Delayed sternal closure is a life saving decision.

Nineteen hundred and fifty open heart operations were performed between January 1995 and December 2000 at the cardiac surgery department of Chest Disease Hospital in Kuwait. Sternal closure was delayed in 40 patients (2%), because of hemodynamic instability limiting primary closure in 23 patients and uncontrollable bleeding in 17 patients. Four patients died in the immediate postoperative period while the chest was open, due to persistent low cardiac output secondary to myocardial failure.
