Neonates usually presenting with tachypnea, tachycardia,irritability, and unwillingness to take either breast or bottle feedings during the early weeks of life, all manifestations of heart failure.

Infants who survive for longer periods, recurrent respiratory infections, dyspnea, and failure to thrive are usually present, and cyanosis is more apparent secondary to rising PVR.

Older children may occasionally present with increasing cyanosis (Eisenmenger syndrome).

- Signs of heart failure including gallop rhythm some times.
- A prominent left parasternal systolic murmur
- Aortic early diastolic murmur
- Continuous murmur is noted occasionally
and is most often due to stenosis at the origin of one or
both pulmonary arteries.
