  • Right ventricular myocardial performance index predicts perioperative mortality or circulatory failure in high-risk valvular surgery JOURNAL OF THE AMERICAN SOCIETY OF ECHOCARDIOGRAPHY Haddad, F., Denault, A.

    The prognostic value of right ventricular myocardial performance index (RVMPI) and right ventricular fractional area change (RVFAC) in mitral or aortic valve surgery has not been well described. The main objective of this study is to assess the prognostic value of RVMPI and RVFAC in predicting postoperative mortality or circulatory failure.RVMPI and RVFAC were prospectively measured after induction of anesthesia using transesophageal echocardiography in 50 consecutive patients undergoing corrective mitral or aortic valve surgery. Univariate and multivariate analyses were performed for the primary clinical end point of in-hospital mortality or circulatory failure.In the study population, the mean age was 67 +/- 9 years. The primary end point occurred in 17 patients (34%); three patients died, and 14 patients presented signs of circulatory failure. Multivariate regression analysis identified RVMPI and RVFAC as variables of prognostic significance.Preoperative RVMPI and RVFAC could have an incremental value in predicting postoperative mortality and morbidity in valvular heart surgery. Future studies are needed to validate these results in a larger population.
