Predictors of preserved left ventricular systolic function after surgery for chronic organic mitral regurgitation: a prospective study.

Abstract

Among patients with chronic severe MR, the preoperative LVESVI best correlated with the three-month postoperative LVEF. A preoperative effective forward LVEF < 0.40 accurately predicted a depressed postoperative LVEE. Over the succeeding two years, there will be ongoing positive LV remodeling. If confirmed in a larger series, the effective forward LVEF may serve as a useful clinical guide for the timing of corrective surgery in this population.
