Cardiac involvement in a child post COVID-19: a case from Lebanon

Abstract

We report on an 8-year-old boy, who presented to the emergency department at our institution with fever, generalised oedema and hypotension. Investigations revealed anaemia, thrombocytopenia in addition to elevated serum inflammatory markers, a negative COVID-19 PCR test and a positive COVID-19 IgG. His echocardiography was consistent with carditis in otherwise morphologically normal heart with depressed cardiac function, moderate-to-severe mitral valve regurgitation, moderate tricuspid regurgitation with an estimated right ventricular systolic pressure half systemic, trace aortic regurgitation, bilateral small pleural effusions, distended inferior vena cava and normal coronaries. He was started on inotropic support, intravenous immunoglobulin and methylprednisolone, and was transferred to the paediatric intensive care unit. To the best of our knowledge, this was the first case of multisystem inflammatory syndrome in children encountered in Lebanon. The presentation and management were thoroughly described in this article aiming to share our experience and to contribute to the rapidly emerging literature on this syndrome. © BMJ Publishing Group Limited 2021.
