【摘要】 目的 探讨瓣膜置换手术同期直视射频消融治疗房颤影响因素。方法 2010年1月至2013年12月共完成100例辫膜疾病手术治疗,同时术中直视射频消融治疗房颤,术后随访6~33个月,平均(19.8±8.7)个月,其中70例患者维持窦性心率,30例患者再次转为房颤心率。回顾两组患者的左房直径、房颤病史的长短、年龄、性别、随访时间、瓣膜置换类型。结果 两组患者年龄、性别、随访时间、瓣膜置换类型均无显著性差异(P<0.05);两组患者左房直径、房颤病史的长短具有显著性差异(P<0.05),窭性心律组的左房直径、房颤病史均较房颤心律组明显较小、较短。结论 左房直径(<60mm)、房颤病史的长短(<7年)是影响房颤治疗效果的主要因素。更多还原

【Abstract】 Objective To explore the effects of intraoperative radiofrequency ablation of atrial fibrillation duringvalve replacement surgery.Methods January 2010 to December 2013 were completed 100 cases of valvular disease with atrial fibrillation,patients were followed up for 33 months to 6 months,average of(19.8 ± 8.7) months.70 patients maintaining sinus rhythm,30 patients with atrial fibrillation heart again converted.Recalling the two groups of patients left atrial diameter,length history of atrial fibrillation,age,gender,follow-up time,the type of valve replacement.Results There was no significant difference in the patient age,gender,follow-up time,the type of valve replacement between the two groups,(P<0.05);there was significant difference in left atrial diameter,length history of atrial fibrillation between two groups(P<0.05),the left atrial diameter and history of atrial fibrillation in sinus group were significantly smaller than those in atrial fibrillation.Conclusions Left atrial diameter(<60mm) and a history of atrial fibrillation duration(<7 years) are the main factors affecting the treatment of atrial fibrillation.更多还原
