Introduction: Chronic kidney disease (CKD) and atrial fibrillation (AF) often co-exist. We studied the association of CKD with atrial fibrosis and the effect of AF ablation on kidney function. Methods: AF Patients who had a pre- and post-ablation serum creatinine and who completed a late gadolinium enhancement cardiac MRI (LGE-MRI) prior to ablation were included. Estimated Glomerular Filtration Rate (eGFR) was calculated and CKD was staged using the National Kidney Foundation guidelines. Patient with eGFR
