Impact of Severe Acute Respiratory Syndrome Coronavirus 2 Variants on Short- and Mid-term Cardiac Outcomes in Multisystem Inflammatory Syndrome in Children.

Cardiac outcomes of 131 children with multisystem inflammatory syndrome (MIS-C) were examined. The majority of the cohort was male (66.4%) and half were Black (49.6%). Cardiac involvement was evident in 25% of the cohort at diagnosis. Favorable short- and mid-term outcomes were documented on follow-up, irrespective of the severe acute respiratory syndrome coronavirus 2 variants causing the infection.
