[Chest pain at 32 weeks' gestation: pregnancy-related spontaneous coronary artery dissection]. / Thorakale Schmerzen in der 32. Schwangerschaftswoche : Spontane Dissektion eines Koronargefäßes in der Schwangerschaft.

A 32-year-old woman at 32 weeks gestation presented with cardiac arrest due to ventricular tachycardia following acute chest pain at home. After immediate defibrillation with return of spontaneous circulation (ROSC), an ST segment elevation myocardial infarction due to coronary artery dissection was confirmed. Two drug-eluting stents were implanted and she was placed on dual antiplatelet therapy (DAPT). The echocardiogram showed akinesis of the apex and anterior wall. The patients risk for stent thrombosis was considered high and therefore DAPT was continued until cesarean section at 35 weeks gestation. Intraoperatively she received two units of packed red blood cells, one platelet concentrate, 4 g fibrinogen and 2 g tranexamic acid. Left ventricular ejection fraction deteriorated 8 days after delivery and the patient developed congestive heart failure.
