Anomalous origin of left pulmonary artery from aorta with atrial septal defect.

Anomalous origin of left pulmonary artery (ALPA) from aorta with atrial septal defect (ASD) is a rare congenital cardiac malformation. We report a case of ALPA from the aorta with ASD in a 1.8-kg baby. Repair was needed at an early age due to progressive congestive heart failure. Surgical correction was performed with cardiopulmonary bypass for closure of ASD and direct anastomosis of the ALPA onto the main pulmonary artery.
