Conclusion
Our results suggest that hospital mortality after surgery for ischemic
mitral regurgitation is determined mostly by the patient’s risk profile
rather than the choice of valve repair or replacement. Valve repair may
reduce the risk of postoperative low cardiac output syndrome. However,
the decision to repair or replace the valve should consider the
preoperative risk profile and physiological reserve of each patient as
well as the surgeon’s experience in mitral valve repair.
