The picture on the left (below) shows an image intensifier / camera combination
in the AP view. The corresponding angiogram of a dominant right coronary
artery is shown on the right. The various projections are discussed in
detail in other portions of this lesson.
You may click on the buttons to toggle between
the LAO and RAO projections, or to have a freeze frame of the angiogram
labeled for you.
The diagram on the top left shows a dominant
RCA system, as described on the previous screen, while the diagram on
the top right shows a non-dominant RCA system. Note that the latter supplies
branches to the right ventricle but does not give rise to the PDA, nor
does it continue past the AV groove to supply the PLA branches
The "cine" on the left demonstrates the angiograms
of a non-dominant RCA system in the RAO and LAO projections. Click on
the buttons at the bottom of the angios to toggle between the two views
or to get a labeled freeze frame.
