It is valid to dilate native aortic coarctation with a balloon catheter.

We report our experience in 37 patients with aortic coarctation who underwent balloon aortoplasty. Of the 37, the lesion was native in 34 cases. Clinical re-evaluation was possible in 22 patients, with a mean follow-up period of 13 months and, of these, 21 patients were asymptomatic. Haemodynamic and angiographic studies were performed in 13 patients, with a mean period of follow-up of 12 months, showing excellent results in 11 patients. Aneurysmal formation had occurred in one and recoarctation in the other patient. Our experience has proved that balloon aortoplasty is an effective method for treating patients with aortic coarctation. Adequate selection in terms of the morphology of the coarctation and the size of the balloon catheter are crucial factors in the success of the procedure.
