| Summary: | Introduction. Critical congenital heart diseases (CHD) are mostly
duct-dependent and require stable systemic-pulmonary communication. In order
to maintain patency of the ductus arteriosus (DA), the first line treatment
is Prostaglandin E1 and the second step is the surgical creation of
aortic-pulmonary shunt. To reduce surgical risk in neonates with the critical
CHD, transcatheter stenting of DA can be performed in selected cases. Case
Outline. A four-month old infant was diagnosed with the pulmonary artery
atresia with ventricular septal defect (PAA/VSD). The left pulmonary artery
was perfused from DA, and the right lung through three major aortopulmonary
collaterals (MAPCAs). A coronary stent was placed in the long and critically
stenotic DA, with final arterial duct diameter of 3.5 mm, and significantly
increased blood supply to the left lung. After the procedure, the infant’s
status was improved with regard to arterial oxygen saturation, feeding and
weight gain. During the follow-up, one year later, aortography revealed
in-stent stenosis. The left pulmonary artery, as well as the branches, was
well-developed and the decision was made to proceed with further surgical
correction. Conclusion. Stenting of DA can be an effective alternative to
primary surgical correction in selected patients with duct-dependent CHD.
