It was found that 81% of patients lost some contractile function in the left ventricle during the acute phase of illness, yet, by months three and four, contraction function had returned to normal. Moreover, MIS-C did not cause lasting coronary artery abnormalities.

“Recovery among these children was excellent. These results have important implications for our health care teams managing care for children with MIS-C. Our findings may also provide guidance for a gradual return to playing sports after cardiac clearance three to four months later. Tests needed for clearance include an electrocardiogram and echocardiogram. We also recommend cardiac MRI for children who have highly abnormal baseline cardiac MRI during the acute stage or show evidence of continued severe left ventricle dysfunction,” says the study’s senior author Anirban Banerjee, M.D., a professor of clinical pediatrics at the University of Pennsylvania Perelman School of Medicine and an attending cardiologist with the Cardiac Center at the Children’s Hospital of Philadelphia, both in Philadelphia.
