Abstract: 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.
