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.

Rare but Not Infrequent: Infective Endocarditis Caused by Abiotrophia defectiva.

Endocarditis (IE) is defined by an infection of a native or prosthetic heart valve, the mural endocardium, or an indwelling cardiac device. Although viridan-group streptococci (VGS) and Staphylococci species have collectively been considered as the most common cause of endocarditis, uncommon pathogens may also lead to the disease with significant morbidity and mortality. Abiotrophia defectiva, a nutritionally variant streptococci (NVS), is a virulent bacterium that preferentially affects endovascular structure and is implicated in many culture-negative endocarditis with dreadful complications such as heart failure, septic embolization, and valve destruction. Here, we report a case of a 60-year-old male patient, with a past medical history significant for hypertrophic obstructive cardiomyopathy, who was incidentally found to have mitral valve vegetative mass with an uncommon agent, A. defectiva. The patient was successfully treated with antimicrobial therapy. The objective of this article is to describe the possibility of uncommon cause of common diseases and raises awareness of infective endocarditis caused by A. defectiva among clinicians and microbiologists. Early and proper identification of this pathogen is important to achieve a better outcome.
