Abstract:
Objective To investigate the feasibility, safety and effectiveness of radiofrequency ablation of atrial fibrillation with mitral valve replacement under totally thoracoscopic surgery. Methods The clinical data of 107 patients with rheumatic mitral disease and atrial fibrillation who underwent mitral valve replacement and radiofrequency ablation at the same time in our hospital from January 2014 to October 2018 were retrospectively analyzed. The patients were divided into two groups: a totally thoracoscopic surgery group (n=51, including 20 males and 31 females, aged 50.57±5.24 years) and a median sternotomy group (n=56, including 21 males and 35 females, aged 52.12±5.59 years) according to the surgical methods. The preoperative, intraoperative and postoperative data of the patients were compared. Results All operations were successfully completed without death. In terms of bleeding volume, drainage volume, ventilator-assisted breathing time, hospital stay and incision length, the totally thoracoscopic surgery group was better than the median sternotomy group, and the difference was statistically significant (P<0.05). The cardiopulmonary bypass time and radiofrequency ablation time in the totally thoracoscopic surgery group were longer than those in the median sternotomy group (P<0.05). There was no significant difference in the operation time, aortic occlusion time, postoperative complications, left ventricular ejection fraction, left atrial diameter and sinus rhythm maintenance between the two groups (P>0.05). There was no atrioventricular block, pulmonary vein stenosis, atrioesophageal fistula, coronary artery injury, stroke or hemorrhage during the follow-up. Conclusion Radiofrequency ablation of atrial fibrillation with mitral valve replacement under totally thoracoscopic surgery is safe and effective, and it is worthy of clinical application.
