- Discrete stenosis of the upper thoracic aorta, usually just opposite the site of insertion of the ductus arteriosus (juxtaductal). A segment of tubular hypoplasia and/or a remnant of ductal tissue gives rise to a prominent posterior infolding (“the posterior shelf”).
- The hemodynamic lesion is most often discrete, but may be long segment or tortuous in nature. It is usually juxtaductal but may occur in other sites (i.e., the abdominal aorta). The prevalence of other associations (bicuspid aortic valve) and long-term complications (hypertension) indicate the possibility that this lesion is part of a broader spectrum arteriopathy and/or endothelial disorder.
