abstract background: right ventricular myocardial performance index (rvmpi) is a doppler–derived parameter of non-geometrical ventricular function that measures both systolic and diastolic functions of the right ventricle. the aim of this study is to compare prognostic value of rvmpi with global rv function in patients undergoing coronary artery bypass graft (cabg). methods: in a longitudinal s...

background: longer survival after the total repair of the tetralogy of fallot increases the importance of late complications such as right ventricular dysfunction. this is a prospective study of the right ventricular function in totally corrected tetralogy of fallot patients versus healthy children. methods: thirty-two healthy children were prospectively compared with 30 totally corrected tetra...

Background: Assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. Ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. Objective: A myocardial performance index (MPI) or Tei index has been developed for adult...

background: diabetes mellitus is capable of impairing the myocardial function. several studies have documented the influential impact of diabetes mellitus on the left ventricular function. the right ventricular function plays a significant role in the overall myocardial contractility; hence, this study was undertaken to evaluate the effect of diabetes mellitus type ii on the right ventricular f...

Doppler-derived myocardial performance index (MPI) , defined as the s um of isovolumetric contraction and relaxation durations divided by ejection time, is an easily measured and reproducible index that shows both systolic and diastolic myocardial function. The goal of this study was to define normal values of right ventricular MPI in neonates in the first 48 to 72 hours of life. Fifty-one...
