Abstract：
Persistent fifth aortic arch is a rare congenital anomaly that can be discovered incidentally or at postmortem exam. It can be associated with major congenital heart malformations involving the systemic or the pulmonary circuits. It usually has no clinical significance but can be either, beneficial as in systemic outflow tract obstructions or cause hemodynamic compromise when associated with a significant left to right shunt. We report an infant with persistent fifth aortic arch associated with Shone\'s complex diagnosed accurately by transthoracic echocardiography and confirmed by cardiac catheterization and computed tomography.
