Figure 1 Echocardiography of APVS at 14 weeks of gestation
A. Longitudinal view of DA showed the retrograde blood flow from DA to
PA; B. 3VT view showed the retrograde blood flow in PA; C. Oblique PA
branches view showed that RPA and LPA were not dilated and the blood
flow was unobstructed; D. 4 chamber view showed poorly aligned VSD
VSD: ventricular septal defect; AAO: aortic arch; DAO: descending aorta;
PA: pulmonary artery; LPA: left pulmonary artery; RPA: right pulmonary
artery; RV: right ventricle; LV: left ventricle; RA: right atrium; LA:
left atrium; IVC: inferior vena cava; VSD: ventricular septal defect
White arrow indicates right to left shunt through VSD
