Stenting of bilateral arterial ducts in complex congenital heart disease.
Bilateral arterial ducts serving nonconfluent pulmonary arteries is a very rare pattern of pulmonary blood flow in congenital heart disease with pulmonary atresia. In this setting, neonatal ductal closure might result in abrupt pulmonary hypoperfusion and life-threatening systemic hypoxia, thereby indicating emergent surgical palliation or repair. However, percutaneous arterial duct stenting might be an alternative to surgery, especially in high-risk patients. This article reports on two critical neonates with complex heart disease and discontinuous pulmonary arteries dependent on bilateral arterial ducts who successfully underwent transcatheter ductal stenting as first-step palliation toward lower-risk corrective surgery.
