Abstract

We report a neonate with dilated cardiomyopathy and have echocardiographic findings consistent with “functional” tricuspid atresia. There was an echo-bright, plate-like tissue at the tricuspid valve position with no forward flow across it. This report underscores the role of right ventricle intracavitary haemodynamic influence on the tricuspid valve leaflet excursion and demonstrates a phenomenon of “pseudo or functional tricuspid atresia” mimicking tricuspid atresia in a patient with acute presentation of cardiomyopathy.
