Successful outcome was defined as peak systolic pressure gradient \u226420 mmHg after stent implantation.

Peak systolic pressure gradient decreased from mean 62.4\u2009\u00b1\u200918 mmHg (range 35\u2013100 mmHg) to mean 2.8\u2009\u00b1\u20095 mmHg (range 0\u201315 mmHg; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Stent displacement occurred in 3 patients during the procedure. These were managed successfully by an overlapping second stent. None of the patients had major complications such as aortic dissection, rupture, or vascular access problems. In follow up, only three patients had recoarctation, and two of these were managed successfully by balloon redilation or further stenting 16 and 18 months after the first procedure and one patient refused reintervention. There were two deaths, unrelated to the procedure, 12 and 78 months after the initial intervention. Follow\u2010up of a mean of 45.5\u2009\u00b1\u200917 months (range 12\u2013105 months) demonstrated no evidence of aneurysm formation or stent
