What is heart decatherization?

Heart decatherization is really not a "term." It could, however, be made to mean "the removal of a heart catheter from the coronary arteries."

When someone is suspected of having blocked coronary arteries (maybe after a heart attack), the cardiologist will perform a "heart catheterization." This means that a small, sterile hose is passed through a large artery such as the "Femoral" artery (http://en.wikipedia.org/wiki/Femoral_artery) and threaded up and into the coronary arteries close to the area where the suspected blockage is occuring. The doctor then squirts some fluid through the catheter and views it on an X-ray type machine. The fluid, called "contrast," can be seen by the X-ray for just a moment; Long enough for the doctor to see where the fluid goes. He can then see whether or not the blockage in the artery is a large one or a small one by watching the route of the fluid.

Once he/she determines that there is a blockage and how severe the blockage is, he removes the catheter....this would be decatherization, if you want to call it that.
