Figure 1 Aortic Arch Measurements
Aortic arch width (W) corresponds to the transverse diameter of the arch and is defined as the maximal transverse distance between the midpoints of the ascending and descending aorta, close to the axial plane going through the right pulmonary artery. Height of the aortic arch (H) is defined as the maximal vertical distance between W and the highest mid-point of the aortic arch.  m is the minimal diameter at the coarctectomy site, and D is the diameter of the descending aorta.
