Abstract

Intracoronary imaging devices, intravascular ultrasound (IVUS) and optical coherence tomography (OCT), have been applied to percutaneous coronary intervention (PCI) for several decades. Through vigorous research on ischemic heart diseases, IVUS and OCT have been established as useful devices for PCI. In addition, vulnerable plaques detected by those devices have been consistently associated with the increased risk of major adverse cardiac events. However, there are still limitations on IVUS and OCT, including a low positive value for the prediction of future events, intrinsic limits arising from characteristics of ultrasound and light, and the low rate of usage in daily clinical practice. To overcome those issues, various efforts are still in progress. In this review, we describe the history, current status and future directions of intracoronary imaging devices.
