title: Non-invasive imaging of a coronary bypass stenosis using CT angiography in a patient with negative stress testing.
abstract: In patients with a low or intermediate probability of a coronary artery disease, ultrafast computer tomography (CT) of the coronary arteries and bypass grafts offer a novel approach for the evaluation of the coronary anatomy. The presented case impressively demonstrated the capability of ultrafast CT to show precisely the extent and localisation of a bypass artery stenosis in a patient with mild chest discomfort but negative stress testing. However, widespread screening of coronary artery disease with non-invasive imaging modalities can not be recommended until validated in larger studies that a complete visualization of all coronary arteries and bypass grafts can be achieved.
