THE FETAL CIRCULATION The two lower chambers are known as the ventricles and the two upper chambers are the atria. Conclusions: Fetal tricuspid valve regurgitation with normal heart anatomy was a frequent finding during indicated fetal echocardiographic examination and may indicate abnormal physiologic characteristics (increased preload or afterload, myocardial impairment, or arrhythmia). The wall dividing the two atria is called the atrial septum. Normal fetal anatomy. Complete examination of the fetal heart in the first trimester can be challenging due to the smaller size. normal sonographic anatomy The systematic visualization of the fetal chest in the first trimester is generally achieved from multiple sonographic planes.

A fetal pericardial effusion is typically seen as anechoic fluid component greater than 2 mm surrounding the heart (similar to adults), which may be demonstrated by B-mode or M-mode ultrasonography. Once a baby is born however, it must begin to function with a circulatory system that resembles […] It is measurable sonographically from around 6 weeks and the normal range varies during gestation, increasing to around 170 bpm at 10 weeks and decreasing from then to … EKuske. There is also a slow deceleration in fetal heart rate in the last ten weeks of pregnancy. Although normal ranges for the fetal ventricular system in the first trimester are available, mild ventriculomegaly may still be a normal variant. Case Study – A Tiny Heart. The range of normal anatomy was analyzed by review of fetal MR examinations performed at the Beth Israel Deaconess Medical Center between 1995 and 2000. RA= right atrium, LA= left atrium, LV= left ventricle, RV= right ventricle. Normal Fetal Cardiac Anatomy. Typically, the PFO closes shortly after birth because it is no longer needed. Cardiac Axis.
