Refluxo Mitral antes e depois da correção

Prediction of left ventricular ejection fraction 6 months after surgical correction of organic mitral regurgitation: the value of exercise echocardiography and deformation imaging

.

Global longitudinal strain (GLS) at rest (R= −0.42, P= 0.011) and during exercise (R= −0.36, P= 0.034) correlated with postoperative LVEF. When normalized for LV end-systolic diameter, GLS during exercise was more closely correlated with postoperative LVEF and was its best predictor based on a multivariate linear regression model. At a cut-off of −5.7%/cm, sensitivity was 0.83, specificity 0.70, negative predictive value 0.64, and positive predictive value 0.86 for predicting a 6-month postoperative LVEF of <50%.

Conclusion In patients undergoing surgery for severe organic MR, GLS normalized for LV end-systolic diameter at submaximal exercise may be used as a predictor of postoperative LVEF.
