Asymptomatic at birth because of adequate systemic perfusion through a PDA and initially high pulmonary vascular resistance
As the PDA begins to close and pulmonary vascular resistance decreases, may develop:
Hypotension
Acidosis
Respiratory distress
Symptoms can rapidly progress from cyanosis, increased respiratory distress, and poor feeding to<unk>  failure and cardiogenic shock
Hypotension
Acidosis
Respiratory distress
Hypoplastic left heart syndrome
Cyanotic
Total anomalous pulmonary venous return
Tetralogy of fallot
Transposition of the great arteries
Tricuspid atresia
Branchial cleft anomaly
Atrio-esophageal fistula
