A total number of 30 patients will undergo catheter Ablation for persistent AF. Pre-procedural cardiac MRI will be performed with late-gadolinium enhancement to visualize the individual amount and distribution of fibrosis in the right and left atrium. CARTOFINDER-guided mapping will be performed during the ablation procedure followed by AF ablation. The individual relationship between atrial fibrosis and potential ablation targets will be accessed.
Single center observational study to compare the relationship between atrial fibrosis and potential ablation targets from CARTOFINDER.
