[Spontaneous coronary artery dissection and ST-segment elevation myocardial infarction (STEMI)]

Abstract

Spontaneous coronary artery dissection (SCAD) is a poorly understood and under-diagnosed entity of acute coronary syndrome, affecting predominantly young women. On coronary angiography, the diagnosis remains challenging, particularly in case of intramural hematoma without intimal rupture. Intracoronary imaging, especially by optical coherence tomography (OCT), provides an incremental value in terms of diagnosis and management. We report the case of a 49-year-old woman admitted for STEMI caused by an intramural hematoma. In the discussion part, we aim to review the epidemiology, physiopathology, diagnosis, management and long-term prognosis of SCAD.
