Abstract
PURPOSE OF REVIEW: We provide the readers with a review of cardiac complications in children with multi-system inflammatory syndrome in children (MIS-C) and its short-term outcomes. RECENT FINDINGS: Recent reports described the acute cardiac manifestations of MIS-C in children and provided a glimpse of the short-term outcomes. SUMMARY: Children with MIS-C have been reported to acutely have variable degrees of cardiac findings including abnormal cardiac enzymes, abnormal electrocardiographs, decreased systolic function, coronary artery abnormalities from coronary dilation to giant aneurysms, mitral valve regurgitation, tricuspid valve regurgitation, aortic valve insufficiency, pericardial effusion, diastolic dysfunction, abnormal cardiac strain, and abnormal cardiac MRI. The majority of these abnormalities resolved during short-term follow-up. Further studies are needed to assess if transient or persistent cardiac complications are associated with long-term adverse cardiac events in children with MIS-C.
