The Inferior and Superior Vena Cava Long-Axis View (The Bicaval View)


This view is obtained by orienting the scan plane along the true sagittal plane of the fetal body immediately to the right of the midline (Fig. 13.1). Alternatively, it is easily obtained with slight translation from a long-axis view of the aortic arch obtained from a parasagittal view of the right chest (Fig. 13.2b). Because this view shows the connection of superior and inferior vena cava with the right atrium, it is also called the bicaval view.

The plane of the bicaval view along a true sagittal plane is shown on the fetal body (a) and on a heart diagram (b). AoV aortic valve, IVC inferior vena cava, MV mitral valve, PV pulmonary valve, SVC superior vena cava, TV tricuspid valve
