The fetal ventricular size does not normally enlarge as the head grows. I know this is counter intuitive, but true. The ventricles reach their normal size in the 2nd trimester (mid pregnancy) and the brain and head continue to grow, but the ventricles remain about the same size in normal cases. Your concern that "My question is, {God forbid} is there a chance that this will grow along with pregnancy. We are very very scared, so please advice accordingly" is logical, but not the way normal ventricles grow. Here is an article that addresses this issue. I have always wondered why this is, it does not seem logical, but that is the way it is in normal pregnancies. Good luck with the pregnancy. Terry 1: J Ultrasound Med. 2003 Jan;22(1):39-43 Department of Obstetrics and Gynecology, Lis Maternity Hospital, Tel-Aviv Sourasky Medical Center, Sackler Faculty of Medicine, Tel-Aviv University, Tel-Aviv, Israel. OBJECTIVE: The upper limit of the fetal atrial width in normal fetuses is debated. This was a prospective cohort evaluation of the lateral ventricular width with special regard to the upper limit of its size. METHODS: Measurements of fetal atrial ventricular size were obtained by abdominal ultrasonography in 427 male and female fetuses between 20 and 40 weeks' gestation of normal singleton pregnancies. In addition, reanalysis of previous data (8 studies) and the current data was performed to produce a pooled mean and SD. RESULTS: The mean ventricular width +/- SD was 6.2 +/- 1.2 mm. The ventricular width did not show significant modification throughout gestation. Reanalysis of the current and previous studies (8216 cases) yielded a pooled mean of 6.4 +/- 1.2. CONCLUSIONS: According to the current and previous studies, the upper cutoff of fetal ventricular atrium width should be 10 mm. This cutoff represents a range of approximately 3 SDs above the pooled mean, corresponding to a 99.74% confidence interval. PMID: 12523609 [PubMed - indexed for MEDLINE]

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
