Isolated left hepatic vein draining into the coronary sinus: a rare anomaly encountered during mitral valve surgery.

ABSTRACT

A left hepatic vein draining into the coronary sinus is an extremely rare congenital abnormality as a solitary cardiovascular malformation. We encountered the anomaly during the mitral valve surgery in a 72-year-old woman. The operation was successfully carried out using an additional suction directly in the left hepatic vein.
