Left juxtaposition of the right atrial appendage (RAA) is a rare congenital cardiac malformation, where both atrial appendages are located leftward of the great arteries. Despite well-described echocardiographic markers, this diagnosis remains challenging to establish, especially for the novice imager. We describe the in three patients with juxtaposed RAA. We noted that the normal left atrial appendage was visualized from the apical four-chamber or equivalent coronal view at the level of the atrioventricular valves.
右心耳(left atrial appendage, RAA)左侧并列是一种罕见的先天性心脏畸形，即两个心耳均位于大动脉左侧。尽管超声心动图有明确的标记物，但对于初学者来说，这种诊断仍然具有挑战性。我们在三名并列 RAA 患者中描述了这一征象。我们注意到，正常的左心耳可以在房室瓣水平的心尖四腔心或相应的冠状切面从心尖部显示。
