CORONARY COMPUTED TOMOGRAPHY ANGIOGRAPHY IN PATIENTS WITH ISCHEMIC HEART DISEASE
Aim. To present an overview of the current state of coronary computed tomography angiography (CCTA). To compare coronary computed tomography angiography (CCTA) and coronary angiography in diagnostics of atherosclerosis and congenital coronary arteries anomalies in patients with ischemic heart disease (IHD). Material and methods. Scientiﬁc medical literature searched for articles with clinical relevance on CCTA in diagnostics of coronary artery disease and retrospective study 162 patients with chronic IHD was performed. Results and discussion. CCTA allows to visualize heart vascular network structure, coronary arteries distribution pattern, deﬁne congenital heart diseases, and atherosclerotic coronary walls impairment. CCTA is used for visualization of coronary arteries stenosis, restenosis after previous coronary interventions, shunts patency, and coronary wall calcium accumulation. In 93% of cases CCTA ﬁndings were as follows: absence of stenosis in 16% of cases, hemodynamically insigniﬁcant stenosis in 24%, and hemodynamically signiﬁcant stenosis in 60% of cases. Conclusion. CCTA is useful not only planning patients for coronary angiography (CAG), but also in an exclusion from CAG.
