Efficacy of DE-MRI-Guided Fibrosis Ablation vs. Conventional Catheter Ablation of Atrial Fibrillation (DECAAF II)
To examine the efficacy of targeting atrial fibrosis tissue during an ablation procedure in treating persistent AF.
- Patients with persistent AF undergoing first AF ablation as per recent HRS consensus document. Persistent AF is defined by 7 days or more in AF as evidenced by either 1) rhythm strip or 2) written documentation.
- Must have some proportion of atrial fibrosis (not limited to advanced stage fibrosis).
