Table 1. Non-invasive atherosclerosis evaluation by CCTA.
CCTA atherosclerosis evaluation | |
---|---|
Qualitative features | Quantitative analysis |
– Positive remodeling – Low-attenuation plaque – Napking ring sign – Spotty calcification | – Low-attenuation plaque volume (mm3) – Non-calcified plaque volume (mm3) – Calcified plaque volume (mm3) |
Clinical insight for the interventionalist | |
– All adverse plaque features could be associated with higher rate of peri-procedural MI – Adverse plaque features could be associated with myocardial ischemia, independently from lumen stenosis degree at invasive angiography – Extensive presence of calcified plaque could be associated with the need of dedicated intra-procedural techniques (i.e., rotablator, intravascular lithotripsy) |
