METHODS:
Data were collected for patients undergoing first-time mitral valve
surgery for ischemic mitral regurgitation between 1990 and 2009 (n =
393). Patients who underwent combined procedures for papillary muscle
rupture, post-infarction ventricular septal defect, endocarditis, or any
previous cardiac surgery were excluded. Preoperative demographics,
operative variables, and hospital outcomes were analyzed, and
multivariable regression analysis was employed to identify independent
predictors of hospital mortality.
