[Spontaneous dissection of the left main coronary artery: a case report and review of the literature].

: Primary spontaneous coronary artery dissection occurs rarely. Compared to usual acute coronary syndromes, it occurs in relatively young people, particularly in women in the peripartum or early post-partum period. The etiology of spontaneous coronary artery dissection remains unclear; there have been less than 150 cases reported in the literature, and only 28 cases documented in the left main coronary artery. This article reports the clinical course of a patient with primary spontaneous left main coronary artery dissection who was treated with coronary artery bypass grafting after clinical steadiness.
