Abstract:
We reported a case of fetus with right atrial isomerism diagnosed by ultrasound prenatally. Right atrial isomerism was suspected based on several kinds of abnormalities detected at 24 gestational weeks by ultrasound imaging, such as levocardia complicated by complex cardiovascular malformations (double outlet of right ventricle, atrioventricular septal defect, pulmonary artery dysplasia, bilateral superior vena cava and infracardiac total anomalous pulmonary venous drainage), abnormal right-sided stomach bubble, midline liver, suspicious absence of the spleen, juxtaposition of the abdominal aorta and the inferior vena cava to the left side, and mirror-image right bronchia. Autopsy confirmed all of the prenatal diagnosis with an additional finding of splenic dysplasia. Right atrial isomerism should be considered when ultrasound findings indicate complex cardiovascular malformations. Given the high mortality rate of right atrium isomerism, prenatal diagnosis is of great importance.
