Abstract Objective To identify the risk factors for postoperative atrial fibrillation (AF) recurrence in nonvalvular AF patients undergoing radiofrequency catheter ablation (CA). Methods We retrospectively reviewed the data from 426 of 450 AF patients who underwent CA. Patients were divided into two groups according to recurrence after the operation; the risk factors for AF recurrence were analyzed. A stratification system for lesions was created based on the cutoff of the risk factors; the associations among the subgroups and the AF recurrence rate were analyzed. Results AF recurrence occurred in 98 (23.0%) patients. Univariate analysis demonstrated that AF type, hypertrophic cardiomyopathy, left atrial diameter (LAD), left ventricular ejection fraction (LVEF), serum albumin, and D‐dimer concentrations were associated with AF recurrence. AF type (OR =2.907, p
