CoA/DAo ratio = the ratio of the coarctation diameter to the descending aorta diameter measured at the level of the diaphragm; CoA Pre = diameter at coarctation site before stent; CoA Post = diameter of CoA after stent; Mean gradient Pre = mean systolic gradient before stent; Mean gradient Post = mean systolic gradient after stent.
