Implication

Establishes normative fetal Tei Index values for myocardial assessment; leaves open prospective validation before guiding clinical decisions.

Structured PICO

What are the normal values of the fetal left ventricular Tei Index in second- and early third-trimester fetuses?

P
Population
74 second- and early third-trimester fetuses (18-31 weeks' gestation)
I
Intervention
Doppler myocardial performance index (Tei Index) measurement
O
Outcome
Normal values of fetal left ventricular (LV) Tei Indexsurrogate

The Tei Index is a feasible, non-invasive Doppler-derived tool for assessing fetal myocardial function, with a normal value of 0.53 +/- 0.13 in the second and early third trimesters.
