Infant with congenital diaphragmatic hernia on arterial-venous ECMO

CXR of arterial-venous extracorporeal membrane oxygenation (ECMO)
CXR shows normal position of the arterial catheter tip in the aortic arch and abnormal position of the venous catheter tip (represented by a radio-opaque point) in the superior vena cava. Further advancement of the tip into the right atrium is necessary.

The diagnosis was abnormal position of the venous ECMO catheter tip.
