Renal impairment is associated with poor prognosis in the setting of atrial fibrillation (AF). While AF catheter ablation is an effective treatment modality for AF burden reduction and improvement of symptoms, changes in renal function after catheter ablation and their association with rhythm outcome have not been studied in a large contemporary AF ablation cohort. ⋯ In patients after AF catheter ablation, eGFR changes during mid-term follow-up are associated with AF recurrences, CHADS2 and CHA2DS2-VASc scores.
