摘要
目的:通过封堵前后房间隔缺损患者右心室功能参数的变化,探讨实时三维超声心动图在房间隔缺损封堵中右心功能的监测价值。方法:回顾性分析经临床证实的80例房间隔缺损患者的超声图像,应用QLab软件对比分析封堵前后右室收缩末期容积(RVESV)、舒张末期容积(RVEDV),每搏输出量(RVSV)和整体射血分数(RVEF)。结果:ASD患者封堵后过隔血流消失,右房室内径缩小,三尖瓣反流明显减少或消失,RVESV、RVEDV和RVSV较术前明显减小,RVEF明显增高。结论:RT-3DE可以清晰显示缺损的位置、大小及与周围组织的解剖关系,能满足术前评估ASD的要求,术后RT-3DE能准确评价右室整体及局部容积与收缩功能,为临床早期无创准确评价右室形态功能及指导临床治疗提供有力手段。
Objective To explore the vaule of RT-3 DE in monitoring the right heart function of ASD occluder, by comparing preoperative and postoperative parameter of right heart function. Methods Retrospective analysis the ultrasound image of 80 patients with ASD Confirmed clinically, and use Qlab software to analyze preoperative and postoperative parameter of right heart function. These parameters include right ventricular end-systolic volume(RVESV), end-diastolic volume(RVEDV), stroke volume(RVSV) and ejection fraction(RVEF). Result After ASD occlusion, the separated flow disappear, the interior diameter of right atrium and right ventricular become smaller, tricuspid regurgitation is reduced significantly or disappeared. RVESV, RVEDV and RVSV are decreased significantly before the operation. RVEF is increased obviously. Conclusion RT-3 DE can show us the location, size, and the relationship with surrounding tissue of the defect, to meet the requirements of preoperative evaluation of ASD. Using RT-3 DE postoperative can accurately evaluate the whole or local volume and systolic function of right ventricular. RT-3 DE. RT-3 DE can provide a noninvasive and accurate assessment of the right heart function in those ASD, and it can help to guide clinical treatment.
