Hypoplastic right heart syndrome

Case contributed by Dr Mostafa El-Feky


Routine anomaly scan.

Patient Data

Age: 32 weeks gestation
Gender: Male

Diminished volume of the right ventricle with no adequate expansion of its lower segment during systole. Right ventricular size is about half the left one, suggestive of hypoplastic right heart syndrome. No associated tricuspid atresia or regurge. 

The rest of the fetal anatomical survey was unremarkable.

Case Discussion

The decreased size of the right ventricle is suggestive of hypoplastic right heart syndrome. It is a congenital cardiac anomaly characterized by an underdeveloped right side of the heart. Postnatal echocardiography is recommended to confirm findings. No associated incompetent tricuspid valve. 

Care should be taken during ultrasonography to avoid false interpretation of abnormally small cardiac chamber due to inadequate technique as an oblique section through the four-chamber view. Also, the edge-shadowing from the sidewall of the chest that can conceal part of the cardiac chamber.
