交叉心超声心动图回顾性分析

Retrospective analysis of echocardiography on criss-cross heart

目的对交叉心超声心动图特征进行总结，探讨超声心动图对此疾病的诊断价值。方法回顾性分析10例确诊交叉心患者二维、彩色多普勒超声心动图特征，对其诊断要点及诊断方法进行总结。结果10患者中9例右心室及左心室呈上下排列，1例呈并列排列。房室及动脉连接关系9例为心房正位，8例房室连接关系一致，5例患者伴有完全性大动脉转位，5例伴有右室双出口，所有患者均伴有室间隔缺损。结论超声心动图能够清晰显示房室瓣水平呈“十字交叉”体肺静脉血流轴以及异常位置的室间隔，对明确交叉心诊断及伴发畸形具有重要诊断价值。

Objective To describe the characteristics of the criss-cross heart with comprehensively segmental echocardiographic scanning in order to explore the diagnostic value of the echocardiography. Methods Ten cases of criss-cross heart were retrospectively reviewed with 2-dimensional,color Doppler echocardiography to summarize the main diagnostic methods, Results The right ventricle was located superiorly and the left ventricle inferiorly in 9 patients and paralleled alignment in 1. The solitus situs was observed in 9 patients and dextrocardia in 1 ;the atrioventricular connections were concordant in 8 patients and discordant in 2, Echocardiography revealed that 5 patients presented with transposition of great artery and 5 with double outlet of right ventricle as well as all with ventricular septum defect, Conclusions Clear visualization is available with echocardiography to show the crossing inflow streams at the level of atrial-ventricular valve, abnormal alignment of the ventricular septum as well as the associated abnormalities.
