Drainage of the Left Hepatic Vein into the Coronary Sinus, a Rare Intraoperative Finding.

ABSTRACT

In a 76-year-old female undergoing coronary artery bypass surgery, a persistent left hepatic vein was observed. Draining of this vein into the coronary sinus is an extremely rare embryological malformation and this is the first case to be reported as a solitary malformation in absence of other cardiac malformations.
