Spontaneous Coronary Artery Dissection: A Review of Pathogenesis, Presentations, Treatment, and Outcomes.

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndromes and sudden cardiac death. The epidemiology, pathogenesis, and optimal approaches to diagnosis and management are poorly understood. Additionally, SCAD as a syndrome is commonly under-recognized and its prognosis is not well studied. Guidelines on management of SCAD have not yet been established. We present three cases of SCAD that varied in their clinical presentation and describe the different management strategies utilized. This is followed by a review of the clinical features, epidemiology, prognosis, and potential treatment strategies for patients presenting with SCAD.
