Abstract

Spontaneous coronary artery dissection (SCAD) is an uncommon but important cause of myocardial ischemia associated with a high mortality rate. Its aetiology, incidence and pathogenesis are still unknown. It is characterized by the presence of a hematoma and/or the separation of the different layers in the arterial wall, causing vessel lumen stenosis. The clinical manifestation depends on the extent and limitation of the blood flow caused by the dissection, and it varies from an asymptomatic presentation to acute myocardial infarction (50-75%), sudden cardiac death (0.5%) or heart failure.
