title: Persistence of bilateral arterial ducts in pulmonary atresia despite confluent branch pulmonary arteries: opportunity for two percutaneous therapeutic alternatives.
abstract: We present a case of a newborn infant with double inlet left ventricle, pulmonary atresia, confluent pulmonary arteries, and bilateral arterial ducts (AD), to discuss the therapeutic alternatives offered by interventional catheterization techniques in this anatomic arrangement. The infant initially underwent stenting of the right AD to stabilize pulmonary blood flow off of prostaglandin infusion. Three weeks later, she developed left pulmonary artery isolation upon closure of the left arterial duct. An additional stent was placed in the pulmonary artery confluence, restoring blood flow to the left lung and significantly improving her oxygen saturations. At 6 months of age she underwent her first surgical procedure, a successful bidirectional cavopulmonary anastomosis with removal of the left pulmonary artery stent and patch enlargement of the pulmonary artery confluence. She continues to do well in clinical follow-up at 16 months of age.
