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. 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…
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…
Fig. 2.1 Post-acoustic shadows due to severe calcified lesions, metal stent struts, and guidewires. (a) Heavy calcified lesions mask the plaque underneath between the 9 and 3 o’clock positions (arrowheads)….
Fig. 26.1 The relation of percent diameter stenosis of the left circumflex artery to resting mean flow (dashed line) and hyperemic response (solid line) after intracoronary injection of Hypaque in…
Fig. 23.1 Correction of transducer height . If the transducer is higher than aorta height level, the measured pressure can be lower than the real pressure (a) and vice versa…
Fig. 21.1 Four basic requirements for FFR measurement. (1) Aortic pressure (Pa) measured by the conventional catheter-based blood pressure system. (2) Distal coronary pressure (Pd) measured by the pressure sensor….
Fig. 7.1 A representative images showing stent symmetry and eccentricity . Minimum and maximum stent diameters with 1 mm interval over the length of the device were shown. Stent (Xience…
Fig. 8.1 Optimal minimal stent area in the sirolimus-eluting stent (a), paclitaxel-eluting stent (b), zotarolimus-eluting stent (c), and everolimus-eluting stent (d) to predict angiographic restenosis (Reproduced from Song et al….
Fig. 29.1 The mechanism of a low FFR after PCI In previous studies included relatively simple lesions with an overall low coronary artery disease burden, post-PCI FFR > 0.90 has been considered…
