Correlations Between the Contrast Density Gradient along the Coronary Stents and Functional Significance of In-stent Restenosis

Abstract

Introduction: Coronary artery disease (CAD) is the leading cause of death worldwide and is associated with a significant socio-economic impact. In many cases, patients are treated with implanted coronary stents that carry a significant risk for reobstruction. The aim of our study was to evaluate the importance of coronary computed tomography angiography (CCTA) in evaluating the significance of in-stent restenosis lesions and for establishing the indication for reintervention in these cases.
