Intracoronary Imaging Assessment of Stent Thrombosis

Abstract

Abstract Purpose of Review This review focuses on the benefits, limitations, and evidence regarding the use of various intravascular imaging modalities in evaluating the etiology of stent thrombosis (ST). Recent Findings Intravascular ultrasound and optical coherence tomography can be used clinically to evaluate the etiology of ST including malapposition, underexpansion, stent fracture, and neoatherosclerosis. Near-infrared fluorescence has also been shown to have niche benefits in ST due to abnormal stent endothelization. Additionally, intravascular imaging also helps guide intervention depending on the etiology of stent thrombosis. Summary Intravascular imaging has been shown to provide valuable information regarding the etiology of ST and helps in guiding intervention for these lesions.
