摘要
目的:应用实时三维超声心动图对微创外科治疗持续性心房颤动(房颤)术前及术后左心房功能进行定量评价,探讨其规律性。方法:选取2009年12月至2011年01月期间在我院进行微创外科治疗的持续性房颤患者50例,分别于微创外科治疗的持续性房颤术前、术后1个月、3个月及6个月行实时三维超声心动图检查测量左心房舒张末期容积(LAVmax)、收缩末期容积(LAVmin)、射血分数(LAEF)。同时计算左心房管道功能的心房被动射血分数(LAEFpassive)及左心房泵功能的心房主动射血分数(LAEFactive)。结果:微创外科治疗持续性房颤患者术后LAVmax,LAVmin随着随诊时间的增加而逐渐减小(P<0.05)。术后LAEF、LAEFpassive、LAEFactive随着随诊时间的增加而逐渐增大(P<0.05)。结论:实时三维超声心动图可以对微创外科治疗持续性房颤患者的左心房功能,进行定量评价。
Objective:This aim is to quantitative evaluate the left atrium function of preoperative and postoperative minimally invasive surgical treatment of atrial fibrillation by real-time three dimensional echocardiography,to discuss its regularity.Methods:From December 2009 to January 2011,50 patients with surgical treatment of atrial fibrillation.The subjects were examined by three dimensional echocardiography during preoperative surgical treatment,postoperative surgical treatment 1 month,postoperative surgical treatment 3 month,postoperative surgical treatment 6 month.The left atrial end-diastole volume(LAVmax),left atrial end-systolic volume(LAVmin),left atrial eject fraction(LAEF),left atrial passive eject fraction(LAEFpassive) and left atrial active eject fraction(LAEFactive) were measured.Results:The LAVmax,LAVmin was significantly decreased in postperative surgical treatment of atrial fibrillation than preoperative surgical treatment of atrial fibrillation(P0.05).The LAEF,LAEFpassive,LAEFactive was significantly increased in postperative surgical treatment of atrial fibrillation than preoperative surgical treatment of atrial fibrillation(P0.05).Conclusion:The left atrial function in patients with surgical treatment of atrial fibrillation was increased by time,it can be quantitative evaluate by three dimensional echocardiography.
