An exceedingly rare cause of neonatal shock: persistent fifth aortic arch with critical coarctation

We present a case of a 13-day-old neonate with shock who was diagnosed with persistent fifth aortic with critical coarctation by cardiac point-of-care ultrasound and surgery confirmed the anomalies. This case demonstrates the value of cardiac point-of-care ultrasound in detecting congenital anomalies of great vessels in neonates and may be beneficial in clinical management.
