Increased duration and similar outcomes of V-V ECLS in patients with COVID-19 ARDS compared to non-COVID ARDS: Single center experience.

Background: Veno-venous extracorporeal life support (V-V ECLS or V-V ECMO) has been adopted as a rescue support in severe cases of COVID-19 ARDS. Initial reports on the use of V-V ECLS in COVID-19 patients reported very high mortality rates (57%-94%), but subsequent studies showed much lower rates (30%-40%). The aim of this study is to analyze demographic features, clinical course and outcomes of COVID-19 treated with V-V ECLS during the Italian 'third wave', in which the alpha variant was prevalent in the country.

Multisystem Inflammatory Syndrome Following SARS-CoV-2 Infection in Children: One Year after the Onset of the Pandemic in a High-Incidence Area.

SARS-CoV-2 infection in children can trigger cardiovascular manifestations potentially requiring an intensive treatment and defining a new entity named Multisystem Inflammatory Syndrome in Children (MIS-C), whose features partially overlap with Kawasaki Disease (KD). A cross-sectional study including all diagnoses of MIS-C and KD from April 2020 to May 2021 in our metropolitan area was conducted evaluating clinical, laboratory (including immunological response, cytokines, and markers of myocardial damage), and cardiac (coronary and non-coronary) features at onset of the diseases. Evolution of ventricular dysfunction, valve regurgitations, and coronary lesions was documented.

Myocarditis and coronary aneurysms in a child with acute respiratory syndrome coronavirus 2.

A 6-year-old African boy with multi-viral infection including parvovirus B19 and severe acute respiratory syndrome coronavirus 2 was admitted for persistent fever associated with respiratory distress and myocarditis complicated by cardiogenic shock needing ventilatory and inotropic support. Coronary aneurysms were also documented in the acute phase. Blood tests were suggestive of macrophage activation syndrome.
