Aortic root replacement with absent left-main coronary artery: how to do it.

Aortic root replacement in patient with a coronary artery anomaly can be challenging.

There were separate origins of the left anterior descending and left circumflex coronary arteries from the aorta. The technical modification employed in this case is discussed.
