Acute anterior myocardial infarction in the 36th week of pregnancy: A successful stepwise treatment approach

Abstract

Acute myocardial infarction (AMI) is associated with a high incidence of maternal and fetal complications when it develops during pregnancy or the early postpartum period. The pathophysiology involves various factors, including alterations in the vascular wall and hypercoagulability as a result of the hormonal and hemodynamic effects of pregnancy. It frequently occurs due to the development of a thrombus following a ruptured plaque. In addition, coronary artery dissection constitutes a significant cause of AMI in pregnancy. In the literature, the therapeutic approach covers a wide spectrum, ranging from conservative follow-up to percutaneous coronary intervention, urgent bypass surgery, and occasionally, thrombolytic therapy. The success rate is often low; however, maternal and fetal complications are seen more frequently during invasive interventions and bypass surgeries because of the structural changes in the coronary intima and media wall. Presently described is the case of a woman in the 36th week of pregnancy who presented with AMI. The occlusion could not be detected during the primary percutaneous intervention, and thrombolytic treatment and a stepwise percutaneous intervention were performed with a successful result.
