Abstract

Our study describes perivascular epicardial fat stranding, which has the potential to improve the detection of higher-risk patients with coronary atherosclerosis or can act as a marker of a non-atherosclerotic cause of stenosis (ie, spontaneous coronary artery dissection [SCAD]). Perivascular fat stranding was seen in 5% of low-to-intermediate pretest risk patients found to have moderate or higher degrees of stenosis (Coronary Artery Disease Reporting and Data System [CAD-RADS] 3–5) and was seen less commonly along with the classic high-risk plaque features (vulnerable plaque, CAD-RADS modifier V). Recognition of perivascular fat stranding may be helpful in identifying culprit lesion, SCAD, and patients at elevated risk for acute coronary syndrome.
