Evaluation of the Fetal Myocardial Performance Index in Abnormal Cardiotocography Cases in 3rd Trimester of Pregnancy and Fetal Outcome

Abstract

Cardiotocography (CTG) monitoring is widely used to assess fetal wellbeing. There is no evidence to suggest that monitoring women with high-risk pregnancies benefits the mother or baby. Fetal echocardiography has been used for non-invasive evaluation of human fetal cardiac anatomy, function and haemodynamics. The myocardial performance index (MPI) has been proposed as a potential useful predictor of global cardiac function. MPI or the Tei index is defined as the sum of the isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) divided by ejection time (ET). The equation of the MPI is thus (ICT + IRT)/ET. To improve reproducibility. The best prenatal screening method of mothers in late pregnancies remains elusive. Umbilical artery (UA) Doppler velocimetry is widely used to monitor high-risk pregnancies; however, it has not been shown to be an effective test of fetal well-being in diabetic pregnancies. Similarly, the efficacy of ductus venosus Doppler velocimetry for monitoring fetuses of diabetic pregnancies is unsatisfactory. Impaired cardiac function in fetuses in the third trimesters is well documented. Increased myocardial performance index suggesting impairment of global myocardial
