Abstract
We report a case of prenatally diagnosed isolated right aortic arch (RAA) and describe the procedure for its ultrasound-guided diagnosis and clinical management. The ultrasound scan of a 20-week-old fetus revealed an isolated RAA. The diagnosis was achieved using the 3 vessels and trachea view, in which the aortic arch was visualized to the right side of the trachea. RAA is a rare finding (incidence, 0.1%) and its variants may cause compressive symptoms and be associated with congenital heart defects (up to 90%) and/or 22q11 microdeletion (up to 46%). The 3 vessels and trachea view is essential for the prenatal diagnosis of RAA. Detection of this condition must be considered an indication for fetal echocardiography, to distinguish its variants, and a genetic study is also recommended. Isolated RAA is usually asymptomatic, although the outcome of RAA associated with other abnormalities is uncertain.
