Complete repair of a total defect type aortopulmonary window in an extremely low birth weight neonate

The authors performed a complete repair for a total defect type aortopulmonary window (APW) in an extremely low birth weight neonate weighing 1.1 kg. The APW was repaired using an autologous pericardial patch. A novel cardiopulmonary bypass system with low priming volume allowed a safe surgery for the premature patient.
