“…Stroke volumes of the ventricles have a curvilinear relationship with gestational age [6] and it seems that the relative high stroke volume of the most immature fetus is explained by increased myocardial deformation. These observations are in agreement with other studies demonstrating declining ejection fractions with advancing gestational age [7,8].…”

BackgroundPresent data regarding how the fetal heart works and develops throughout gestation is limited. However, the possibility to analyze the myocardial velocity profile provides new possibilities to gain further knowledge in this area. Thus, the objective of this study was to evaluate human fetal myocardial characteristics and deformation properties using color-coded tissue velocity imaging (TVI).MethodsTVI recordings from 55 healthy fetuses, at 18 to 42 weeks of gestation, were acquired at a frame rate of 201–273 frames/s for offline analysis using software enabling retrieval of the myocardial velocity curve and 2D anatomical information. The measurements were taken from an apical four-chamber view, and the acquired data was correlated using regression analysis.ResultsLeft ventricular length and width increased uniformly with gestational age. Atrioventricular plane displacement and the E’/A’ ratio also increased with gestational age, while a longitudinal shortening was demonstrated.ConclusionsFetal cardiac muscle contractility decreases with gestational age. As numerous fetal- and pregnancy-associated conditions directly influence the pumping function of the fetal heart, we believe that this new insight into the physiology of the human fetal cardiovascular system could contribute to make diagnosis and risk assessment easier and more accurate.

“…Through this application, mean stroke volume was found to range from 0.78 cm 3 at midgestation to 5.5 cm 3 at term, whereas the ejection fraction remained fairly stable through gestation (Messing et al 2007 (Molina et al 2008). An exponential increase in stroke volume and cardiac output was observed, whereas ejection fraction remained nearly constant (Simioni et al 2011). To compare 2-DUS and 3-DUS echocardiography, Tonni et al (2009) assessed the feasibility of including volumetric 3-D reconstruction of cardiac anatomy and Doppler angiography of the major vessels in routine second-trimester pregnancy scans in a low-risk pregnancy population.…”

“…With respect to cardiac evaluation at STIC, first study was performed by Messing et al [13], who evaluated the volume of the ventricular chambers in both systole and diastole in 100 fetuses using methods Virtual Organ Computer-aided Analysis (VOCAL) associated with the inversion mode. Later, other authors also evaluated fetal cardiac function and Molina et al [14] who used the STIC associated only with VOCAL, Uittenbogaard et al [15] who used the STIC and 3D slice method and, more recently, Simioni et al [16] and Hamill et al [17], using only the VOCAL associated with STIC. However, no studies comparing cardiac function by means of 3D U.S. with STIC in relation to gender.…”

Débito cardíaco e fração de ejeção fetal por meio do spatio-temporal image correlation (STIC): comparação entre fetos masculinos e femininosFetal cardiac output and ejection fraction by spatio-temporal image correlation (STIC): comparison between male and female fetuses Abstract Objective: To compare the cardiac output (CO) and ejection fraction (EF) of the heart of male and female fetuses obtained by 3D-ultrasonography using spatio-temporal image correlation (STIC).Methods: We conducted a cross-sectional study with 216 normal fetuses, between 20 and 34 weeks of gestation, 108 male and 108 female. Ventricular volumes at the end of systole and diastole were obtained by STIC, and the volumetric assessments performed by the virtual organ computer-aided analysis (VOCAL) rotated 30°. To calculate the DC used the formula: DC = stroke volume / fetal heart rate, while for the FE used the formula: EF = stroke volume / end-diastolic volume. The DC (combined male and female) and EF (male and female) were compared using the unpaired t test and ANCOVA. Scatter plots were created with the percentiles 5, 50 and 95.Results: Rev Bras Cir Cardiovasc 2012;27(2):275-82

Heart stroke volume, cardiac output, and ejection fraction in 265 normal fetus in the second half of gestation assessed by 4D ultrasound using spatio-temporal image correlation

Abstract: Four-dimensional ultrasound using STIC represents a simple and reproducible method for estimating fetal cardiac function. STIC seems to overcome many of the pitfalls of conventional ultrasound methods and has the potential to become the method of choice.
