Aim: This study aimed to characterize the pathological types, diagnosis, chromosomal abnormalities, and postnatal clinical manifestations of right and double aortic arch malformations in fetuses.
Methods: In this retrospective study, all fetuses diagnosed with right or double aortic arch anomalies for whom conventional two-dimensional echocardiography combined with spatio-temporal image correlation was performed at our tertiary referral center between December 2012 and December 2021 were included.
Results: In total, 234 fetuses with aortic arch abnormalities were identified.
Article Synopsis
- * The study involved 407 SGA infants, revealing that those with ultrasound suspicion of fetal growth restriction (FGR) had a higher chance of iatrogenic deliveries, including preterm birth and elective C-sections.
- * While ultrasound detection of FGR led to increased intervention, it did not significantly improve neonatal outcomes, except for a decrease in the need for resuscitation after birth.
Prenatal diagnosis of congenital portosystemic shunt: A single-center study.
J Obstet Gynaecol Res
October 2020
Aim: To review our experience with the prenatal diagnosis of congenital portosystemic shunt (CPSS).
Methods: This is a retrospective study of CPSS cases examined at an ultrasonographic tertiary referral center from 2013 to 2019. The anatomical origin and drainage of the shunt were assessed.
Objectives: Establish a fetal heart anatomical cross-sectional database that correlates with screening transverse ultrasound images suggested by international professional organizations to detect congenital heart defects.
Methods: Fetuses with suspected congenital heart defects identified using the following cardiac image sequences obtained from transverse slices beginning from the upper abdomen and ending in the upper thorax were the subjects of this study: (1) four-chamber view, (2) left ventricular outflow tract view, (3) three-vessel right ventricular outflow tract view, and (4) the three-vessel tracheal view. A database of digital two-dimensional images of the transverse sweep was created for fetuses with confirmed congenital heart defects.
Objective: Our aim was to evaluate the value of the volumetric fraction of vascular endothelial cells (EnVF) for determining endometrial receptivity in women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).
Materials And Methods: The records of women undergoing IVF/ICSI between 2006 and 2010 were retrospectively reviewed. An endometrial biopsy was performed in the cycle prior to IVF/ICSI.
Objective: To provide an anatomical basis for continuous transverse scanning of the fetal heart by analyzing the typical cross-sectional characteristics of different types of congenital heart deformities (CHDs) using an anatomical image database.
Materials And Methods: The database consisted of cross-sectional images obtained from 45 cases of common fetal CHDs, which were continuously displayed by the three-dimensional software Amira 5.3.
The Application of an Anatomical Database for Fetal Congenital Heart Disease.
Chin Med J (Engl)
October 2015
Background: Fetal congenital heart anomalies are the most common congenital anomalies in live births. Fetal echocardiography (FECG) is the only prenatal diagnostic approach used to detect fetal congenital heart disease (CHD). FECG is not widely used, and the antenatal diagnosis rate of CHD varies considerably.

- The study aimed to create a database containing ultrathin cross-sectional images of fetal hearts affected by various congenital heart diseases (CHDs) for clinical use.
- Forty fetal heart samples from induced labor were processed and photographed to generate detailed anatomical images, which were then imported into 3D software for further analysis.
- The resulting database allows for dynamic visualization and study of fetal heart anatomy as well as aids in education for sonographers and students, with potential for expanding the library with more cases.
