Preductal coarctation of the aorta

What it means

Narrowing or constriction of the aorta localized proximal to the ductus arteriosus, i.e., to the preductal region of aortic arch.

Blood flow to the aorta distal to the coarctation may be dependent on a patent ductus arteriosus, and hence closure of the ductus arteriosus can lead to serious ischemia of the affected tissues.
