This report describes the 2-dimensional (2-D) echocardiographic appearance of left-sided juxtaposition of the atrial appendages (JAA). From January 1, 1978, to June 30, 1979, 2 infants had the diagnosis of left-sided JAA at autopsy. Both patients had previously been examined by subxiphoid 2-D echocardiography. On review of these studies, the septum secundum was found to be oriented posteriorly in the transverse view of the atria. From July 1979 to June 1981, prospective evaluation of all infants for the presence of this finding revealed 2 more patients. Left-sided JAA was confirmed at surgery in 1 case and by selective right atrial angiography in the other. The diagnosis of left-sided JAA has important implications for both atrial baffle operations and for the Fontan procedure.
本报告描述了左侧心耳并列（JAA）的二维（2-D）超声心动图表现。1978年1月1日至1979年6月30日期间，有2名婴儿在尸检时被诊断为左侧JAA。这两名患者此前均接受过剑突下二维超声心动图检查。回顾这些研究发现，在心房的横向视图中，房间隔呈向后的方向。1979年7月至1981年6月，对所有婴儿进行前瞻性评估以确定是否存在这一发现，又发现了2例患者。其中1例在手术中确诊为左侧JAA，另一例通过选择性右心房血管造影确诊。左侧JAA的诊断对心房挡板手术和Fontan手术均具有重要意义。
