“…In a study by Figueroa et al, 16 fetuses of diabetic mothers with polyhydramnios had a significantly higher MPI than fetuses of diabetic mothers without polyhydramnios (0.49 ± 0.08 vs 0.41 ± 0.05, P < .0001) 16 . Gezer et al 17 and Akkaya et al 18 investigated fetal MPI in pregnancies with idiopathic polyhydramnios. Table 5 summarizes the main results of those two studies together with our findings.…”

“…However, there was a significant increase in MPI of the left and right ventricles, as well as left IVCT in this patient group. Few published studies have evaluated MPI in pregnancies with idiopathic or secondary polyhydramnios 16‐18 . In a study by Figueroa et al, 16 fetuses of diabetic mothers with polyhydramnios had a significantly higher MPI than fetuses of diabetic mothers without polyhydramnios (0.49 ± 0.08 vs 0.41 ± 0.05, P < .0001) 16 .…”

PurposeTo evaluate modified myocardial performance index (MPI), or Tei index, in fetuses of pregnancies with idiopathic mildly increased amniotic fluid index (AFI).MethodsWe studied 25 cases (24‐40 weeks) with idiopathic mildly increased AFI, and 25 gestational age‐ and fetal gender‐matched healthy controls. Fetal echocardiographic variables and Doppler‐derived indices were recorded, including left and right MPI, left isovolumetric contraction time (IVCT), left ejection time (ET), left isovolumetric relaxation time (IVRT), aortic and pulmonary arterial peak systolic velocity (PSV), left and right E/A ratios, middle cerebral artery (MCA) pulsatility index (PI), and umbilical artery (UA) PI.ResultsThe mean left MPI (0.52 vs 0.41, P < .0001) and right MPI (0.50 vs 0.42, P < .001) were higher, and mean IVCT (37.7 vs 25.9, P < .0001) was longer in cases than in controls. However, there were no significant differences between the two groups in IVRT (45.2 vs 43.2, P = .381), ET (160.2 vs 170.0, P = .079), aortic PSV (P = .073), left E/A (P = .080), pulmonary artery PSV (P = .061), right E/A (P = .054), MCA PI (P = .259), UA PI (P = .685), and cerebroplacental ratio (P = .645).ConclusionPregnancies with idiopathic mildly increased AFI were associated with a significant increase in the fetal MPI of both left and right ventricles.

ObjectiveThis study will evaluate whether fetal cerebroplacental ratio (CPR) can predict perinatal adverse outcomes in singleton pregnancies with mild and moderate idiopathic polyhydramnios (IP).MethodThis study was designed as a prospective case–control study between January 2023 and November 2023. Pregnant women diagnosed with mild‐to‐moderate IP and low‐risk singleton pregnancies were included in the study. In all cases, umbilical artery (UA) and middle cerebral artery (MCA) pulsatility indices (PIs) were measured at 36–40 weeks of gestation, and CPR was calculated. The group with polyhydramnios was divided into two parts according to whether the CPR value was below 1.08 or 1.08 and above. Perinatal outcomes of all groups were compared.ResultsA total of 140 patients were included in the study. Seventy of these were IP cases, and 70 were low‐risk pregnant women. UA PI in the IP group was not statistically different from that in the low‐risk group, but MCA PI and CPR were significantly lower in the IP group (P = 0.07, P = 0.001, and P = 0.004, respectively). IP cases were divided into a low group (<1.08, n = 18) and a normal group (≥1.08, n = 52) according to the CPR value. Cesarean section rates due to fetal distress were significantly higher in the low‐CPR group (n = 8 [44.4%] vs 5 [9.6%], P = 0.001). In the low‐CPR group, 5‐min Apgar <7, and neonatal intensive care unit (NICU) admission rates were significantly higher (P = 0.045 and P = 0.001, respectively).ConclusionIt is encouraging that in cases with mild‐to‐moderate IP, low CPR predicts emergency delivery due to fetal distress, a low Apgar score at 5 min, and NICU admission.

Objective This study aimed to evaluate fetal epicardial fat thickness (EFT) along with fetal myocardial performance index (MPI) and its effects on perinatal outcomes in non‐severe idiopathic polyhydramnios (IP). Materials and Methods This prospective study included 92 participants, 32 diagnosed with non‐severe IP, and 60 healthy pregnant women. Amniotic fluid indices (AFI), umbilical and middle cerebral artery Doppler, EFT, and MPI measurements were performed for all patients. Results The fetal EFT and MPI values were statistically higher in the non‐severe IP group than in the control group (p = 0.0001, p = 0.014, respectively). The optimal fetal EFT cutoff value for predicting non‐severe IP disease was found as 1.3 mm with a specificity of 81.7% and sensitivity of 59.4%. The EFT cutoff for predicting cesarean section in non‐severe IP cases was 1.25 mm (p = 0.038). Apgar scores, neonatal intensive care unit, respiratory distress syndrome, and stillbirth rates were not different between groups. Conclusion In this study, EFT and MPI were found to be higher in non‐severe IP cases compared to controls. It was observed that the increase in MPI and EFT was associated with the increase in cesarean rates, but not with adverse fetal outcomes.
