Abstract:
Double aortic arch with an atretic left aortic arch can resemble like a right aortic arch with an aberrant left subclavian artery or a right aortic arch with mirror image branching. Differentiating these closely resembling fetal aortic arch abnormalities is important for proper prenatal counselling and immediate neonatal evaluation. In this pictorial essay, we describe these three cases and its typical imaging features using conventional and four-dimensional echocardiography.
