Key result
Raising the wall motion filter provided the best reproducibility (ICC 0.94) for fetal left myocardial performance index compared to baseline settings (ICC 0.81).

Does changing ultrasound settings or equipment affect the calculation and repeatability of fetal left myocardial performance index?
Population
62 fetuses (28-36 weeks of gestational age)
Comparison
Different ultrasound settings and two different… vs Baseline settings

Optimizing wall motion filter may enhance fetal left MPI consistency; supports standardization yet leaves optimal protocols open for prospective study.

Does changing ultrasound settings or equipment affect the calculation and repeatability of fetal left myocardial performance index?
Strict standardization of ultrasound settings and equipment is necessary to decrease variability and improve reproducibility of fetal left myocardial performance index measurements.
Lobmaier et al. (2014) conducted an observational in Fetal cardiac function assessment (n=62). Different ultrasound settings (sweep speed, gain, wall motion filter) and equipment vs. Baseline settings was evaluated on Left myocardial performance index (MPI) values and reproducibility (Intraclass coefficients of agreement). Raising the wall motion filter provided the best reproducibility (ICC 0.94) for fetal left myocardial performance index compared to baseline settings (ICC 0.81).
