先天性心脏位置异常包括镜象右位心、孤立性右位心、孤立性左位心及中位心。有先天性心脏位置异常者并不一定有心内结构异常,相当一部分的镜象右位心及中位者心内结构完全正常。但先天性心脏位置异常者如伴有心内缺损,其平片分析方法与心脏位置正常者略有不同,本文通过回顾我院经心血管造影证实的有心内结构异常的先天性心脏位置异常病例,讨论如何通过X线平片对其心内畸形作出较准确的诊断。 Abnormalities in congenital heart location include mirror right centroid, isolated right centroid, isolated left centroid and central centroid. Patients with congenital cardiac abnormalities do not necessarily have intracardiac structural abnormalities, and a significant portion of the right and left central structures are perfectly normal. However, patients with congenital heart abnormalities, such as associated with intracardiac defects, plain film analysis method and the normal cardiac position are slightly different from this review by our hospital confirmed by cardiovascular angiocardiography congenital heart abnormalities in congenital heart disease cases, Discuss how to make a more accurate diagnosis of intracardiac malformations by plain radiography.
