Figure 4: (a) Bicaval view. (b) Same as Figure (a), but with labels. The two angles: angle number 1 that is between the axis of inferior vena cava and the line passing through the tricuspid valve orifice and the angle number 2 that is between the axis of inferior vena cava and the line passing through the tricuspid valve orifice. The first angle is 60° and the second is 50°. Flow enters into the right atrium from the two sides with almost the same angle toward the tricuspid valve orifice. This can lead to augmentation of flow and increased A velocity
