Serial evaluation for myocardial performance in fetuses and neonates using a new Doppler index

Abstract Background: Fetal echocardiography has been used for non‐invasive evaluation of human fetal cardiac anatomy, function and hemodynamics. The Tei index, a new Doppler index known to be independent of both ventricular geometry and heart rate, has recently been applied to the evaluation of myocardial performance.
