Left heart catheterization
Catheterization - left heart
Left heart catheterization is the passage of a thin flexible tube (catheter) into the left side of the heart. It is done to diagnose or treat certain heart problems.
How the Test is Performed
You may be given a mild medicine (sedative) before the procedure starts. The medicine is to help you relax. The health care provider will place an IV into your arm to give medicines. You will lie on a padded table. Your doctor may make a small surgical cut on your body. A flexible tube (catheter) is inserted through the cut into an artery. It will be placed in your wrist, arm or your upper leg (groin). You will most likely be awake during the procedure.
Live x-ray pictures are used to help guide the catheters up into your heart and arteries. Dye (sometimes called "contrast") will be injected into your body. This dye will highlight blood flow through the arteries. This helps show blockages in the blood vessels that lead to your heart.
The catheter is then moved through the aortic valve into the left side of your heart. The pressure is measured in the heart in this position. Other procedures, can also be done at this time, such as:
-
Ventriculography
to check the heart's pumping function

The procedure may last from less than 1 hour to several hours.
How to Prepare for the Test
In most cases, you should not eat or drink for 8 hours before the test. (Your provider may give you different directions.)
The procedure will take place in the hospital. You may be admitted the night before the test, but it is common to come to the hospital the morning of the procedure.
Your provider will explain the procedure and its risks. You must sign a consent form.
How the Test will Feel
The sedative will help you relax before the procedure. However, you will be awake and able to follow instructions during the test.
You will be given local numbing medicine (anesthesia) before the catheter is inserted. You will feel some pressure as the catheter is inserted. However, you should not feel any pain. You may have some discomfort from lying still for a long period of time.
Why the Test is Performed
The procedure is done to look for:
- Cardiac valve disease
- Cardiac tumors
-
Heart defects (such as
ventricular septal defects
)
Ventricular septal defects
Ventricular septal defect is a hole in the wall that separates the right and left ventricles of the heart. Ventricular septal defect is one of the m...
- Problems with heart function
The procedure may also be done to evaluate and possibly repair certain types of heart defects, or to open a narrowed heart valve.
When this procedure is done with coronary angiography , it can open blocked arteries or bypass grafts.

The procedure can also be used to:
- Collect blood samples from the heart
- Determine pressure and blood flow in the heart's chambers
- Examine the arteries of the heart (coronary angiography)
- Take x-ray pictures of the left ventricle (main pumping chamber) of the heart (ventriculography)
Normal Results
A normal result means the heart is normal in:
- Size
- Motion
- Thickness
- Pressure
The normal result also means arteries are normal.
What Abnormal Results Mean
Abnormal results may be a sign of cardiac disease or heart defects, including:
-
Aortic insufficiency
