Left ventricular (LV) end-systolic diameter and LV ejection fraction (LVEF) are correlated with postoperative LVEF and prognosis in patients with organic mitral regurgitation (MR). However, in some patients, the LVEF does not return to normal 6 months postoperatively, despite normal preoperative diameters. Thus, our study aimed to evaluate whether preoperative LV strain values assessed by echocardiography at rest and during exercise were predictors of postoperative LVEF at 6-month follow-up in patients undergoing surgery for severe organic MR.
