Article Synopsis
  • * The study utilized advanced imaging techniques like 2D echocardiography and 3DSTE to measure various heart function parameters, revealing that parameters such as twist and myocardial performance index are generally better in the TA group.
  • * Blood flow patterns differ significantly between SLV and TA, with SLV exhibiting disorganized flow and incomplete vortex formation, indicating more severe functional impairments in those patients.

Secundum atrial septal defect (ASD) is one of the most common congenital heart diseases (CHDs). This study aims to evaluate the feasibility and accuracy of automatic detection of ASD in children based on color Doppler echocardiographic images using convolutional neural networks. In this study, we propose a fully automatic detection system for ASD, which includes three stages.

Background: Fetal right atrium (RA) dilation is frequently detected in routine screenings while it remains a challenge to clarify the reasons. This study aimed to analyze the cardiac anatomy and hemodynamics of fetal RA dilation and the changes of hemodynamic indexes.

Methods: In the retrospective study, 420 fetuses with RA dilation were included, which were classified into the physiological group (n = 202), volume overload group (n = 142), and the pressure overload group (n = 76).

In utero diagnosis of anomalous origin of one pulmonary artery from the ascending aorta (AOPA) has been rarely reported, although this malformation has a high mortality rate due to the rapid development of pulmonary hypertension. We report two cases of AOPA, in which either the left or the right pulmonary artery originated from the distal part of the ascending aorta. Scanning around the three-vessel view to search for the origin of the left and right pulmonary arteries is essential for the diagnosis.

Coronary artery fistula (CAF) is a rare malformation and is seldom reported during pregnancy. Right coronary artery fistula commonly drains into the right ventricle, right atrium, or pulmonary artery. We describe here a rare case of fetal CAF draining into the left ventricle using cross-sectional and color Doppler echocardiography.
