Prognostic utility of echocardiographically derived left ventricular strain in assessing neonatal enteroviral myocarditis outcome.

Background: Neonatal enteroviral myocarditis is a rare but potentially fatal illness. We sought to identify echocardiographic markers at diagnosis that could help risk-stratify infants for poor outcome and to characterise late sequelae.

Methods: We reviewed data for infants <30 days of age diagnosed with enteroviral myocarditis between 1999 and 2019 at Children's Wisconsin.
