Aortic isthmus
Updates to Article Attributes
Body
was changed:
The aortic isthmus is the part of the aortic arch just distal to the origin of the left subclavian artery at the site of the ductus arteriosus.
This portion of the aorta is partly constricted in the fetus because of the lack of flow within the aortic sac and ascending aorta. It marks the partial separation of fetal blood flow derived from the right and left ventricles.
