目的:研究心脏瓣膜手术同期行射频消融术治疗永久性心房纤颤(房颤)术后脑血管事件的发生。方法:回顾2003年1月至2006年12月758例瓣膜病合并房颤病例,其中行瓣膜手术+房颤射频消融374例(射频消融组),仅行瓣膜手术384例(对照组)。术后随访6～54个月,平均(32±6.23)个月,对比分析2组病例术后脑血管事件随访数据。结果:术后随访证实消融组在术后脑血管事件发生率、生存率、窦性心律转复率等均优于对照组。结论:心脏瓣膜置换术同期行射频消融术治疗永久性房颤的远期疗效确切,可降低脑血管事件的发生,并提高远期生存率、窦性心律转复率。
Objective: To study the incidence of cerebrovascular events following permanent atrial fibrillation (AF) after simultaneous cardiac valve surgery with radiofrequency catheter ablation. Methods: From January 2003 to December 2006, 758 patients with valvular heart disease complicated with atrial fibrillation were retrospectively reviewed. Among them, 374 patients underwent valvular surgery plus atrial fibrillation radiofrequency ablation, and only 384 patients underwent valvular surgery (control group). The patients were followed up for 6 to 54 months with an average of (32 ± 6.23) months. The follow-up data of cerebrovascular events in two groups were compared. Results: Postoperative follow-up confirmed that the incidence of cerebrovascular events, survival rate and sinus rhythm recovery rate in ablation group were superior to those in control group. CONCLUSION: The long-term curative effect of simultaneous replacement of heart valve with radiofrequency catheter ablation on permanent atrial fibrillation can reduce the incidence of cerebrovascular events and improve long-term survival and sinus rhythm recovery rate.
