Postpartum coronary artery dissection complicated by heparin-induced thrombocytopenia and thrombosis.

ABSTRACT

A 32-year-old woman presented with an acute anterior-lateral myocardial infarction 7 days postpartum. Coronary angiography revealed an occlusive left main coronary artery dissection. After coronary artery bypass surgery the patient's cardiac function improved and stabilized. Thrombocytopenia and a femoral artery thrombosis after 9 days of heparin exposure marked the development of heparin-induced thrombocytopenia and thrombosis that was successfully managed with argatroban, a direct thrombin inhibitor anticoagulant.
