Although many angioplasties are performed by puncturing the vessel through the skin, others are done by surgically exposing the site of entry. Direct view of the vessel's puncture site aids in monitoring damage to the vessel
arterial puncture is typically made in the femoral artery, and the cardiologist uses a guide wire and catheter to perform a contrast injection and x-ray series on the coronary arteries. The catheter may also be placed in the left ventricle
Coronary angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through your heart.
Alternative NamesCardiac angiography; Angiography - heart; Angiogram - coronary
How the test is performedCoronary angiography is usually done along with cardiac catheterization.
Before the test starts, you will be given a mild sedative to help you relax.
An area of your body, usually the arm or groin, is cleaned and numbed with a local numbing medicine (anesthetic). The cardiologist passes a thin hollow tube, called a catheter, through an artery and carefully moves it up into the heart. X-ray images help the doctor position the catheter.
Once the catheter is in place, dye (contrast material) is injected into the catheter. X-ray images are taken to see how the dye moves through the artery. The dye helps highlight any blockages in blood flow.
The procedure may last 30 to 60 minutes.
How to prepare for the testYou should not eat or drink anything for 8 hours before the test starts. You may need to stay in the hospital the night before the test. Otherwise, you will check in to the hospital the morning of the test.
You will wear a hospital gown. You must sign a consent form before the test. Your health care provider will explain the procedure and its risks.
Tell your doctor if you are allergic to seafood, if you have had a bad reaction to contrast material in the past, if you are taking Viagra, or if you might be pregnant.
How the test will feelYou are awake during the test. You may feel some pressure at the site where the catheter is inserted.
Occasionally, a flushing sensation occurs after the dye is injected.
After the test, the catheter is removed. You might feel a firm pressure at the insertion site, used to prevent bleeding. If the catheter is placed in your groin, you will usually be asked to lie flat on your back for a few hours after the test to avoid bleeding. This may cause some mild back discomfort.
Why the test is performedCoronary angiography is done to find a blockage in the coronary arteries, which can lead to heart attack. It may be done if you have unstable angina, atypical chest pain, aortic stenosis, or unexplained heart failure.
Normal ValuesThere is a normal supply of blood to the heart and no blockages.
What abnormal results meanAn abnormal result may mean you have a blocked artery. The test can show how many coronary arteries are blocked, where they are blocked, and the severity of the blockages.
What the risks areCardiac catheterization carries a slightly increased risk when compared with other heart tests. However, the test is very safe when performed by an experienced team.
Generally the risk of serious complications ranges from 1 in 1,000 to 1 in 500. Risks of the procedure include the following:
Considerations associated with any type of catheterization include the following:
If a blockage is found, your health care provider may perform a percutaneous coronary intervention (PCI) to open the blockage. This can be done during the same procedure.

Sodium fluorescein dye is then injected with a syringe into a vein in the patient's arm. The dye travels through the patient's body and into the blood vessels of the eye
Radioactive material is injected into the bloodstream. A device that uses gamma rays to produce an image of the radioactive material (gamma camera) records pictures of the heart
Diagnostic tests include: resting, exercise, or ambulatory electrocardiograms; scintigraphic studies; echocardiography; coronary angiography; and rarely positron emission tomography.
You are likely referring to an angiogram. Angiogram means the 'recording' of any blood vessel, not necessarily coronary. I would say your best answer is 'coronary angiography' this is performed via a procedure called 'cardiac catheterization'

The coronary sinus runs in the posterior coronary sulcus. In the anterior coronary sulci the stems of the coronary artery run. The circumflex branch of the left and the extension of the right coronary artery that becomes the posterior descending artery run around the coronary sulcus from front to back
The coronary arteries supply blood to the myocardium (heart muscle).
Coronary angiography is administered by a cardiologist with training in radiology or, occasionally, by a radiologist

Coronary arteries can be visualized most accurately at autopsy. Pre-mortem imaging can be performed by way of a cardiac catheterization. Computed tomography-angiography of the coronary vessels shows some promise, but is not as accurate as plain angiography. Magnetic resonance angiography also can show the cardiac vasculature, but again, is somewhat limited in its usefulness due to the time it takes to obtain the pictures and other technical factors, such as heart rate and rhythm.
the guide wire and catheter are inserted into a vein instead of an artery, and are guided up through the chambers of the heart and into the pulmonary artery

Because life-threatening internal bleeding is a possible complication of an arterial puncture, an overnight stay in the hospital is sometimes recommended following an angiographic procedure, particularly with cerebral and coronary angiography
Angiography is an imaging test that utilizes X-beams to see your body's veins. The X-beams gave by an angiography are called angiograms. This test is utilized to contemplate limited, blocked, extended, or twisted corridors or veins in numerous pieces of your body, including your mind, heart, midsection, and legs.A coronary angiogram is a X-beam of the supply routes in the heart. This shows the degree and seriousness of any coronary illness, and can assist you with figuring out how well your heart is functioning.To create the X-ray images, your doctor will inject a liquid dye through a thin, flexible tube, called a catheter. The doctor threads the catheter into the desired artery from an access point. The access point is usually in your arm but it can also be in your groin. The dye makes the blood flowing inside the blood vessels visible on an X-ray and shows any narrowed or blocked area in the blood vessel. The dye is later eliminated from your body through your kidneys and your urine.
