The distance (LCCA-IA) had a range of Zero (common origin) to 22.3 mm. The distance ratio (LCCA-IA)\/(LSCA-IA) ranged between Zero and 89%. Group I had a significantly higher incidence of adverse outcomes, including recoarctation, re-elevation of blood pressure, and re-elevation of pressure gradient, compared to Group II (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.0001, 0.011, and 0.014, respectively).
