摘要

目的：探寻孤立性单心房（ISA）彩色多普勒超声心动图（CDE）图像特征及规律性。方法：应用CDE检查30例ISA，寻找ISA的CDE图像特征及规律性，14例经心血管造影对照，所有病例均经手术证实。结果：根据CDE图像特征对27例ISA做出正确诊断，诊断准确率90.0％，另外3例误诊为部分房室隔缺损。ISA的CDE图像特征及规律性明显：①二维超声心动图（2DE）胸骨旁左室长轴切面显示右心室内径增大，左心室流出道变窄延长。心尖四腔心切面显示房间隔回声全部失落，收缩期二、三尖瓣关闭，正常心内“十字交叉”图像消失，呈“倒T形”改变。胸骨旁二尖瓣水平心室短轴切面显示二尖瓣前叶呈“断桥样”改变。②M型超声显示室间隔与左室后壁呈同向运动，左室流出道内径变窄，二尖瓣前叶呈双曲线回声。③连续多普勒估测肺动脉压力均大于30mmHg。④彩色多普勒血流显像于收缩期显示过二、三尖瓣五彩镶嵌反流束血流信号，于舒张期显示过肺动脉瓣五彩镶嵌反流束血流信号。结论：ISA的CDE图像特征及规律性明显，CDE对ISA有特异性诊断价值，但需要与部分房室隔缺损鉴别诊断。

Abstract

Objective: To investigate the imaging character and regularity of isolated single atrium(ISA) in color Doppler echocardiography(CDE). Methods: Thirty patients of ISA were examined with CDE. Fourteen cases of them underwent angiocardiography for correlation. All of the cases were confirmed by operation. Results: Twenty-seven cases were accurately diagnosed by CDE image with the diagnostic accuracy rate of 90.0%. The other 3 cases were misdiagnosed as partial atrioventricular septal defect. The features of CDE image in ISA had obvious characteristics: ①The parasternal long-axis view of left ventricle by 2DE showed an enlarged right ventricle and elongation and narrowing of the left ventricle outflow tract. The apical four-chamber view showed echo dropout in the interatrial septum, closure of the mitral and tricuspid valve during systole and the substitution of normal “cross” image by a “upside-down T” sign. Parasternal short axis view at the mitral valve level in 2DE showed a “broken bridge”-like anterior mitral leaflet. ②M-mode ECG showed equidirectional movement of the interventricular septum and the posterior left ventricular wall, narrowing of the outflow tract of left ventricule and a double-curve echo of the anterior leaflet of mitral valve. ③Continuous-wave Doppler assessments of pulmonary artery pressure were more than 30mmHg in all the cases. ④Color Doppler flow imaging showed colorful regurgitation flow through the mitral valve and the tricuspid valve during systole and through the pulmonary valve during diastole. Conclusions: The feature of CDE image in ISA is obvious and is valuable in diagnosis for ISA, but it should be differentiated from partial atrioventricular septal defect.
