[Clinical and magnetic resonance imaging follow-ups of children after dilatation of aortic isthmus stenosis (CoA)].

Aortic aneurysm and stenosis are the most severe post-interventional complications after angioplasty of CoA and require regular follow-up. Twenty children (4 2/12-13 11/12 years old) underwent MRI within 3 months to 5 7/12 years after dilatation. All children were in a good state of health and showed no signs of heart failure.
