OC004: Fetal cardiac output determination by four-dimensional fetal echocardiography using spatiotemporal image correlation (STIC) and VOCAL™

Fetal cardiac output and ejection fraction by spatio-temporal image correlation (STIC): comparison between male and female fetuses.

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...

Fetal cardiac function: M-mode and 4D spatiotemporal image correlation.

Fetal cardiac function has been shown to be a marker of disease severity in many conditions, including intrauterine growth restriction, congenital heart defects or disease (CHD), twin-to-twin transfusion syndrome, idiopathic hydrops, fetal arrhythmias, and others. It is often targeted for evaluation of patient management, for providing complete and accurate diagnoses in CHD, for patient counsel...

New Insight from Using Spatiotemporal Image Correlation in Prenatal Screening of Fetal Conotruncal Defects

Three- and four-dimensional fetal echocardiography.

The rapid continuing development of 3-dimensional ultrasound imaging technologies has extended capabilities of fetal cardiac scanning beyond 2-dimensional imaging technologies and now provides a wide array of analytic possibilities. The acquisition of the 3D volume information is based on initial application of 2-dimensional imaging techniques including grey scale, Doppler, Power Doppler and B-...

Comparison of Fetal Echocardiography for Fetal Cardiac Structure in Women with Gestational Diabetes Mellitus and Normal Pregnancies

BackgroundIncreased metabolic rate of hyperglycemia in gestational diabetes causes macrosomia, which can also affect the fetal heart. The thickness of the walls of the heart and its function in women with gestational diabetes mellitus (GDM) can change over time before treatment. We aimed to evaluate fetal cardiac structure in terms of ventricular wall thickness and its function in women w...
