Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial infarction in young women. An association of fibromuscular dysplasia (FMD) with SCAD has been well established; a significant proportion of SCAD patients may have typical FMD findings in other noncoronary arteries. The current consensus recommends arterial imaging screening from head to pelvis using computed tomography angiography (CTA) or magnetic resonance angiography (MRA) in SCAD. Genetic testing for FMD should be considered in high-risk cases. We present two cases of SCAD associated with FMD and discuss the significance of genetic screening in such patients.
