Severe COVID-19 post pregnancy complicated by acute thromboemboli resulting in ST-elevation myocardial infarction – A case report.

Publication date: Jan 17, 2024

Introduction: It has been shown that pregnancy can cause alterations in the severity of COVID-19 infection. We demonstrate an immediate post-partum patient diagnosed with severe COVID-19 and subsequently developed acute thrombosis of coronary artery. Case Summary: 35-year-old female unvaccinated for COVID-19 presented in labor and delivered on the same day. Several hours later, she was found to be in respiratory distress and tested positive for COVID-19. On day 7, computerized tomography (CT) of chest revealed bilateral pneumonia and pneumomediastinum. On day 8, she developed chest pain with electrocardiogram (EKG) showing inferior STelevations with troponin I of 0. 6 ng/mL. She was intubated for airway protection and emergent diagnostic angiogram revealed thrombus occlusion of the third right posterolateral segment that resulted in thrombolysis in myocardial infarction (TIMI) 0 flow without evidence of underlying atherosclerotic disease in the remaining vessels. Intracoronary IIb/IIIa inhibitor was administered. Arterial blood gas in the lab revealed profound hypoxia despite being on 100% inspired oxygen. Multidisciplinary decision was made to cannulate patient for venovenous extracorporeal membrane oxygenation (ECMO) to treat severe COVID-19 pneumonia. She was finally decannulated from ECMO on day 65. After prolonged hospital stay, she eventually recovered and was discharged to rehabilitation. Conclusions: The center for disease control (CDC) surveillance has reported that pregnant patients with COVID-19 are more likely to require invasive ventilation and ECMO, and die given the immunological changes during pregnancy. Hypercoagulable state caused by combination of pregnancy and COVID-19 resulting in coronary thrombosis is rarely described in literature, our case demonstrated the paucity of this phenomenon.
