BACKGROUND: Studies about the incidence and severity of coronavirus disease 2019 (COVID-19) in children are still significantly lower than those in adults. Moreover, data on the effect of COVID-19 in children with congenital heart disease (CHD) are limited. To the best of our knowledge, this study first reported mortality in a child with CHD who acquired COVID-19. CASE SUMMARY: A 16-month-old boy presented to the emergency department due to shortness of breath, fever, cough, and poor oral intake. He tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). He required mechanical ventilation for rapidly progressing respiratory failure. The patient had a large mid-muscular ventricular septal defect (VSD) that was closed percutaneously at the age of 13 months. Moreover, we followed his hospital sequelae from admission to death. DISCUSSION: This child had multiple risk factors, including malnutrition and persistent pulmonary hypertension (PH) after late closure of the VSD. The pre-existing PH could have been aggravated by the lung condition associated with COVID-19 and the respiratory failure triggered by SARS-CoV-2 infection. The patient presented with ventricular systolic dysfunction, elevated troponin serum levels and newly developed trifascicular block, which were indicative of myocardial injury. The elevated inflammatory markers and multi-organ dysfunction seem to corroborate multisystem inflammatory syndrome in children, which was described recently among paediatric patients with COVID-19.
