The inferior cavoatrial junction (ICAJ) is the term given to the point at which the inferior vena cava (IVC) enters the right atrium. It is less commonly used/seen, in contradistinction to the superior cavoatrial junction.
Accurate localization of the inferior cavoatrial junction is of practical importance in neonates/infants when it comes to correct placement of peripherally inserted central catheter (PICCs), which have been inserted via a lower limb vein.
