Idiopathic spontaneous coronary artery dissection presenting as acute myocardial infarction in a young boy.

Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction. It is more commonly seen in the younger age group particularly in women. We report a case of 14-year-old boy that presented with acute myocardial infarction (MI), with left ventricular (LV) dysfunction and was detected to have left main coronary artery dissection on coronary angiography. Myocardial perfusion imaging did not show any evidence of reversible ischemia. Patient was managed conservatively and was marginally improved. This case highlights one of the rare causes of myocardial infarction and the use of myocardial perfusion imaging in selecting treatment options for management of this rare entity.
