(2)术后3d与术前相比,LAVmax、LAVmin、LAEF差异无统计学意义,SRs、SRe、SRa减小.(3)术后6个月与术后3d相比,LAVmax、LAVmin减小,LAEF及SRe、SRa、SRs增大.(4)术后6个月与对照组比较,LAVmax、LAVmin、LAEF、左房前壁、房间隔、下壁SRe、SRa、SRs差异无统计学意义,左房侧壁、后壁SRe、SRa、SRs减小.结论 射频消融术后短时间内,处于左房功能顿抑期;术后6个月,左房结构和功能逐渐恢复.RT-3DE及STI对评价消融术前后左房重构有重要价值.%Objective To study the clinical value of real-time three-dimensional echocardiography (RT-3DE) and speckle tracking imaging (STI) in evaluating structure and functional remodeling of left atrium for patients with atrial fibrillation before and after radiofrequency ablation.Methods Thirty three patients with paroxysmal atrial fibrillation before ablation,3 days and 6 months after ablation and 25 healthy volunteers were examined respectively by echocardiography.Simultaneously,the left atrial maximal volume (LAVmax),left atrial minimal volume (LAVmin),left atrial ejection fraction (LAEF) were measured by RT-3DE,then the left ventricular peak systolic strain rate (SRs),left ventricular early diastolic strain rate (SRe),left atrial peak systolic strain rate (SRa) were measured by STI.Results (1) Compared with the control group,preoperative LAVmax,LAVmin increased,LAEF,SRs,SRe,SRa decreased in the patients.(2) With respecting to the preoperative status,the differences of LAVmax,LAVmin,LAEF were not statistical,but SRs,SRe,SRa decreased in the group 3 days after ablation.(3)Six months after ablation,LAVmax,LAVmin decreased and LAEF,SRe,SRa,SRs increased compared with the 3 days after ablation in these patients.(4)In the group of 6 months after ablation,the difference of LAVmax,LAVmin,LAEF,SRe,SRa,SRs of anterior wall of the left atrium,atrial septum,inferior wall were not statistical,but SRe,SRa,SRs of Left atrial side wall,left atrial inferior wall decreased being compared with the control group.Conclusions In a short time after radiofrequency,left atrial function of the patients were in a stunning period.Six months later,the left atrial structure and function gradually recovered.RT-3DE and STI had an important value in evaluating left atrial remodeling before and after radiofrequency ablation. 【总页数】4页(P118-121) 【作 者】汪婧;江峰;刘表虎;朱菲菲;王嶒 【作者单位】241001 安徽省芜湖市,芜湖皖南医学院弋矶山医院超声医学科;241001 安徽省芜湖市,芜湖皖南医学院弋矶山医院超声医学科;241001 安徽省芜湖市,芜湖皖南医学院弋矶山医院超声医学科;241001 安徽省芜湖市,芜湖皖南医学院弋矶山医院超声医学科;浙江省人民医院超声医学科 【正文语种】中 文 【相关文献】 1.斑点追踪显像技术评价急性心肌梗死患者左房功能的临床价值2.实时三维超声联合斑点追踪超声评价阵发性房颤患者射频消融术后左室同步性及收缩功能3.二维斑点追踪成像技术评价阵发性房颤患者射频消融术前后左心房功能4.实时三维超声心动图评价心房颤动患者射频消融术前后左心房功能及二尖瓣构型的变化5.实时三维超声心动图联合二维斑点追踪显像技术评价冠状动脉慢血流患者左房结构及相位功能改变 因版权原因，仅展示原文概要，查看原文内容请购买 本文来源：https://www.wddqw.com/doc/00a4d546a9ea998fcc22bcd126fff705cc175c8d.html
