Abstract
- A 12-day-old female baby underwent a Norwood procedure for hypoplastic left heart syndrome. The left superior vena cava (LSVC), which was found incidentally during the operation, was divided to facilitate surgical exposure. After the operation, she developed signs of low cardiac output and died 7 hours afterward. Autopsy findings showed that the coronary sinus was atretic at the orifice without unroofing into both atria, rendering the LSVC the sole route of coronary sinus drainage. In patients with incidentally-found LSVC during surgery, special care should be taken to leave the LSVC intact because the LSVC may be the exclusive drainage vein of the coronary venous system.
