Anomalous left coronary artery from pulmonary artery. An eight year angiographic follow-up after saphenous vein bypass graft.

We have presented a 7-week and 8-year postoperative angiographic follow-up of a 36-year-old man who had an anomalous left coronary artery arising from the pulmonary artery and who had an aortocornary bypass graft to the left anterior descending artery. The late study showed 1) a large, well functioning patent graft, 2) lack of significant postoperative change in the size of the right coronary artery and 3) new collateral vessels between the distal left anterior descending and left circumflex coronary arteries and persistence of collateral vessels between the distal right and left circulflex coronary arteries. This report is the longest known angiographic follow-up of a patient with this anomaly who has been treated with bypass surgery.
