Coronary Heart
Disease- Angiography
Angiography is mapping
of any pipe that caries blood or it's components. Like arteriography
is the mapping of pipes that carry the oxygenated [so called pure
blood], Veinography is
the mapping of veins that is the pipes that carry the deoxygenated
blood [so called impure blood], Lymphangiography
is the mapping of the pipes that carry lymph. [Lymph is blood without
the red blood cells and platelets.] Mapping of a particular set of
pipes is known by the name of those pipes. Like the mapping of the
arteries of the heart is called coronary angiography.
In this procedure, a dye is introduced in the concerned blood pipe
and pictures are recorded. This can be done by direct introduction
of dye in the concerned pipe or indirectly introducing the dye in
some other pipe. The pictures can be in the form of sequence of still
films, or cine film showing progress of the dye through the pipes.
Alternately images can be obtained with the help of a computer as
in the case of DSA [Digital Subtraction Angiography], Vascular CT
scan or Vascular MRI scan.
The coronary angiography even though can be done by any of these techniques;
the preferred mode is cine angiography.
