“…Like RT3DE, STIC volumes can also be calculated automatically. Rizzo G et al reported good agreement between VOCAL and sonographic automatic volume calculation (sonoAVC) for fetal ventricular volume measurements (intraclass correlation coefficients 0.978 and 0.985 for LV and RV), and the time necessary to measure the SV was significantly shorter with sonoAVC (2.8 versus 11.7 minutes) than with VOCAL [28].…”

ObjectivesWe sought to determine the feasibility and reproducibility of real-time 3-dimensional echocardiography (RT3DE) for evaluation of cardiac volume, mass, and function and to characterize maturational changes of these measurements in human fetuses.MethodsEighty pregnant women in the 2nd and 3rd trimesters (59 with normal fetuses and 21 with fetuses with congenital heart disease [CHD]) were enrolled. We acquired RT3DE images using a matrix-array transducer. RT3DE measurements of volume, mass, stroke volume (SV), combined cardiac output (CCO), and ejection fraction (EF) were obtained. Images were scored and analyzed by two blinded independent observers. Inter- and intraobserver variabilities and correlations between fetal cardiac indices and gestational age were determined.ResultsFifty-two of 59 normal data sets (88%) and 9 of 21 CHD data sets (43%) were feasible for analysis. In normal fetuses, the right ventricle (RV) is larger than the left ventricle (LV) (P<0.05), but no difference exists between the LV and RV in mass, SV, CO, and CO/CCO. The EFs for the LV and RV were diminished; the RVSV/LVSV was reduced in CHD fetuses compared with normal fetuses (P<0.05). Fetal ventricular volumes, mass, SV, and CCO fit best into exponential curves with gestational age, but LVEF, RVEF, and RVSV/LVSV remain relatively constant.ConclusionsRT3DE is feasible and reproducible for assessment of LV and RV volume, mass, and function, especially in normal fetuses. Gestational growth of these measures, except for EF, is exponential in normal and CHD fetuses. CHD fetuses exhibit diminished LV and RV EFs.

“…A solid body of evidence suggests that 4D sonography with STIC facilitates examination of the fetal heart 3 , 4 , 5 , 11 – 37 and may also be used to evaluate fetal cardiac function 18 , 22 , 27 , 30 , 31 , 33 , 38 – 46 . This modality has also been used in the prenatal evaluation and diagnosis of congenital heart disease (CHD) 2 , 20 , 47 – 71 because it improves the ability to identify complex intracardiac relationships and can shorten the examination time 3 , 17 , 72 .…”

The effective performance of fetal cardiac examination using spatiotemporal image correlation (STIC) technology requires 2 essential steps: volume acquisition and postprocessing. An important prerequisite is training sonologists to acquire high-quality volume data sets so that when analyzed, such volumes are informative. This article is part 2 of a series on 4-dimensional sonography with STIC. Part 1 focused on STIC technology and its features, the importance of operator training/experience and acquisition of high-quality STIC volumes, factors that affect STIC volume acquisition rates, and general recommendations on performing 4D sonography with STIC. In part 2, we discuss a detailed and practical stepwise approach for STIC volume acquisition, along with methods to determine whether such volumes are appropriate for analysis.

Role of Sonographic Automatic Volume Calculation in Measuring Fetal Cardiac Ventricular Volumes Using 4-Dimensional Sonography

Abstract: There was good agreement between cardiac volumes measured with VOCAL and sonoAVC. Sonographic automatic volume calculation represents a rapid technique for estimating fetal stroke volume and promises to become the method of choice.
