    Intravascular Ultrasound in Endovascular Interventions for Peripheral Artery Disease

    The evidence supporting IVUS use for endovascular interventions is mostly driven from retrospective observational studies. IVUS use for endovascular interventions is controversial given the availability of other less expensive imaging …

  13. Integrated backscatter-intravascular ultrasound and modification of plaque during excimer laser coronary angioplasty

    This study aims to test the hypothesis that the effect of excimer laser coronary angioplasty (ELCA) not only vaporizes thrombi and their underlying coronary plaque, it also changes their quality. We performed a series of cross-sectional analyses …
