The first section of this article reviews how intracoronary ultrasound (ICUS) has been used to identify the mechanisms of action of directional coronary atherectomy (DCA) and examines the influence of plaque composition and morphology on DCA outcomes. The process of restenosis is then described. Results from trials using ICUS-guided DCA are evaluated, demonstrating how the information obtained from ICUS is being used to improve the angiographic and clinical outcomes of directional atherectomy. Finally, data are incorporated to provide practical applications for the use of DCA.
