Balloon Angioplasty of Subatretic Coarctation of the Aorta Using Progressive Larger Balloons

José Luiz Balthazar Jacob and Dárcio Gitti de Faria

We report a case of subatretic coarctation of the aorta with dilated ascending aorta in a three-year-old boy weighing 14 Kg. Surgical treatment was indicated, but it was refused. Balloon angioplasty of the coarctation was performed using progressive increase in the diameter of the balloons. The diameters of the balloons ranged from 2 to 10 mm, and the gradient decreased from 60 down to 12 mmHg. We conclude that the balloon angioplasty with careful progressive increase in the balloon diameter is safe in the treatment of subatretic coarctation of the aorta with good results.
