Cardiac catheterization

Definition

Cardiac catheterization involves passing a thin flexible tube (catheter) into the right or left side of the heart. The catheter is most often inserted from the groin or the arm.

Alternative Names

Catheterization - cardiac; Heart catheterization

How the Test is Performed

You will get medicine before the test to help you relax.

The health care provider will clean a site on your arm, neck, or groin and insert a line into one of your veins. This is called an intravenous (IV) line.

A larger thin plastic tube called a sheath is placed into a vein or artery in your leg or arm. Then longer plastic tubes called catheters are carefully moved up into the heart using live x-rays as a guide. Then the doctor can:

If you have a blockage, you may have angioplasty and a stent placed during the procedure.

The test may last 30 - 60 minutes. If you also need special procedures, the test may take longer. If the catheter is placed in your groin, you will often be asked to lie flat on your back for a few to several hours after the test to avoid bleeding.

You will be told how to take care of yourself when you go home after the procedure is done.

How to Prepare for the Test

You should not eat or drink for 6 - 8 hours before the test. The test takes place in a hospital and you will be asked to wear a hospital gown. Sometimes, you will need to spend the night before the test in the hospital. Otherwise, you will come to the hospital the morning of the procedure.

Your health care provider will explain the procedure and its risks. A witnessed, signed consent form for the procedure is required.

Tell your doctor if you:

How the Test will Feel

The study is done by cardiologists and a trained health care team.

You will be awake and able to follow instructions during the test.

You may feel some discomfort or pressure where the catheter is placed. You may have some discomfort from lying still during the test or from lying flat on your back after the procedure.

Why the Test is Performed

This procedure is most often done to get information about the heart or its blood vessels. It may also be done to treat some types of heart conditions, or to find out if you need heart surgery.

Your doctor may perform cardiac catheterization to diagnose or evaluate:

The following procedures may also be done using cardiac catheterization:

Risks

Cardiac catheterization carries a slightly higher risk than other heart tests. However, it is very safe when done by an experienced team.

The risks include:

Possible complications of any type of catheterization include the following:
