RESUMEN
INTRODUCTION: The accurate incidence of different cardiovascular consequences of COVID-19 in the pediatric population has been inadequately defined due to ongoing genotype changes in the virus. Although COVID-19 is known to increase inflammatory markers associated with atrial arrhythmias, the contemporary literature has poorly described new onset arrhythmias as a complication in previously healthy neonates with COVID-19. CASE PRESENTATION: A twenty-day-old female term neonate, born by caesarean section with immediate cry, developed labored breathing, cyanosis, and tachycardia after having close contact with a confirmed case of COVID-19. The neonate developed atrial flutter, which was refractory to cardioversion and drugs, namely Amiodarone, Flecainide, and Propranolol. The authors treated the neonate with IVIG. This is the first reported case of atrial flutter in the neonatal period secondary to COVID-19. CONCLUSION: Since the start of the SARS-CoV-2 pandemic, all attention and concerns have been mainly on respiratory manifestations and complications. The cardiovascular complications and treatment have been neglected. This case reports tachyarrhythmia (Atrial Flutter) as an unusual presentation of acute COVID-19 in the neonatal population and shows the role of IVIG in the treatment of refractory arrhythmias.
