We demonstrate an immediate post-partum patient diagnosed with severe COVID-19 and subsequently developed acute thrombosis of coronary artery.<i>Case Summary:</i> 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.<i>Conclusions:</i> 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.

The hallmark of ARF is a heterogeneous injury, with normal tissue intermingled with a large volume of low compliance and collapsed tissue. Mechanical ventilation is necessary to oxygenate and ventilate patients with ARF, but if set inappropriately, it can cause an unintended ventilator-induced lung injury (VILI). The mechanism of VILI is believed to be overdistension of the remaining normal tissue known as the 'baby' lung, causing volutrauma, repetitive collapse and reopening of lung tissue with each breath, causing atelectrauma, and inflammation secondary to this mechanical damage, causing biotrauma. To avoid VILI, extracorporeal membrane oxygenation (ECMO) can temporally replace the pulmonary function of gas exchange without requiring high tidal volumes (V_T) or airway pressures. In theory, the lower V_T and airway pressure will minimize all three VILI mechanisms, allowing the lung to 'rest' and heal in the collapsed state. The optimal method of mechanical ventilation for the patient on ECMO is unknown. The ARDSNetwork Acute Respiratory Management Approach (ARMA) is a Rest Lung Approach (RLA) that attempts to reduce the excessive stress and strain on the remaining normal lung tissue and buys time for the lung to heal in the collapsed state. Theoretically, excessive tissue stress and strain can also be avoided if the lung is fully open, as long as the alveolar re-collapse is prevented during expiration, an approach known as the Open Lung Approach (OLA). A third lung-protective strategy is the Stabilize Lung Approach (SLA), in which the lung is initially stabilized and gradually reopened over time.
