

    1 week, 3, 6, 12, 18, 24, 36 months after procedure

  • Re-hospitalization rate of electrical cardioverson after the procedure

    1 week, 3, 6, 12, 18, 24, 36 months after procedure

  • number of electrical cardioversion after the procedure

    1 week, 3, 6, 12, 18, 24, 36 months after procedure

  • Major cardiovascular event rate - Death, myocardial infarction, coronary angioplasty, and re-hospitalization for arrhythmia and heart failure

    Immediate after procedure

Interventions

1. Patient selection for Atrial Fibrillation Catheter Ablation(AFCA) 2. AI-guided prediction for poor responder of AFCA in the outpatient clinic 3. Sharing information on the AI prediction with the patient and family member 4. AFCA after consent to the procedure 5.
