It is an index that incorporates both systolic and diastolic time intervals in expressing global systolic and diastolic ventricular function. As the result of its complex geometry and position, characterization of rv function by 2dimensional echocardiography has remained a challenge since the initial measurements of rv volumes and dimensions in 1979.

Fetal echocardiography with doppler was performed at admission for the preterm prom group, with serial examinations every 710 days thereafter until delivery, and at the time of inclusion in the control group. The objective of this study, therefore, was to examine, in patients with prom at less than 34 weeks of gestation, the relationship between myocardial performance measured by the tei index and firs.
