Abstract
Coronary artery dilatation has been observed with coronavirus disease 2019 (COVID-19)-associated multisystem inflammatory syndrome in children (MIS-C), which is more common in those with Kawasaki-like disease. MIS-C is a clinical syndrome in children and adolescents; its signs and symptoms, as well as cardiac manifestations, are similar to Kawasaki diseases, such as coronary artery dilation, coronary aneurysms, and ventricular dysfunction. The occurrence of coronary artery dilatation in asymptomatic pediatric patients following COVID-19 infection has not been well documented in the literature. Thus, in this article, we present four cases of coronary artery dilation in children with a past history of COVID-19 infection who had very few or no symptoms and were referred to us for vague chest pain and palpitation. As a result, a high index of suspicion is required, and any patient complaining of chest pain and palpitation with a history of COVID-19 exposure should not be ignored and be given proper coronary artery evaluation. This article also raises the question of whether every child infected with COVID-19 should have an echocardiogram.
