Abstract
-
Isolated right ventricular hypoplasia, unassociated with severe pulmonary or tricuspid valvar malformations, is a rare primary congenital cardiac anomaly in which of the trabecular portion of right ventricle fails to develop. An atrial septal defect or a patent foramen ovale serves as an escape valve. We observed a 2-day-old neonate with this disorder who suffered from cyanosis. The diagnosis was made by Doppler-echocardiography which revealed marked reduction in right ventricular size and right-to-left shunt through the atrial septal defect. There was no other cardiac malformation such as pulmonary atresia or tricuspid atresia.
