Abstract
The clinical course of COVID in the pediatric population is considered to be much milder when compared to adults; however, the occurrence of severe and fatal forms of the disease in children is non-negligible, especially in patients with comorbidities such as prematurity or cardiac disease. We report a case of a newborn with sotalol-controlled fetal ventricular tachycardia, who was postnatally diagnosed with COVID infection. The myocardial injury was sustained on the basis of pericardial effusion, left ventricular dysfunction, rapid progression to coronary artery dilation, and an arrhythmic storm. We believe that, in our case, there is a significant overlap between fetal ventricular tachycardia, associated with impaired left ventricular function, and COVID infection, diagnosed after birth; both factors contribute to the myocardial dysfunction with a fulminant clinical evolution. To our knowledge, this is the first case describing neonatal myocardial dysfunction associated with SARS-CoV infection complicating the clinical course of rare fetal tachyarrhythmia.
