Anomalous origin of left pulmonary artery from the aorta with partial anomalous pulmonary venous return.

Anomalous origin of left pulmonary artery (AOLPA) from the aorta is a rare congenital cardiac malformation. We report a case of AOLPA from the aorta with partial anomalous pulmonary venous return (PAPVR) in a 3.2 kg infant. Surgical correction was performed with direct anastomosis of AOLPA to the main pulmonary artery with subsequent baffling of the anomalous right pulmonary veins to the left atrium and patch augmentation of the left pulmonary artery performed at 1-month of life. Recurrent stenosis of the proximal left pulmonary artery was treated with stent placement at 17-months. Pulmonary hypertension has persisted at 30-month follow up.
