Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial ischemia, especially in the young, because of intramural hematoma (IMH) or intimal dissection. It is not associated with atherosclerosis or trauma. Since its first description by Pretty in 1931, an increasing number of cases has been described in the past decade due to registries as well as the use of coronary angiograms and intracoronary imaging. There are no randomized, prospective trials to guide management and much of the available data are based on observational and retrospective analyses.
