Postpartum coronary artery dissection.

A 27-year-old woman experienced anterior myocardial infarction three weeks after the delivery of her second child. Coronary arteriography subsequently showed primary dissection of the left coronary artery. This patient is believed to be the second reported survivor of angiographically proven peripartal left coronary artery dissection and the only such patient to achieve and maintain asymptomatic status for a prolonged period without operative intervention.
