Does right ventricular function impairment predict postoperative survival in patients with organic mitral regurgitation referred to surgery?
Preoperative right ventricular and biventricular impairment are significant predictors of postoperative mortality in patients undergoing surgery for organic mitral regurgitation.
In patients with organic mitral regurgitation referred to surgery, RV function impairment is frequent (30%) and depends weakly on pulmonary artery systolic pressure but mainly on left ventricular remodeling and septal function. RV function is a predictor of postoperative cardiovascular survival, whereas biventricular impairment is a powerful predictor of both cardiovascular and overall survival.
