Physical examination
- A systolic murmur is often heard in the neonate.
- A small percentage of patients have Noonan's syndrome
- Small stature, retarded, triangle-faced shape, webbed neck, ptosis, hypertelorism, low set ears, and pectus.
- Noonan syndrome is familial.
- If the lesion is severe (>75 mm Hg) then there is a giant a wave secondary to the reduced compliance of the RV.
- There is a loud systolic ejection murmur loudest in the second left intercostal space and peaking in late systole.
- In severe forms, the pulmonic component of the second heart sound may be missing.
