Abstract:

Objective

To investigate the echocardiographic features and clinical significance of prenatal diagnosis of aortopulmonary septal defect (APSD).

Methods

Images of 4 cases of APSD diagnosed by fetal echocardiography during January 2008 to December 2017 in the affiliated Suzhou hospital of Nanjing medical university were reviewed. Echocardiographic features and clinical significance of prenatal diagnosis of APSD were summarized.

Results

The key feature of prenatal diagnosis of APSD was the demonstration of a connection between the ascending aorta and main pulmonary artery. The defect could be best identified on the three-vessel view, three-vessel and trachea view and short axis view of great arteries. Flow across the defect could be bidirectional, left-to-right or right-to-left. Dilated ascending aorta may be seen as an indirect sign of APSD. All the 4 cases were associated with other cardiac anomalies, including 1 case of Berry syndrome. One case was associated with extracardiac abnormalities.

Conclusions

There are fetal echocardiographic features of APSD. Berry syndrome, which was commonly associated with genetic anomaly, should be suspected when distal type APSD was found. Prenatal diagnosis of APSD is feasible and essential as a surgical correction early after birth can improve the prognosis.
