[ANMCO/GISE/SICOA Consensus document: Role of coronary computed tomography angiography in chronic coronary syndromes]

Abstract

Chronic coronary syndromes (CCS) are the most common clinical manifestation of coronary atherosclerosis. Coronary computed tomography angiography (CCTA) is a recent innovation in non-invasive cardiac imaging. It is the only anatomical imaging method that allows direct visualization of the coronary lumen, vessel walls, and atherosclerotic plaques, offering high sensitivity and a strong negative predictive value. CCTA is particularly useful in identifying or ruling out coronary atherosclerosis in the context of CCS and serves as an excellent filter for invasive coronary angiography. Compared to other non-invasive functional imaging tests (stress echocardiography, single photon emission computed tomography, magnetic resonance imaging, positron emission tomography), CCTA provides detailed characterization of both obstructive and non-obstructive plaques, enabling accurate risk stratification and guiding therapy. Recent advances in computed tomography technology and imaging techniques further extend the use of CCTA beyond plaque and stenosis evaluation, offering also functional lesion information. This consensus document aims to detail the technical aspects of CCTA and illustrate its role in optimizing CCS diagnostic and therapeutic management, enhancing precision medicine and personalized patient care.
