Abstract

Background: The study objective was to examine the vascular wall changes caused by balloon dilation of coarctation of the aorta (CoA) acutely and at short-term follow-up using intravascular ultrasound imaging. Intravascular ultrasound has been valuable in assessing the vessel wall changes in coronary and peripheral arteries after balloon dilation, often with more detail than angiography. Methods and Results: Intravascular ultrasound imaging, using 4.8F, 20-MHz or 6.2F, 12.5-MHz catheters on either Diasonics or HP scanners, was performed in 17 patients during balloon angioplasty for native (n=12) and recurrent (n=5) CoAs. Nine patients were also studied at the time of follow- up cardiac catheterization 28.1±18.0 months after angioplasty. Immediately after dilation, the mean pressure gradient across the CoA decreased from 42.9±16.4 to 9.0±5.4 mm Hg (P
