Pregnancy-associated spontaneous coronary artery dissection.

Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction that occurs particularly in women during the pregnancy and in the postpartum period. We describe a dramatic case of pregnancy-related spontaneous left main coronary artery dissection that resulted in acute myocardial infarction with severe left ventricular dysfunction and was complicated by acute heart failure and cardiogenic shock. Urgent revascularization and restoration of myocardial perfusion that were performed in this case resulted in marked left ventricular function recovery and clinical improvement.
