Multiple recurrences of spontaneous coronary artery dissection in a woman with fibromuscular dysplasia.

A 54-year-old woman with no prior coronary artery disease or cardiac risk factors was diagnosed with spontaneous coronary artery dissection (SCAD) after presenting with an acute coronary syndrome. Over the next 5 years, she experienced four more episodes of SCAD, involving different coronary artery distributions, with evidence of complete angiographic healing following conservative management with antiplatelet therapy and beta-blockade.
