Three-dimensional reconstruction of the arch anatomy of patient 7, the most
common arch we encountered. Panel A is right posterior oblique view and
panel B is left posterior oblique. Both views show the coarctation (Coarct)
and ascending aorta (AAo), with the descending aorta (DAo) seen well in
panel A. In panel B, the left subclavian artery (LSCA) is shown arising from
a retroesophageal (Kommerell’s) diverticulum. In this same
panel, the trachea is green, the esophagus is yellow, and the pulmonary
artery (PA) is purple.
