Abstract
Coronary intravascular imaging (Intravascular Ultrasound and Optical Coherence Tomography) and assessment of intracoronary physiological function (Fractional Flow Reserve) have great potentials to be exploited, but the low utility rate, the poor interpretation of intravascular imaging, and a lack of personal skills of intravascular imaging in medical practice are still posing significant challenges, especially in underdeveloped countries. This review is to offer a general overview and recent evidence that indicates intracoronary imaging and physiological function are potential tools for the optimization of percutaneous coronary intervention from diagnostic, therapeutic, and prognostic perspective. Moreover, the role of coronary intravascular imaging played in identifying atherosclerotic plaque formation or calcium lesion will be discussed. Meanwhile, several possible solutions to relatively limited clinical use of coronary intravascular methods will be discussed. Future perspectives for a novel way of thinking in terms of a combination of artificial intelligence and coronary intravascular imaging (anatomical evaluation) and/or physiological function (ischaemic evaluation) to guide operators in making final stent implantation strategy are also discussed. This review provides a reference for present intracoronary technical characteristics and clinical application, especially for those who are beginners to learn the field regarding coronary intravascular imaging, focusing on the perspective of clinical practice along with technical profile, but not from the technical level.
