Fig. 31.1 Concepts for non-invasive assessment of myocardial ischemia 31.2 Perfusion CT The strength of perfusion imaging is visualizing the myocardial blood flow on which myocardial metabolism depends. Perfusion MR…
Fig. 20.1 Functional anatomy of coronary arterial system. The coronary artery system has three components with different functions: conductive epicardial coronary arteries, arterioles, and capillaries although the borders of each…
Histopathologic findings Image features OCT IVUS Calcification Heterogeneous Very high reflectivity Sharply well-delineated Shadowing Low reflectivity Low attenuation Fibrous plaque Homogeneous Homogeneous High reflectivity High reflectivity Low attenuation Lipid pool…
Blush 0 No appearance of blush or opacification of the myocardium Blush 1 Presence of blush but no clearance of contrast (stain is present on the next injection) Blush 2…
Fig. 15.1 Representative images of pre-procedural OCT images with poor preparation. Visualization of the distal portion of the MLA was not achieved because contrast agent could not pass the MLA…
Fig. 18.1 Representative optical coherence tomography (OCT) image of metal stent. OCT has a limitation to be unable to show the vessel behind the metal stent which is powerful light…
Fig. 19.1 (a) Coronary angiography of a patient presenting with unstable angina shows a significant left main ostial stenosis (arrow) with concomitant ambiguous angiographic lesion in proximal left anterior descending…
Fig. 27.1 The receiver-operator characteristic curve analysis to assess the diagnostic accuracy of angiographic/IVUS parameters for the prediction of functional significance in both MV and SB ostial lesions. In MV…
Normal intima Single-layer appearance or three-layer appearance with intimal thickness < 0.3 mm Minimal atherosclerotic burden ≤20% of VA occupied by plaque Moderate atherosclerotic burden >20%, ≤40% of VA occupied by…
Fig. 25.1 Observed cardiac death rates over the follow-up period in patients undergoing revascularization vs. medical therapy as a function of the amount of inducible ischemia. Increase in cardiac death…
