Persistent left fifth aortic arch in a child without congenital heart disease: Echocardiographic and magnetic imaging correlation

Persistence of the left fifth aortic arch is rare. The first reported case was by Van Praagh et al and since then, there have been about 16 additional case reports. All of these cases had associated cardiac lesions such as tricuspid atresia, ventricular septal defect, transposition of the great arteries, coarctation of the aorta, pulmonary atresia, or patent ductus arteriosus. The purpose of this report is to document the presence of a left fifth arch in a patient without structural cardiac disease.
