- interstitial lung disease
- pulmonary thromboembolic disease
- pulmonary
inflammatory or
capillary disease
- =high pulmonary Pa, mean > 25mmHg
- most kids w/ pul HTN have a large
post-tricuspid shunt w/ high pul blood
flow & low resistance
- e.g. VSD, AVSD, PDA
- Pa falls to normal if
defect surgically
corrected within 6
months old
- if left untreated
- high flow and Pa causes
irreversible damage to
pulmonary vascu bed (pul
vasc disease)
- not correctable
except by
heart/lung
transplant
