Figure 1 Comparison of Angiographic and IVUS Findings Before and After High-Pressure Stent Post-Dilation

Comparison of angiographic and intravascular ultrasound (IVUS) results after high-pressure stent deployment (A) and after post-dilation with a noncompliant balloon of the same size (B). Note that by angiography, no clear difference can be seen before and after the post-dilation. Conversely IVUS demonstrates a significant increase in lumen cross-sectional area (CSA) after a noncompliant balloon post-dilation.
