We found that echocardiography in cases of left juxtaposed atrial appendage (JAA) consistently featured a malpositioned right atrial appendage, abnormal spatial orientation of the atrial septum, and posterior deviation of the septum secundum toward the left atrium. The qualitative displacement of the septum secundum together with the posterior and leftward displacement of the right atrial appendage (with respect to the great arteries) prompted us to pose questions concerning the morphogenesis of left JAA and the implications for surgery. The importance of precatheterization and preoperative recognition of left JAA in dextrotransposition of the great arteries by echocardiography cannot be overemphasized when planning a balloon atrial septostomy or a biventricular repair.
我们发现，在左并列心耳（JAA）病例中，超声心动图始终显示右心耳位置异常、房间隔空间方位异常以及继发隔向后向左心房偏移。继发隔的定性移位以及右心耳（相对于大动脉）向后和向左移位促使我们对左JAA的形态发生及其对手术的影响提出疑问。在计划球囊房间隔造口术或双心室修复时，超声心动图对大动脉右转位患者术前识别左JAA的重要性再怎么强调也不为过。
