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
