Noninvasive Cardiac Imaging in Patients with Known and Suspected Coronary Artery Disease: What is in it for the Interventional Cardiologist?

The long-standing coronary artery disease (CAD) paradigm simplified by the discrimination between patients with or without CAD warrants to be revisited by the insightful information provided by noninvasive cardiac imaging, leading to a comprehensive physiopathological assessment rather than a mainly anatomical approach. This review will address (1) the role of non-invasive cardiac imaging for the appropriate selection of stable patients referred to invasive coronary angiography (ICA), and the evolving concept and prognostic implications of myocardial ischemia; (2) the usefulness of computed tomography coronary angiography for the guidance of percutaneous coronary interventions; and (3) the role and potential clinical impact of novel anatomical and functional non-invasive prognostic markers.
