Spontaneous coronary artery dissection during pregnancy and post partum.

This report describes a 35-year-old 40 week pregnant woman who was hospitalized with a diagnosis of acute anteroseptal myocardial infarction. She sustained another, infero-posterior, infarction 4 days later. Coronary arteriography performed after successful Cesearean section displayed primary dissections of the right as well as both left coronary arteries. Her subsequent clinical course was uneventful with medical therapy. This patient is the first non-surgically treated survivor of peripartal spontaneous coronary artery dissection with a myocardial infarction prior to delivery.
