Diagnosis of fetal congenital heart disease

The most important diagnostic method for fetal congenital heart disease is a systematic ultrasound examination, commonly known as a detailed anomaly scan. This is typically performed during the second trimester, between 20 and 26 weeks of gestation, with 22-24 weeks being the optimal time for a systematic ultrasound. During this period, various malformations in different parts of the fetal body can be detected, and congenital heart disease is also screened for at this time.

Ostium primum atrial septal defect

Atrial septal defect (ASD) is a type of congenital heart disease, accounting for 30% of all congenital heart diseases. Ostium primum atrial septal defect is one type, also known as an unclosed ostium primum ASD, accounting for approximately 15%. The defect is located at the junction of the atrial septum and the endocardial cushion. It is often associated with a cleft in the anterior leaflet of the mitral valve, and occasionally with a cleft in the tricuspid valve. Compared to ostium secundum atrial septal defect, its pathophysiological changes are more severe, and the disease progresses more rapidly.
