Physical Examination

Appearance of the patient

• 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.

Neck

• If the lesion is severe (>75 mm Hg pressure gradient) then there is a giant a wave secondary to the reduced compliance of the right ventricule.

Heart

• A systolic murmur is often heard in the neonate.
• There is a loud systolic ejection murmur loudest in the second left intercostal space which peaks in late systole.
• In severe forms, the pulmonic component of the second heart sound may be missing.
