Anatomically corrected malposition of the great arteries: a challenging fetal diagnosis.

Anatomically corrected malposed great arteries are uncommon and benign entity. Basically, this occurs with ventriculoarterial concordance in which the great vessels arise parallel instead of a twisting fashion. In this manuscript, we described two cases in which the antenatal diagnosis of anatomically corrected malposition of great arteries was suspected and confirmed during the postnatal period.

Evaluation of fetal heart geometry during pregnancy by three-dimensional ultrasound using the STIC rendering mode.

Objective: To determine fetal heart geometry during pregnancy using three-dimensional (3D) ultrasound and the spatiotemporal image correlation (STIC) rendering mode.

Methods: This prospective, cross-sectional study evaluated 250 normal singleton pregnancies from 20 to 33 weeks and 6 days of gestation. STIC rendering was used to calculate the eight angles of the fetal heart: apex, base, mitral valve, tricuspid valve, left ventricle, right ventricle, left atrium, and right atrium angles.

Reference Ranges of Fetal Cardiac Biometric Parameters Using Three-Dimensional Ultrasound with Spatiotemporal Image Correlation M Mode and Their Applicability in Congenital Heart Diseases.

To determine reference values for fetal heart biometric parameters using the spatiotemporal image correlation (STIC) M mode and their applicability in congenital heart diseases (CHDs). A cross-sectional prospective study was conducted with 300 singleton pregnancies between 20 and 33 + 6 weeks of gestation. Right ventricular wall thickness (RVWT), interventricular septum thickness (IVST), and left ventricular wall thickness (LVWT) were measured off-line using the STIC-M mode with the cursor perpendicular to the interventricular septum.
