Left juxtaposition of the atrial appendages is usually associated with cyanotic congenital heart disease. Recognition of this rare anomaly is important before therapeutic or surgical procedures that involve the atrial septum can be undertaken (for example, septostomy, the Mustard or Senning operation and the Fontan anastomosis). The diagnosis of left juxtaposition of the atrial appendages is most commonly an incidental finding at the time of surgery or autopsy. This report describes the two-dimensional echocardiographic visualization of left juxtaposed atrial appendages. The diagnostic echocardiographic features are based on characteristic alterations of the plane of the atrial septum and visualization of the malpositioned right atrial appendage. On the basis of these observations, a noninvasive diagnosis of left juxtaposed atrial appendages is now possible by means of two-dimensional echocardiography.
左心耳并列通常与青紫型先天性心脏病相关。在进行涉及房间隔的治疗或手术操作（例如，房间隔造口术、Mustard或Senning手术以及Fontan吻合术）之前，认识到这种罕见的异常情况很重要。左心耳并列的诊断最常见的是在手术或尸检时偶然发现。本报告描述了左心耳并列的二维超声心动图表现。诊断性超声心动图特征基于房间隔平面的特征性改变以及位置异常的右心耳的可视化。基于这些观察结果，现在可以通过二维超声心动图对左心耳并列进行无创诊断。
