Abstract:
Restrictive atrial communication is rarely reported in tricuspid atresia but when present it can lead to important morbidity. We describe two fetuses with tricuspid atresia with restrictive foramen ovale who were found to have fetal growth failure. Fetal echocardiography detected a restrictive atrial communication by flow acceleration on color Doppler and significant right atrial dilation in one patient; the atrial septum was not well interrogated in the other patient. Restrictive foramen ovale in tricuspid atresia may be associated with fetal growth failure. Color Doppler interrogation of the atrial septum on fetal echocardiogram may help identify this condition prenatally.
