Coronary Artery Bypass for Acute Latrogenic Ostial Injuries

Acute injury to coronary ostia during aortic valve replacement is nearly universally fatal. Early recognition and prompt correction by saphenous vein bypass graft prevented mortality from this technical error. Borrowing from experience with bypass grafts used for coronary obstructive disease, a modification of the aorta-saphenous vein graft anastomosis is described. Avoidance of ostial injury is best accomplished by avoiding instrumentation of cannulation of the coronary artery. The use of local deep cardiac hypothermia using cold saline solution protects the myocardium and the coronaries should not be perfused.
