摘　　要：目的探讨实时三维超声心动图(RT-3DE)技术评价房间隔缺损(ASD)的可行性和临床价值;评价RT-3DE测值和手术的相关性;记录房间隔缺损在心动周期中的动态变化及影响因素。方法收集2010年6月至2012年1月我院心脏外科行外科手术治疗的房间隔缺损患者32例,应用Philips iE33行RT-3DE成像,Qlab工作站载机和脱机分析。分别将二维、三维测值与手术测值行相关分析。结果 93%的患者可以获得RT-3DE数据。RT-3DE测得的缺损大小与手术的相关性优于二维(r分别为0.97和0.92,P<0.05)。ASD在心动周期中呈现动态变化,收缩末期最大,舒张末期最小。结论 RT-3DE可为先天性心脏病提供更多的空间信息,进行缺损部位、大小、数目、毗邻结构的确切评价。Objective To explore the feasibility and clinical significance of real-time three-dimensional echocardiography （RT-3DE） in as- sessing atrial septal defect, to investigate the reliability of RT-3DE findings compared with operation, to record dynamic changes of atrial sep- tal defect （ASD） during a cardiac cycle and analyze the risk factors which influence ASD. Methods From June 2010 to Jan 2012,32 pa- tients with ASD undergoing surgical treatment at our institution were eurolled in the study. RT-3DE was performed with Phifips iE33 and off- line analysis with QLab work-station. 3D data were compared with measurements and descriptions by 2-dimentional echocardiography and sur- gical findings. Results Acquisition of RT-3DE data was feasible in 93% of patients. The sizes obtained from RT-3DE showed better cor- rection with surgical findings than measurement by 2D eehocardiography （r =0.96 vs r =0.92）. The ASD area showed dynamic changes dur- ing the cardiac cycle with an end-systolic maximum and end-dia,stohc minimum. There was no con＇elation between the relative change and ASD size or heart rate. Conclusion RT-3DE provides more spacial information in congenital heart disease, and otters accurate assessment of septal defect location, size, numbers, and surrounding structures. With a short learning curve, RT-3DE is easily applic＇able during daily clinical practice.
