Objective: The purpose of this study is to establish a new reference range for fetal interventricular septal thickness in uncomplicated pregnancy at 28-37 weeks of gestation. Materials and Methodology: This was a prospective cross sectional study involving 300 singleton pregnancies between 28-37 weeks of gestation without any known risk factors of adverse pregnancy outcome who were referred for routine obstetric examination. The protocol included the prenatal 2-dimensional M-mode echocardiographic measurements of fetal IVST and data were used to construct the normograms and percentile fitted curves for different gestational age. The relationship between the IVSD and IVSS and gestational age were determined. Results: A total of 300 measurements were obtained. The normal values of the IVSD and IVSS according to gestational age were presented as 5 th , 50 th and 95 th percentile ranks. The correlation coefficients (r) between the IVSD and IVSS and gestational age were 0.19 and 0.14, respectively. The weak correlation may be probably due to small sample size. The IVSD and IVSS were not statistically different with advancing gestation. The 95 th percentile of the IVSD was 4.57 millimeters (mm) (range =4.12 to 4.62 mm) and IVSS was 6.67 mm (range = 5.81 to 6.77 mm). Conclusion: The normal values of fetal IVSD and IVSS in a Nepalese population from 28 to 37 weeks' gestation were established. This could be used as a baseline data in detecting the asymmetrical septal hypertrophy during fetal life.

“…14 A total of 300 pregnant women completed the study, 292 had both early and follow up anatomy scans while 8 cases with confirmed lethal anomalies by early scan chose to terminate their pregnancies and the anomalies were confirmed after termination. 15 The incidence of anomaly in our study was 3.67%. We found anomalies were more in advanced age group women in our study (p<0.001).…”

Background: Congenital anomalies are one of the leading causes of infant mortality. Traditional TIFFA scan done at 18-22 weeks leads to delay in diagnosis, referral and management. With high resolution ultrasound and TVS probe, normal and abnormal fetal anatomy could be visualized in early gestation with good accuracy. Objective of present study was to evaluate the efficacy of 11-13+6 weeks anatomy scan in detecting fetal structural anomalies compared to traditional 18 -22weeks scan and in visualizing the complete normal fetal anatomyMethods: An Observational study of 300 antenatal patients at Jubilee Mission Medical College for 1 year (Jan-Dec2014) was done. The scan was performed at 11-13+6 weeks by TAS first, if a full fetal anatomy survey not achieved, TVS added. A mid-trimester fetal anatomy scan was then performed in patients who had not dropped out, miscarried or undergone pregnancy termination at 18-22weeks.Results: The incidence of anomalies in our study was 3.67% -11 cases; 9 detected at 11-13+6 weeks, 2 were newly detected at 18-22 weeks. At 11-13+6 weeks anatomy scan, the detection rate of anomalies was 81.8% and complete fetal anatomy survey was achieved in 92%. Heart and kidneys were not properly visualized in 4% and 12.7%, at 11‐13+6 weeks compared with 0.7% and 0% at 18‐22 weeks.Conclusions: The 11-13+6 weeks anatomy scan is an important diagnostic tool which is underutilized and should be offered to all women as a routine standard of antenatal care. However as fetal anomalies can present at varying gestational age, standard 18-22 weeks anatomy scan cannot be abandoned.

“…Maternal obesity is associated with less complete anatomical surveys, increased number of scans required, decreased detection of fetal anomalies and limitation of the visualization of the fetal organs Hendler 2005;Dashe 2009;Thornburg 2009;Aagaard-Tillery 2010;Maxwell 2010). The findings that are of importance for the parents are, of course, those indicating the presence of lethal anomalies and even other anomalies that have the potential for causing future severe handicap in the child.…”

“…The need for continuous education is recognized as an important factor in ensuring effective screening that in principle is made possible by the improved resolution of the ultrasound image (Ogge 2006;McBrien 2010). The influence of obesity on diagnostic performance has not been studied extensively, but the rate of completed examinations was lower in the group with maternal obesity than in the other groups Hendler 2005;Thornburg 2009;Maxwell 2010). The influence of maternal obesity on ultrasound detection of fetal anomalies has been studied by Dashe et al (N=10,112) and Aagaard-Tillery et al (N=8,555) in two low-risk US populations (Dashe 2009;Aagaard-Tillery 2010).…”

Suboptimal Second-Trimester Ultrasonographic Visualization of the Fetal Heart in Obese Women

Abstract: Repeated ultrasound examination for SUV of the fetal heart at a later gestational age dramatically reduces SUV. However, obese patients continue to have much higher rates of persistent SUV.
