Coronary angiography, Multidetector computed tomography, Coronary artery disease, Coronary atherosclerosisAbstract
The evolution of CCTA has been remarkable in the last 20 years, becoming now the first-line test in numerous clinical scenarios in patients with coronary artery disease (CAD). New AHA/ACC, UK and European guidelines strongly advocate CCTA in patients with stable or chronic CAD. The addition of functional testing (FFR-CT/PCT) further expands the utility of CCTA by allowing simultaneous assessment of cardiac anatomy and function. The possibility of displaying non-obstructive coronary atherosclerosis in a noninvasive manner allows CCTA to diagnose CAD earlier, facilitating the
implementation of timely preventive treatments with better performance in this field than functional stress tests, which usually require severe stenosis to detect the disease. The validation of CCTA following large-scale clinical trials, such as PROMISE and SCOT-HEART, continue to reinforce the
clinical utility of this test. Technological advances in image quality, study acquisition, post-processing, and radiation dose reduction allow for wider and safer use of this diagnostic modality today, as recommended by current guidelines and as we see in our experience in this field.
