You have to realize, that axial CT-images are viewed from the feet, while the illustrations above are viewed from above On the axial image there is a right arch Coattacion the volume rendered image there is mirror image branching of the brachiocephalic arteries, no aberrant subclavian artery, so this is a right arch mirror image. Depending on the severity of the patient’s condition, which is coartqcion on a case-by-case level, visiting a cardiologist can be a once a year or less frequently surveillance check up.
