超声心动图是诊断婴幼儿先天性心脏病最常用的非创伤性影像检查技术。缺点之一是需大量心脏切面图像才能在检查者头脑中建立起完整的心脏三维结构。这可能导致对心脏缺陷解剖学诊断的不完整或错误。三维图像重建可提高超声心动图诊断的准确性。作者报道应用计算机断层成像探头对婴幼儿进行经胸动态三维超声心动图检查的初步经验。 45例患儿(出生后3天～17岁),包括:室间隔缺损11例,主动脉瓣下狭窄9例,房室隔缺损7例,房间隔缺损4例,右室双出口3例,大动脉转位3例,主动脉狭窄2例,Ebstein’s畸形2例,永存动脉
Echocardiography is the most common noninvasive imaging technique used to diagnose congenital heart disease in infants and young children. One of the drawbacks is that a large number of heart-cut images are needed to establish a complete three-dimensional structure of the heart in the examiner’s mind. This may result in incomplete or incorrect diagnosis of cardiac defect anatomy. Three-dimensional image reconstruction can improve the diagnostic accuracy of echocardiography. The authors report a preliminary experience with thoracic dynamic three-dimensional echocardiography using computed tomography probes in infants and young children. 45 children (3 days to 17 years old), including 11 cases of ventricular septal defect, 9 cases of aortic valve stenosis, 7 cases of atrioventricular septal defect, 4 cases of atrial septal defect and 3 cases of right ventricular double outlet, Transposition of the great arteries in 3 cases, 2 cases of aortic stenosis, Ebstein’s malformation in 2 cases, permanent artery
