Given the radiographic findings, an echocardiogram was performed to investigate the etiology of the cardiomegaly and pulmonary vascular congestion.
Conclusions found:
- patent foramen ovale (PFO) present with right to left shunt
- normal cardiac anatomy with systemic right ventricle (RV) pressures
- moderate pulmonary and tricuspid valve insufficiency
- mild mitral regurgitation
- moderately depressed RV function
The diagnosis of persistent pulmonary hypertension of the newborn (PPHN) was confirmed and the baby girl was treated accordingly.
