To assess the incidence, pathophysiology and influence on operative outcome of a depressed left ventricular (LV) ejection fraction (EF) in patients with mitral stenosis (MS), demographic, hemodynamic and cineangiographic data on 72 patients (16 men, 56 women, aged 19 to 75 years) with isolated MS were reviewed. 0f the 45 who had mitral commissurotomy or replacement, operative course and functional class before and after surgery were assessed. Of the 72 patients, 21(29%) had an LVEF 50.50. These 21 were similar to the 51 with an LVEF >0.50 in age, gender, heart rate, intracardiac pressures, transvalvular gradient and valve area, but they had larger LV end-diastolic (79 ± 19 [mean ± SD] vs 59 ± 15 ml/m2, p 2, p .0.50.
