Background: While other viral infections occurring in early pregnancy are known to be associated with fetal cardiac malformations, little is known about CMV and its causative role. Only a few case repots have been described reporting a correlation between congenital CMV infection and cardiac defects.Case-report: We report the case of a 7-day-old neonate who was referred to our Pediatric Infectivology Department for maternal cytomegalovirus (CMV) seroconversion during the first trimester of pregnancy and confirmed congenital infection. At first evaluation, the baby presented with a cardiac murmur and signs of acute heart failure, along with jaundice and hypotonia. At cardiac ultrasound, a perimembranous doubly-committed ventricular septal defect and a reduced aortic isthmus diameter were revealed.Conclusion: Despite further large-scale prospective studies are needed to confirm or rule out this association, CMV DNA urine detection might be worth to be considered as part of the diagnostic process in neonates with isolated heart defects.
