背景资料：本研究的目的是评估AV瓣膜形态的准确性评估实时经胸三维超声心动图（RT-3DE）相比，手术结果和评估RT-3DE是否适用于临床practice.Methods：2004年6月至2005年5月，19例房室间隔缺损（AVSD）在我们的机构接受手术治疗的患者参加了这项研究。RT-3DE采用Philips Sonos 7500超声系统，TomTec Echoview（c）软件进行离线分析。评估了AVSD的AV瓣膜形态，特别关注上级和下级桥接瓣叶。3D数据进行了比较，在手术proceeding.Results：RT-3DE数据集的采集过程中获得的测量和描述是可行的，在所有患者。19例患者中有11例婴儿（年龄< 1岁）。3D数据采集的持续时间为12 - 3分钟以上的患者1岁和4 +/- 2的婴儿。所有患者的AV瓣口和上级、下桥瓣的RT-3DE观察结果与手术结果相比均正确。结论：实时经胸三维超声心动图能准确评价AVSD，并能正确显示AV瓣的形态。经过短暂的学习曲线，RT-3DE很容易应用于日常临床实践。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
Background: The purpose of this study was to evaluate the accuracy of AV valve morphology assessed by real-time transthoracic 3D echocardiography (RT-3DE) compared to surgical findings and to assess whether RT-3DE is applicable in clinical practice.Methods: Between June 2004 to May 2005, 19 patients with an atrioventricular septal defect (AVSD) undergoing surgical treatment at our institution were enrolled in the study. RT-3DE was performed with Philips Sonos 7500 echo-system and off-line analysis with TomTec Echoview (c) software. The AVSD was assessed for the morphology of AV valve, with particular interest to the superior and inferior bridging leaflets. 3D data were compared with measurements and descriptions acquired during the surgical procedure.Results: Acquisition of RT-3DE datasets was feasible in all patients. Of the 19 patients, there were I I infants (age < 1 year). The duration of 3D data acquisition was 12 3 min for patients above I year and 4 +/- 2 for infants. Reconstruction time was 22 8 min. In all patients the AV valve orifice and RT-3DE observations of the superior and inferior bridging leaflets were all correctly identified by RT-3DE compared with the surgical findings.Conclusion: Real-time transthoracic 3D echocardiography provides accurate assessment of AVSDs and correctly depicts the AV valve morphology. After a short learning curve, RT-3DE is easily applicable during daily clinical practice. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
