Purpose of the Procedure
A cardiac catheterization is performed to help the doctor assess the function of your heart and its associated blood vessels.
In many cases, you will have undergone one or more other tests such as electrocardiograms, echocardiograms, or stress tests. Other times, a cardiac catheterization is performed after a heart attack or suspected heart attack.
A cardiac catheterization is the best procedure available to detect many heart conditions.
The procedure provides the doctor with the ability to visualize how the heart is working and how the blood flows to the heart. The image to the left is from a cardiac catheterization showing one of the major arteries of the heart.
