Background:
When medical treatment of a symptomatic arterial duct in a preterm infant fails, management is surgical.
Patients And Methods:
10 preterm neonates referred to a tertiary cardiac centre for treatment of a symptomatic patent arterial duct who underwent cardiac catheterisation with the intention of device closure.
Results:
Successful catheter device closure of the arterial duct in nine preterm infants is described.
Conclusion:
In selected cases, catheter device closure may offer an alternative to thoracotomy and surgical ligation.
