Abstract

Since the development of computed tomography (CT) technology over the last decade, coronary CT angiography (CCTA) has become a powerful non-invasive method for evaluating coronary artery disease. Recently, CT has been used to evaluate hemodynamic status beyond anatomy by current trials such as perfusion CT, fractional flow reserve-CT, or transluminal attenuation gradient, which can help determine whether coronary revascularization occurs. Once revascularization is determined, CT can guide whether to use a stent or coronary artery bypass graft (CABG) for the reperfusion method by evaluating the nature of the lesion. In addition, CCTA helps to better define the morphological features of the occluded chronic total occlusion segment such as the occlusion length and presence of calcifications or tortuosity in its course, which are established predictors of success. Finally, CT can assess the patency of a stent or CABG in patients who previously underwent revascularization. Therefore, this review article discusses the various roles of CCTA in coronary revascularization.
