Early reports suggested that pediatric COVID-19 cases were less severe in children. Most children requiring intensive care admission in these reports had underlying medical conditions. Shortly after the surge of adult COVID-19 cases in Detroit, Michigan, previously healthy children began to present with shock with multiorgan dysfunction, elevated inflammatory markers, and physical exam findings with features of Kawasaki disease. This disease process was later called multisystem inflammatory syndrome in children (MIS-C.) In this case series, we describe three previously healthy children who presented with severe manifestations of MIS-C, including cardiogenic shock and profound systemic inflammation. These children developed severely depressed myocardial function with end-organ injury and were cannulated to veno-arterial extracorporeal membrane oxygenation (VA-ECMO) due to cardiogenic shock with arrhythmia. All three children improved with VA-ECMO support and anti-inflammatory treatment. All had complete recovery of myocardial function at discharge and 6-month follow-up with no significant morbidity.
