Extra
- Persistently ↑ pulmonary vascular resistance → continued R-to-L shunting across PDA (i.e., persistent fetal circulation)
Risk factors:
- Compare with coarctation of the aorta, which will present with diminished pulses
Risk factors:
- Lung hypoplasia (e.g., congenital diaphragmatic hernia, Potter sequence)
- Infection (e.g., pneumonia)
- Meconium aspiration
- However, some patients have no identifiable cause and simply have a slower decline in PVR
- Compare with coarctation of the aorta, which will present with diminished pulses
| Diagnosis | Transient tachypnea of the newborn (TTN) | Respiratory distress syndrome | Persistent pulmonary hypertension |
|---|---|---|---|
| Pathophysiology | Alveolar fluid not cleared properly at birth | Alveolar collapse and atelectasis due to lack of surfactant | Right to left shunting due to high pulmonary vascular resistance resulting in hypoxia |
| Clinical features | Tachypnea resolves by day 2 | Respiratory distress (preterm birth) | Tachypnea and cyanosis |
| Chest x-ray | Perihilar linear streaking bilaterally | Ground glass (reticulogranular), air bronchograms, decreased lung volumes | Clear lung fields, decreased pulmonary vascularity |
