It has been suggested that SCAD could be a reflection of an underlying systemic arterial disorder, namely fibromuscular dysplasia (FMD), a non-inflammatory sys- temic arteriopathy. A 59-year-old woman, former smoker, with hypertension and no other medical background presented with non-ST elevation myocardial infarction. Emergent coronary angiography revealed patent major epicardial vessels with subtle irregularities, and an abrupt calibre diminish- ment (tapering) of a distal marginal branch taking off from the circumflex (Panel A,arrows; see Supplementary online, Video S1). A tentative diagnosis of SCAD was made (angiotype II, intramural haematoma) and a conservative attitude adopted. After an uneventful course, the patient was scheduled for surveillance angiography 6 months later, in which SCAD diagnosis was confirmed by evidencing vessel restoration (Panel B, arrows; see Supplementary online, Video S2). Further investigation of non-coronary arterial beds was performed with magnetic res- onance angiography (MRA) in a two-in-one screening procedure assessing cervical-cephalic and abdominal-iliac arterial systems. Cerebral vessels appeared structurally normal but markedly tortuous (Panel C). No aneurysms were detected. Distal abdominal aorta showed tan- dem focus dilatations in a ‘string-of-beads’ pattern (Panel D, arrowheads), resembling the FMDs recognizable feature. However, renal arteries appeared normal (circles). Moreover, iliofemoral arteries showed marked tortuosity, without signs of fibromuscular dysplasia. Although systemic FMD encountered in SCAD patients most typically involves renal, carotid and femoral arteries, other territories may be separately affected as illustrated in this case, which justify performing an extended screening. Because of its non-invasiveness and absence of radiation, MRA represents an ideal tool for screening systemic arteriopathy in SCAD patients.
