Renal or kidney arteriograms view the blood supply of the kidney. Leg arteriograms check blood flow to the leg and groin areas. Aortic arteriograms outline the major blood vessel of the chest and the abdomen. Angiography, angiogram, or arteriograms are terms that describe a procedure used to identify narrowing or blockages in the arteries in the body.
The procedure is the same regardless of what area of the body is being viewed. A small tube called a catheter is placed in a large blood vessel at the top of the leg or in the groin region. The doctor carefully guides the catheter to the problem area heart, leg, neck, kidney, or aorta using moving x-ray pictures. By watching the flow of dye through the vessels with x-ray equipment, the doctor identifies obstructions and narrowing. If you live a considerable distance from the Heart Institute, check with the doctor to see if you should stay close to the hospital the night of discharge.
Arrangements for accommodations should be made in advance. Skip to main content View sitemap. Angiogram Cardiac Catheterization Also called: Cardiac cath, coronary angiogram, dye test. Many of our patients also find it helpful to bring: A family member or friend to take notes or ask questions A list of your own questions to ensure that you have all the information Before you have a coronary angiogram, expect to have: An assessment by a nurse that includes measuring your blood pressure and other vital signs A session to teach you about the procedure Review and signing of the consent form Blood tests and an electrocardiogram Specific instructions about your medications Cleaning and preparation of a small area of both groins or your wrist Immediately before the procedure, you will be taken to the cardiac catheterization lab.
You will be given medication to help you relax, but you will be awake during the procedure so that you can follow instructions from the doctor and nurses. The doctor will administer freezing to your groin or your wrist. A small catheter will be threaded through an artery in your wrist or groin and guided up to the heart.
X-ray pictures will be taken and a special dye will be injected through the catheter to highlight your coronary arteries and identify if there are any narrowed sections or blockages. Most patients experience a sensation of body warmth as the dye is injected or the urge to empty their bladder. Consider printing out or writing down these questions and taking them with you to your appointment. Find an Interventional Cardiologist. Heart Condition Centers. An angiogram will show: That blood flow to your heart is not being restricted by blockages -- a finding that lets you and your doctor know your symptoms are not related to your heart; or That the arteries to your heart are narrowed or blocked, exactly where the blockages are located and their size -- information that will enable the cardiologist to develop a treatment plan.
How Does an Angiogram Work? How Is an Angiogram Performed? Before the Angiogram Your cardiologist or nurse practitioner will offer instructions on how to prepare for the angiogram. If you take medications, such as blood-thinners, consult with your cardiologist about whether you should stop taking them before the angiogram. Aspirin should be continued. You will be asked not to eat or drink anything for several hours before the procedure. Your blood count, kidney function and blood clotting tests may be performed beforehand.
You will receive medications to help you relax before the procedure begins. During the Angiogram This content requires Flash Player. Heart News 1 2 3 4 5 Next ». What Causes Atrial Fibrillation?

It is sometimes called conventional angiography to distinguish it from computed tomography CT angiography and magnetic These tests are usually done when noninvasive tests Introduction to Diagnosis of Heart and Blood Vessel Disorders Sometimes, medical history and physical examination alone suggest to a doctor that the person has a heart or blood vessel disorder.
However, special diagnostic procedures are often needed to One advantage to these tests is that during the test, doctors can also treat various diseases, including coronary artery disease Overview of Coronary Artery Disease CAD Coronary artery disease is a condition in which the blood supply to the heart muscle is partially or completely blocked. The heart muscle needs a constant supply of oxygen-rich blood. The coronary More than a million cardiac catheterizations and angiographic procedures are done every year in the United States.
They are relatively safe, and complications are rare. With cardiac catheterization and angiography, the chance of a serious complication—such as stroke Overview of Stroke A stroke occurs when an artery to the brain becomes blocked or ruptures, resulting in death of an area of brain tissue due to loss of its blood supply cerebral infarction and symptoms that This blockage causes unstable angina or heart attack myocardial infarction , depending on the location and amount Fewer than 1 in 10, people undergoing these procedures die, and most of those who die already have a severe heart disorder or other disorder.
The risk of complications and death is increased for older people. Cardiac catheterization is used extensively for the diagnosis and treatment of various heart disorders. Cardiac catheterization can be used to measure how much blood the heart pumps out per minute cardiac output , to detect birth defects of the heart, and to detect and biopsy tumors affecting the heart Overview of Heart Tumors A tumor is any type of abnormal growth, whether cancerous malignant or noncancerous benign.
Tumors in the heart may be Primary noncancerous or cancerous Metastatic always cancerous Primary This procedure is the only way to directly measure the pressure of blood in each chamber of the heart and in the major blood vessels going from the heart to the lungs. A local anesthetic is given to numb the insertion site. The procedure is done in the hospital and takes 40 to 60 minutes.
Various small instruments can be advanced through the tube to the tip of the catheter. They include instruments to measure the pressure of blood in each heart chamber and in blood vessels connected to the heart, to view or take ultrasound images of the interior of blood vessels, to take blood samples from different parts of the heart, or to remove a tissue sample from inside the heart for examination under a microscope biopsy.
Common procedures done through the catheter include the following:. Coronary angiography: A catheter is used to inject a radiopaque contrast agent Labeling with a radionuclide In radionuclide scanning, radionuclides are used to produce images.
A radionuclide is a radioactive form of an element, which means it is an unstable atom that becomes more stable by releasing Ventriculography: A catheter is used to inject a radiopaque contrast agent into one or more heart chambers so that they can be seen on x-rays. Percutaneous coronary intervention PCI : A catheter with a balloon attached to the tip is threaded into a narrowed coronary artery and the balloon is inflated to open the narrowed area.
Doctors typically use the catheter to insert a wire mesh tube a stent into the artery to hold it open. Valve replacement: A catheter is used to replace a valve in the heart without removing the old valve or doing surgery.
Ventriculography is a type of angiography in which x-rays are taken as a radiopaque contrast agent is injected into the left or right ventricle of the heart through a catheter.
It is done during cardiac catheterization. With this procedure, doctors can see the motion of the left or right ventricle and can thus evaluate the pumping ability of the heart.
