Abstract: A 60-year-old woman was admitted for an acute coronary syndrome. Coronary angiography showed a spontaneous coronary artery dissection (SCAD) in the left anterior descending coronary artery (A). A typical image of fibromuscular dysplasia (FMD) was also observed in the right renal artery (B). Optical coherence tomography (OCT) (C) revealed alternating areas of thickening and thinning of the medial layer, corresponding to the typical image of "string of beads" readily identified in the longitudinal reconstruction of the OCT and also in angiography. A very high prevalence of FMD in non-coronary arteries has been recently reported in patients with DCE. Our findings suggest that OCT may provide unique diagnostic clues in these challenging patients.
