CONCOMITANT REPAIR OF AORTOPULMONARY WINDOW AND INTERRUPTED AORTIC-ARCH

Aortopulmonary window with type A interrupted aortic arch was diagnosed in 2 critically ill neonates. Echocardiographic diagnostic methods provided precise anatomic information, which allowed cardiac catheterization to be avoided before operation. Repair was undertaken through a midline sternotomy using hypothermic, low-flow cardiopulmonary bypass with subclavian turndown in one patient and hypothermic circulatory arrest with direct aortoaortic anastomosis in the other. Both methods provided good exposure and allowed favorable anatomic repair.
