Abstract:

Objective

To investigate the prenatal echocardiography manifestation of aortopulmonary septal defect (APSD) and clinical significance.

Methods

Imaging characteristics for 5 fetuses with APSD who underwent fetal echocardiography at our hospital from June 2013 to November 2015 were retrospectively reviewed. All cases were followed up for pregnancy process and clinical results.

Results

Echocardiographic characteristics of APSD were a defect between the ascending aorta and the trunk of the pulmonary artery in the three vessels view. The defect sizes were ranged from 1.5 to 3.9 mm. The defect location to semilunar valve and /or pulmonary artery bifurcation could be displayed in the left and right ventricular outflow tract views. Color and pulse Doppler showed bidirectional or pulmonary-to-aorta shunt flow pattern. All the five APSD cases were confirmed by autopsy.

Conclusions

APSD can be diagnosed by fetal echocardiography. Prenatal diagnosis is important for obstetrical management, early surgical intervention and prognosis.
