Doppler-Derived Myocardial Performance Index in Healthy Children in Shiraz
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...

متن کامل"doppler-derived right ventricular myocardial performance index in neonates: normal values "
doppler-derived myocardial performance index (mpi), defined as the sum 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 (rv) mpi in neonates in the first 48 to 72 hours of life. fifty-one q...
متن کاملDoppler-derived myocardial systolic strain rate is a strong index of left ventricular contractility.
BACKGROUND Myocardial fiber strain is directly related to left ventricular (LV) contractility. Strain rate can be estimated as the spatial derivative of velocities (dV/ds) obtained by tissue Doppler echocardiography (TDE). The purposes of the study were (1) to determine whether TDE-derived strain rate may be used as a noninvasive, quantitative index of contractility and (2) to compare the relat...
