Abstract. Two patients who had a balloon angioplasty for native coarctation of the aorta as neonates underwent redilatation for restenosis 1 or 2 months after the initial procedure. We recorded intravascular ultrasound (IVUS) images at redilatation. Before redilatation, there was an abnormal, localized area of ultrasound density equal to the inner layer of the aorta. The enlargement of this tissue was in proportion to the severity of stenosis and diminished after dilatations. No intimal flaps or tears were observed. From the IVUS images it appears that the mechanism to relieve the coarctation of our patients may be compression of this abnormal tissue.
