Myocardial biopsy, or cardiac biopsy, is procedure that involves using a bioptome (a small catheter with a grasping device on the end) to obtain a small piece of heart muscle tissue to send to a laboratory for analysis.

Why Do I Need a Myocardial Biopsy?

Your doctor uses myocardial biopsy to:

• Evaluate or confirm the presence of rejection after heart transplant.
• Diagnose myocarditis (inflammation of the heart muscle) or the cause of cardiomyopathy (heart muscle disease).

How Should I Prepare for the Biopsy?

• You can wear whatever you like to the hospital, but it is a good idea to leave valuables, such as jewelry, at home. You will wear a hospital gown during the procedure.
• Your doctor or nurse will give you specific instructions about what you can and cannot eat or drink before the procedure.
• Ask your doctor what medications should be taken on the day of your test.
• If you are diabetic, ask your doctor how to adjust your medications the day of your test.
• Tell your doctor and/or nurses if you are allergic to anything.
• Arrange for someone to drive you home after the test.

What Can I Expect During the Procedure?

• After you change into a hospital gown, a nurse will start an intravenous (IV) line in your arm so that medications and fluids can be administered during the procedure.
• You will lie on a special table. If you look above, you will see a large camera and several TV monitors
• You will be awake and conscious during the entire procedure. The doctor will use medication to numb the area of your neck. A plastic introducer sheath (a short, hollow tube through which the catheter is placed) is inserted into a blood vessel. A bioptome will be inserted through the sheath and threaded to your right ventricle. An X-ray camera may be used to position the bioptome properly.
• After the bioptome has obtained samples of your heart muscle, (the sample is about the size of the top of a pin), the catheter is removed and firm pressure is held over the area to stop bleeding.
• The procedure takes about 30 to 60 minutes.
