Key points
- Right heart vetriculography is a study of the right chambers (atrium and ventricle) of the heart.
- An intravenous (IV) line is started in an arm to allow for the administration of medication during the procedure.
- Adults: Food and fluid are restricted for 6 to 8 hours before the test.
- The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust.

Definition
Right heart vetriculography is a study of the right chambers (atrium and ventricle) of the heart. This test is used to obtain measurements of pressure, oxygen, and cardiac output through a catheter (thin flexible tube).
Occasionally, visualization of the right chambers is also necessary. This is obtained by injection of contrast media through the catheter into the right side of the heart with a rapid succession of X-rays taken to capture images of blood flow.
How the test is performed
You are given a mild sedative prior to the test. An intravenous (IV) line is started in an arm to allow for the administration of medication during the procedure.
A cardiologist inserts a catheter through a small incision in a vein in the arm, neck, or groin after cleansing the site and numbing the site with a local anesthetic. The catheter is then carefully threaded into the heart, using a type of X-ray images called fluoroscopy to guide the insertion.
When the catheter is in place, dye is injected to allow the cardiologist to view the blood vessels within the heart.
How to prepare for the test
Adults:
Food and fluid are restricted for 6 to 8 hours before the test. The procedure takes place in the hospital. Generally, you will be admitted as either an outpatient or an inpatient the morning of the procedure. In some cases you may need to be admitted the night before.
A health care provider must explain the procedure and its risks. You must sign a consent form.
A mild sedative is usually given 1/2 hour before the procedure. The procedure may last from one to several hours. You will wear hospital clothing.
Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:
- Infant test or procedure preparation (birth to 1 year)
- Toddler test or procedure preparation (1 to 3 years)
- Preschooler test or procedure preparation (3 to 6 years)
