Cardiomyopathy presenting prenatally with functional tricuspid and pulmonary atresia.

Cardiomyopathy is a rare diagnosis in the fetus that usually presents as a dilated, poorly functioning ventricle. We present the case of a fetus that developed functional tricuspid and pulmonary atresia due to progressive right ventricular cardiomyopathy. The baby was supported with prostaglandin and inotropic infusions after delivery, eventually weaning off without need for surgical intervention. This case illustrates the prenatal findings that evolved and the successful postnatal management.
