Spontaneous coronary artery dissection: report of two cases and a 50-year review of the literature.

Spontaneous coronary artery dissection (SCAD) is a rare condition that can cause acute myocardial infarction and sudden death. This entity occurs predominantly in women. Although several mechanisms have been postulated, no single etiology completely explains the pathogenesis of SCAD. Patients who survive SCAD have been treated with various modalities. Prompt diagnosis and early institution of appropriate treatment are usually associated with successful outcome. We report two cases of SCAD successfully identified and treated with coronary stenting as well as a comprehensive review of cases of SCAD published since 1952.
