When you have completed review of this screen, please click the "Next page" blue arrow for the second portion of this section.

A shallow LAO view with a 25 to 45 degrees cranial angulation is a superior view for:

- displaying the origin of the RCA and its shaft.
- It reduces foreshortening of the right Posterior descending coronary artery and "un-stacks" it from the right Postero-lateral branch.
- It may also clearly demonstrate the proximal portion of the acute marginal branch.
-
A deep held inspiration is needed to clear the diaphragm and improve image quality.
-
Indeed, this view usually offers so much more information than the "straight" LAO view that it has become the LAO view of choice for some cardiac cath labs.

  In the Left Anterior  Oblique or LAO view, the camera is rotated along a vertical axis towards the patient's left.  Please note that the ventricular septum lies in a plane between the right shoulder and the left nipple. In the LAO/Cranial  view, the camera "looks" at the edge of the septum from above. The outline of the atrio-ventricular plane is roughly at right angles to the ventricular septum.
