Right heart ventriculography
Right heart ventriculography is a study that images the right chambers (atrium and ventricle) of the heart.
How is the Test Performed?
You will get a mild sedative 30 minutes before the procedure. A cardiologist will cleanse the site and numb the area with a local anesthetic. Then a catheter will be inserted into a vein in your neck or groin.
The catheter will be moved forward into the right side of the heart. As the catheter is advanced, the doctor can record pressures from the right atrium and right ventricle.
Contrast material ("dye") is injected into the right side of the heart. It helps the cardiologist determine the size and shape of the heart's chambers and evaluate their function as well as the function of the tricuspid and pulmonary valves.
The procedure will last 1 to several hours.
Preparation for the Test
You will not be allowed to eat or drink for 6 to 8 hours before the test. The procedure takes place in the hospital. Generally, you will be admitted the morning of the procedure. However, you may need to be admitted the night before.
A health care provider will explain the procedure and its risks. You must sign a consent form.
How the Test will Feel
You will be given local anesthesia where the catheter is inserted. The only thing you should feel is pressure at the site. You will not feel the catheter as it is moved through your veins into the right side of the heart. You may feel a flushing sensation as the dye is injected.
Why is the Test Performed?
Right heart angiography is performed to assess the blood flow through the right side of the heart.
Normal Results for Right heart ventriculography
See Swan-Ganz catheterization.
What Abnormal Results Mean
- Abnormal connections between the right and left side of the heart
- Abnormalities of the right atrium, such as atrial myxoma (rarely)
- Abnormalities of the valves on the right side of the heart
- Abnormal pressures or volumes
- Weakened pumping function of the right ventricle (this could be due to many causes)
Right heart ventriculography Risks
- Cardiac arrhythmias
- Cardiac tamponade
- Embolism from blood clots at the tip of the catheter
- Heart attack
- Kidney damage
- Low blood pressure
- Reaction to contrast dye
- Trauma to the vein or artery
This test may be combined with coronary angiography and left heart catheterization.
