Zusammenfassung
Conventional coronary angiography allows a two-dimensional representation of the three main supply vessels of the heart by application of a contrast agent. Beginning stenoses, as well as restrictions by deposits in the vascular system, are illustrated by different gray gradations. Accurate differentiation between thrombus, calcification or vascular spasm can be verified by optical coherence tomography (OCT) or FFR analysis. By the fractional-flow reserve (FFR) method significant changes of the vessel, by the administration of the stress hormone (adenosine) are visualized. In the case of a stenosis, the relations…
