Right heart ventriculography

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.

Alternative Names:

Angiography - right heart

How the test is performed:

A cardiologist inserts a catheter into a vein in the neck or groin after cleansing the site and numbing the area with a local anesthetic.

When the catheter is in place, dye is injected to allow the cardiologist to view the size and shape of the cardiac chambers.

How to prepare for the test:

Food and fluid are restricted for 6 - 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.

How the test will feel:

A vein is accessed in the neck or groin for threading the catheter into your heart. You are given a local anesthesia for the insertion of the catheter, and the only sensation should be one of pressure at the site.

Why the test is performed:

Right-heart angiography is performed to detect abnormalities in blood flow through the right side of the heart.
