摘　　要：Background: Left ventricular size is a factor independently associated with increased mortality in mitral surgery, particularly, in the setting of ischemic mitral regurgitation (IMR). In some patients with dilated ventricles, reverse remodelling does not occur, with a high risk of residual or recurrent mitral regurgitation and therefore associated with worse outcome. We conducted multi-centers retrospective observational study on a cohort of patients who had combined CABG and mitral surgery for moderately severe IMR to correlate a relationship between perioperative left ventricular dimensions to postoperative mortality rates in both genders. Results: 287 patients had combined CABG and mitral valve surgery. The exclusion criteria were patients with very low function Conclusion: Failure of early ventricular remodeling with persistently elevated end systolic dimensions is a risk factor for postoperative death in both genders. Females gender will have an additional higher risk if the end diastolic dimensions remain elevated.Background: Left ventricular size is a factor independently associated with increased mortality in mitral surgery, particularly, in the setting of ischemic mitral regurgitation (IMR).
