Coronary artery disease (CAD) is characterized by the accumulation of atherosclerotic plaques in the arteries that supply the heart with blood. This disease can be obstructive or non-obstructive, and treatment includes lifestyle changes, medications, and invasive interventions. CAD is a chronic and often progressive disease, with the potential for sudden worsening due to plaque rupture or erosion. Coronary computed tomography angiography (CCTA) has become essential for diagnosing CAD as it provides detailed insights into the condition of the arteries and plaque development. Advances in CCTA technology have enabled reduced radiation exposure and precise characterization of the arteries, which is crucial for medical decision-making. CCTA is used to monitor changes in plaques and to stratify risk in patients. Myocardial revascularization, either through percutaneous coronary intervention or surgically (coronary artery bypass grafting, CABG), plays an important role in the treatment of obstructive CAD. CCTA is also useful for assessing the patency of stents and coronary bypass grafts. CCTA plays an important role in monitoring patients after revascularization, providing information on vessel patency and the status of atherosclerotic plaques. The use of CCTA for revascularization monitoring can significantly contribute to improving treatment outcomes and reducing complications. In this review paper, we describe the role of CCTA in the evaluation of patients after myocardial revascularization.
