Does the modified myocardial performance index (Mod-MPI) based on valve clicks improve reproducibility compared to the previously used method in fetal cardiac evaluation?
Using Doppler echoes of valve clicks to calculate the modified myocardial performance index improves the reproducibility of fetal left cardiac function assessment.
Calculation of the Mod-MPI based on Doppler echoes of the MV and AV clicks is associated with a lower variation and better inter- and intraobserver agreement than the previously used method for fetal cardiac evaluation.
