Abstract
Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome which may be related to lethal condition. Although several modalities including medical therapy have been suggested, agreement on optimal treatment has not yet been determined. We describe a case of SCAD which was presented as ST-segment elevation myocardial infarction, and treated successfully with medical treatment. Coronary angiography, intravascular ultrasound and multi-detector computed tomography showed the serial changes of this disease entity.
