A 40-year-old woman, pregnant 2, para 1, with a personal history of right thyroid lobectomy and gestational diabetes. Routine ultrasound screening on week 20 of pregnancy revealed mild right ventricle hypoplasia associated with mild pulmonary artery hypoplasia. The tricuspid valve showed a slight limitation in the opening, was hypoplastic and present mild regurgitation. Right outflow tract presented antegrade flow without aliasing and a functioning pulmonary valve. Amniocentesis was normal 46 XX and 22q11 deletion syndrome was ruled out and the patient continued the gestation. In the follow up, tricuspid valve inflow presented biphasic pattern, but the appearance of the valve with the opening was not the usual, we thought that there was a dysplastic valve, but this feature was due to the prolapse of the membrane through the tricuspid valve during diastole. It was objective in pulse wave Doppler of tricuspid valve inflow as an extra wave. The pregnancy ended with uncomplicated breech vaginal delivery, with newborn of 2420 grams, 9/9, pH 7.11. The baby was asymptomatic without cyanosis and it was confirmed the diagnosis of mild right ventricle hypoplasia associated with a membrane floating in right atrium. The presence of a membrane in the right atrium that causes an obstruction in the ventricular filling leads us to the diagnosis of cor triatriatum dexter (CTD). CTD is a rare cardiac abnormality in which the right atrium is divided into 2 compartments by a membrane. The clinical manifestations are directly related to the degree of septation of the right atrium, the degree of obstruction, and the associated congenital abnormalities. Right ventricle hypoplasia is the most frequent of these. The prenatal counseling for this pathology can be complicated due to the difficult diagnosis and the uncertainty about neonatal circulation, whether it be univentricular or biventricular.
