[Why Coronary CTA will affect the diagnosis and management of stable coronary artery disease?].
Until recently, the optimal work-up of patients with stable coronary artery disease (CAD) was based on non-invasive functional tests. Coronary CTA (CCTA) now challenges this standard work-up due to its efficacy to exclude significant coronary artery disease. Current indications for CCTA include symptomatic patients with intermediate pre-test probability of CAD with altered ECG (LBBB, repolarization abnormalities) rendering stress tests useless or patients unable to achieve sustained stress effort, and patients with indeterminate or uninterpretable results on ischemic work-up. A more agressive position is to consider CCTA as the cornerstone of patient management because the limitations and pitfalls of non-invasive techniques open the door to an alternative diagnostic imaging technique, either alone, or in combination with other Imaging techniques after reorganizing the sequence of imaging work-up. Without dismissing the dogma of initial détection of CAD along with prognostic stratification using functional tests, the recent availability of a minimally invasive anatomical test in the management of patients with stress angina, given the known limitations of traditional tests, changes the standard work-up algorithms. This suggests that the diagnostic work-up of patients with CAD is likely to be modified to increase the rôle of CCTA.
