A Case of Neonatal Transient Tricuspid Regurgitation with Cardiomegaly in Fetal Period

ABSTRACT

Tricuspid regurgitation(TR) with normal heart structure during fetal life is a frequent functional phenomenon with a prevalence of six to seven percent. Isolated severe congenital TR, however, is an uncommon cause of neonatal congestive heart failure, cyanosis and massive cardiomegaly. We experienced a case of severe transient neonatal TR presented as massive cardiomegaly during fetal life which was normalized in the postnatal period.
