1·In case 6, the heart looks "inverted" compared to normal (Figure 8). This phenomenon is called dextrocardia, and it results from a looping anomaly during embryologic development.
病例6中的心脏与正常相比看上去就像“反转”了一样(图8)，这称作右位心，是由于胚胎发育过程中的心脏成环异常导致。
2·Results Eleven cases (11/12) of fetal cardiac malposition were detected by fetal echocardiography, including dextrocardia, sinistrocardia, extrathorax heart and common heart of conjoined twins.
结果超声检出胎儿心脏位置异常11例（11 /12），包括右位心、左旋心、胸外心脏、连体双胎共同心脏等类型。
3·The third cardiac malposition is dextrocardia.
第三种心脏位置异常是右位心。
4·Objective: To evaluate the clinical utility of echocardiography in the diagnosis of dextrocardia and concomitant cardiovascular malformations.
目的：探讨超声心动图对右位心及其伴随的心血管畸形的诊断价值。
