Left heart ventricular angiography

Left heart ventricular angiography

Definition

Left heart ventricular angiography is a procedure to look at the left side of the heart and, sometimes, the coronary arteries.

Alternative Names

Angiography - left heart; Left cardiac catheterization; Left ventriculography

Why the Test is Performed

This test is done to detect:

  • Blood flow problems on the left side of the heart
  • Abnormalities of the left heart valves
  • Heart-related blockages

How the Test is Performed

Before the test, you will be given medicine to help you relax, but you will be awake and able to follow instructions during the test.

An intravenous line is placed in your arm. The health care provider cleans and numbs an area on your arm or groin. A cardiologist makes a small cut in the area, and inserts a thin flexible tube (catheter) into an artery. Using x-rays as a guide, the doctor carefully moves the thin tube into your heart. When in place, dye is injected through the tube. The dye flows through the blood vessels, making them easier to see. X-rays are taken as the dye moves through the blood vessels.

The procedure may last from 1 to several hours.

How to Prepare for the Test

You will be told not to eat or drink for 6 - 8 hours before the test. The procedure takes place in the hospital. Some people may need to stay in the hospital the night before the test.

A health care provider will explain the procedure and its risks. You must sign a consent form for the procedure.

How the Test Will Feel

You may feel pressure when the catheter is inserted. Occasionally, a flushing sensation occurs when the dye is injected.

Risks

Risks associated with this procedure include:

Considerations

Right heart catheterization may be combined with this procedure.

Normal Results

A normal result shows normal blood flow through the left side of the heart, plus normal blood volumes and pressures.

What Abnormal Results Mean

An abnormal result may suggest a problem with the left side of the heart or the heart valves. Coronary angiography may be needed when blockage of the coronary arteries is suspected.
