RESUMO
Although atherosclerotic obstruction is the main cause of left main coronary artery (LMCA) disease, it can also be associated with vasospasm. We report a case of a 61-year-old male who presented with ostial stenosis of the LMCA, detected by 64-slice multi-detector computed tomographic coronary angiography (MDCT-CA). Careful review of MDCT and intravascular ultrasound findings showed suspicion of an isolated spasm of the LMCA without a significant atherosclerotic lesion. The patient was successfully treated with nitrates and a calcium channel blocker.

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.
