Peak left atrial longitudinal strain: A potential diagnostic entity in children with multi-inflammatory syndrome in children.

ABSTRACT

The multi-inflammatory syndrome in children is a poorly understood febrile illness potentially linked to an immune response to COVID-19 infection. The disease is characterized by fever and elevated acute-phase reactants. A number of children with clinical and laboratory evidence of cardiovascular involvement have normal echocardiograms by conventional assessment. The peak left atrial longitudinal strain obtained by atrial deformation analysis could potentially be diagnostic of this condition in children who do not have abnormalities identified on conventional assessment.
