Results of balloon angioplasty (29 patients, age 15\u201371 years, during 1995\u20132005) for discrete, native coarctation were evaluated, including MRI or CT.<jats:styled-content>Results:<\/jats:styled-content>Mean follow\u2010up ranged from 2.2 to 13 years (mean 8.5 \u00b1 3.2). Immediate success was obtained in all patients. Early mortality or complications were not encountered. Peak systolic pressure gradient decreased from 52 \u00b1 21 to 7.2 \u00b1 7.6 mm Hg (<jats:italic>P<\/jats:italic>&lt; 0.001). Intima tear was detected in eight procedures angiographically, without signs of dissection. Three\u2010month follow\u2010up angiography in these patients showed unchanged (4\/8 patients) or diminished abnormalities (4\/8 patients). One asymptomatic patient, known with left ventricular dysfunction due to significant aortic valve insufficiency, died suddenly 5 years after balloon angioplasty. Recoarctation occurred in one patient (3%). Late aneurysm formation was excluded by MR in 24\/29 and CT in remaining 5\/29 patients during follow\u2010up, including those patients in whom intima tear was encountered immediately postangioplasty. In three of seven patients an irregular aortic contour persisted, without indication of progression or aneurysm formation. Hypertension was completely relieved in 67% (14\/21 patients) and improved in 33% (7\/21 patients).<jats:styled-content>Conclusions:<\/jats:styled-content>Balloon angioplasty for native coarctation yields low reintervention probability in adult patients. Despite occurrence of angiographically established intimal tearing, aortic dissection and aneurysm formation were not encountered. \u00a9 2009 Wiley\u2010Liss,
