| Abstract: | Cor triatriatum dexter is an uncommon congenital heart defect that may cause cyanosis in infancy and mimic more complicated forms of congenital heart disease. This lesion occurs when the eustachian valve, or right venous valve of the inferior vena cava, is unusually large and causes obstruction to right ventricular filling. The eustachian valve is frequently seen by 2-dimensional (2-D) echocardiography and is a normal finding if the valve is small.1 This report describes the echocardiographic identification of an obstructive eustachian valve causing cyanosis. |
