Neonatal cyanosis: diagnostic and management challenges.

Abstract

Neonatal central cyanosis is always a sign of serious pathological processes and may involve diverse organs and impose a significant diagnostic and therapeutic challenge. Here, we report an unusual presentation of Ebstein's anomaly, a rare congenital heart malformation, as the cause of central cyanosis in a one-week-old full-term infant. Initiation of PEG(1) therapy in neonates with Ebstein's anomaly always needs a very careful consideration because of a high risk for the development of a "circular shunt" leading to severe deterioration of multiple organs perfusion.
