Intravenous Immunoglobulin Nonresponsive Symptomatic Myocarditis during the Acute Stage of Incomplete Kawasaki Disease

ABSTRACT

We report the case of a 7-year-old boy who showed treatment-nonresponsive hypotension (59/29 mmHg) and decreased left ventricular systolic function (fractional shortening 22%) in the acute stage of Kawasaki disease (KD). The present case serves to highlight that methylprednisolone pulse therapy should be considered in patients with intravenous immunoglobulin nonresponsive symptomatic myocarditis during the acute stage of KD.
