Normal Reference Ranges from 11 to 41 Weeks’ Gestation of Fetal Left Modified Myocardial Performance Index by Conventional Doppler with the Use of Stringent Criteria for Delimitation of the Time Periods

<b><i>Objective:</i></b> To establish normal reference intervals of the fetal left modified myocardial performance index (MPI) with the use of stringent criteria for delimitation of the time periods. <b><i>Study Design:</i></b> A cohort of consecutive singleton fetuses was created including at least 20 fetuses for each completed week of gestation between 11 and 41 weeks. The isovolumetric...
