Cardiac Catheterization


Cardiac Catherization is an invasive procedure that allows cardiologists the ability to take direct angiograms (pictures) of the arteries around the heart (coronary arteries) and measure the pressure within the heart and check the valves and strength of the heart.

It is done in the outpatient setting at the hospital. It is a safe test done everyday. However anytime you enter the body, there is a risk. Just like taking a shower carries risk. While the procedure is 99.9% safe and the risks are small, they are significant and this is why we do not suggest this test unless we feel the benefits significantly outweigh the risks. The major risks include bleeding, infection, impaired kidney function, heart attack, allergic reaction and death.


What To Expect


1. Normally, you will go to the hospital and check in two hours prior to the test. You will have had nothing to eat or drink after midnight unless office has said different. You will take your medication with a small sip of water the morning of the test. You will have discussed with the office about any blood thinners you are taking.


2. You will have been informed about the test, all questions you will have will be answered then you will sign an informed consent.


3. Pre-procedure testing will be done and you will be prepped for the test.


4. An IV will be started and light sedation will be given.


5. Normal procedure will be to use the right groin for access to artery system, although at times an alternative approach may be used.


6. Your groin will be numbed with Novacaine.


7. A needle will be used to gain access to the artery.


8. A sheath will be placed which will act as door for equipment inside and out of your body.


9. X-rays will be used to place tiny tubes in the arteries and dye injected and x-ray pictures of each artery will be recorded. A catheter will be placed across the Aortic valve (doorway into the heart) and pressure will be recorded and dye injected to look at the strength of the heart.


10. After the catheterization all equipment will be removed and either pressure or a device will be placed into the artery to seal the hole created by needle puncture.


11. You will spend several hours at the hospital for observation and then you will be discharged.


12. Total procedure time approximately one hour although this may change depending upon what is encountered during the procedure.


13. This is the best test available to get hard data about the state of your arteries.
