Reconstruction of the Anomalous Left Coronary Artery Within the Main Pulmonary Artery

Successful reconstruction of the anomalous origin of the left coronary artery from the pulmonary artery was performed in a 27-year-old man. A patch of glutaraldehyde-treated bovine pericardium was used to construct a tunnel within the main pulmonary artery, connecting a created aortopulmonary window to the ostium of the left coronary artery. Angiography one month after the operation demonstrated patency of the tunnel. The procedure is suitable when direct re-implantation of the left coronary artery into the aorta is impossible for technical reasons.
