Abstract

Percutaneous coronary intervention (PCI) is the standard treatment for coronary artery disease. To achieve successful stent implantation, various intravascular imaging modalities, such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT), have been widely used during PCI. However, IVUS and OCT have several advantages and disadvantages, which have led to the need for the development of another imaging technique. Recently, near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS) was introduced as a novel intravascular imaging modality that can provide additional information and overcome each of the shortcomings of IVUS and OCT. Therefore, the aim of this manuscript is to outline NIRS-IVUS as a method that can detect, specify, and quantify the presence of a lipid-core in the atherosclerotic plaque and to review its clinical applications based on recent studies.
