Diagnosis of anomalous origin of the right subclavian artery (AORSA) from the right pulmonary artery (RPA) is usually made using CT, MRI, or invasive angiography. We report a patient diagnosed using transthoracic echocardiography (TTE). A newborn girl prenatally known to have d-TGA presented with cyanosis sparing the right hemithorax and arm. Oxygen saturations on the right hand were persistently higher than on the right ear and other extremities. Repeat TTE using a modified echocardiographic imaging plane allowed for full visualization of the entire subclavian artery course, revealing AORSA from RPA. We discuss further the approach to echocardiographic diagnosis and surgical implications.
右位主动脉弓（AORSA）异常起源于右肺动脉（RPA）的诊断通常采用 CT、MRI 或有创性血管造影术进行。我们报告了一例使用经胸超声心动图（TTE）诊断的患者。一名新生儿女孩在产前已知患有右旋位 T 型房室连接，表现为右侧胸廓和手臂发绀，右侧手部的氧饱和度持续高于右耳和其他四肢。使用改良的超声心动图成像平面重复 TTE 可全面观察整个锁骨下动脉走行，显示 AORSA 发自 RPA。我们进一步讨论了超声心动图诊断方法和手术影响。
