Multisystem Inflammatory Syndrome Causing Mixed Cardiogenic Shock in a 34-Year-Old With Influenza A

Multisystem inflammatory syndrome in adults (MIS-A) is a sequela of COVID-19 and can cause mixed cardiogenic and vasodilatory shock. We present the case of a 34-year-old female who presented with mixed cardiogenic and vasodilatory shock and was found to be influenza A positive while also meeting criteria for MIS-A. She responded well to treatment with steroids and intravenous immunoglobulin (IVIG).
