STEMI associated with SARS-CoV-2 infection and the use of ECMO as a potential therapeutic approach in addition to the PCI

A 55-year-old male presented to the emergency department with the complaints of chest pain that started 4 h before presentation. Pain was located over the anterior chest, 5 out of 10 intensity, with radiation to the left arm. Chest x-ray on admission showed severe diffuse bilateral pulmonary infiltrates concerning for COVID-19 pneumonia. Electrocardiogram showed inferior and lateral ST-segment elevation compatible with acute inferolateral myocardial infarction. Successful percutaneous coronary intervention (PCI) of the proximal and mid-right coronary artery using the balloon angioplasty and drug-eluting stent was performed. Post-PCI stenosis was 0% with a thrombolysis in myocardial infarction (TIMI) flow of 3. Five-day course of azithromycin and hydroxychloroquine was completed with no improvement overall. Patient received two doses of 400 mg of tocilizumab intravenously on hospital days 5 (HD#5) and #6. The patient was proned, on FiO₂ 100%, PEEP 15 cm H₂O, on epoprostenol sodium and paralytics and eventually received venovenous ECMO, which improved outcome.
