In the early days of transesophageal echocardiography, the "Q-tip sign" was occasionally mistaken for a left atrial mass. This area is now well recognized as a normal anatomic landmark dividing the left atrial appendage from the left upper pulmonary vein. However, in this report we describe 2 patients in whom pathology was found in this area, which should not be overlooked.
在经食管超声心动图早期，“棉签征”偶尔会被误诊为左心房肿块。现在这个区域已被公认为是将左心耳与左上肺静脉分开的正常解剖标志。然而，在本报告中，我们描述了2例在该区域发现病变的患者，这一情况不应被忽视。
