Abstract：Objective To analyze the clinical effect of valve surgery combined with simultaneous radiofrequency ablation in the treatment of atrial fibrillation and its effect on patients with cardiac rhythm. Methods A total of 60 patients with atrial fibrillation in the First Affiliated Hospital of Hu′nan Normal University from February 2018 to June 2021 were selected as research subjects, and they were divided into the observation group and the control group by random number table method, with 30 patients in each group. The observation group was treated with valve surgery and modified labyrinth bipolar radiofrequency ablation at the same time, while the control group was treated with valve replacement and left atrial appendage ligation. The cardiopulmonary bypass time, mitral valve replacement (MVR) time, double valve replacement (DVR) time, ventilator use time, hospital stay, quality of life, the incidence of complications and changes of cardiac rhythm after treatment were compared between the two groups. Results There were no significant differences in the ventilator use time and hospital stay between the two groups (P＞0.05). The MVR and DVR of the observation group were longer than those of the control group, and the differences were statistically significant (P＜0.05).There were no significant differences in the quality of life scores of physiological function, health self-assessment,physical pain, life vitality, physiological function, social function, emotional role, mental health score and total score between the two groups before treatment (P＞0.05). The scores of physiological function, health self-assessment, life vitality, physiological function, social function, emotional role, mental health and total scores in the quality of life scores in the observation group after treatment were higher than those in the control group, and the differences were statistically significant (P＜0.05). The scores of physiological function, health self-assessment, life vitality, physiological function, social function, emotional role, mental health and total score in the quality of life scores of the observation group after treatment were higher than those before treatment, and the differences were statistically significant (P＜0.05). Except for physical pain, the scores of other dimensions and total scores in the control group after treatment were higher than those before treatment, and the differences were statistically significant (P＜0.05). There were 27 cases of sinus rhythm, 2 cases of atrial fibrillation and 1 case of atrial flutter in the observation group. In the control group, there were 13 cases of sinus rhythm, 15 cases of atrial fibrillation and 2 cases of atrial flutter. There was significant difference in the changes of postoperative cardiac rhythm between the two groups (χ2=15.175, P=0.001). Conclusion Radiofrequency ablation is one of the important surgical methods in the treatment of atrial fibrillation. Valve surgery combined with simultaneous modified radiofrequency ablation is safe and effective, which is conducive to further improve the surgical effect. It can effectively alleviate the symptoms of atrial fibrillation after operation, and the incidence of complications is relatively low and mild. It can be used as the first choice for valve disease complicated with atrial fibrillation.
