ABSTRACT
Myocardial infarction complicates approximately 1 in 10,000 pregnancies [1]. Coronary artery dissection is the leading cause of pregnancy-related myocardial infarction during the postpartum period. Proposed etiologies include altered endocrine status, hemodynamic stress, eosinophilic inflammatory infiltrate, and disruption of vasa vasorum. Definitive diagnosis is made by coronary angiography. Treatment has not been well defined. Strategies include medical management, stenting, and coronary artery bypass grafting. Here, we report the postpartal dissection of all 3 coronary arteries and of the left main coronary in an in vitro-fertilized, 40-year-old woman who, after giving birth to a newborn by cesarean section, presented with myocardial infarction and required urgent coronary artery bypass surgery. Spontaneous coronary dissection that predominantly affects young women is rare and is often dramatic. One-third of the cases occur during pregnancy or in the postpartum period. Our case report is unique; postpartum coronary artery dissection in a patient of any age that was fertilized in vitro is very rare.
