What Are The Risks Of Having An Angiogram – Coronary angiography, also called coronary angiography or cardiac catheterization, is an X-ray procedure in which a doctor injects a radioactive dye into the coronary arteries to see the heart’s blood vessels. The dye shows up on an X-ray screen. Coronary angiography is usually done to see if blood flow to and from the heart is blocked or restricted. If your doctor suspects you have heart disease, he may order a coronary angiogram.
Coronary angiography allows your doctor to look inside your coronary arteries to see where and how severe the narrowed areas are.
What Are The Risks Of Having An Angiogram
During a coronary angiogram, a type of X-ray-visible dye is injected into the blood vessels of the heart. An x-ray machine quickly takes a series of pictures (angiograms) and looks at your blood vessels. If necessary, the doctor may open blocked heart arteries (angioplasty) during a coronary angiogram.

If you have symptoms that indicate your heart isn’t getting enough blood, such as chest pain or a heart attack, your doctor may recommend a coronary angiogram.
If you have a congenital heart defect, have had a major chest injury, or have problems with blood vessels in other parts of your body, you may have a coronary angiogram.
Because of the low risk of complications, angiograms are usually not performed until noninvasive heart tests such as an electrocardiogram (ECG), echocardiogram, or stress test are performed.
A coronary CT angiogram shows blood flow through the coronary arteries. This test is similar to a traditional coronary angiogram. But in this test, the dye is injected into a small vein in the arm instead of an artery in the groin. This makes the test less invasive than a traditional angiogram. You’ll then lie on a bed where a CT scanner passes through a doughnut-shaped hole to create an image of your heart.
What Is Angioplasty?
In some cases, coronary angiograms are performed urgently. However, they are usually planned in advance and allow time for preparation.
They will talk to you, examine you, and may do additional tests, such as blood tests, chest X-rays, and electrocardiograms or EKGs.
Angiograms are performed in the hospital’s catheterization (catheterization) laboratory. Your healthcare team will give you specific instructions and talk about the medicines you take. General guidelines include:
Before starting your angiogram procedure, your healthcare team will review your medical history, including allergies and medications. Your medical team may perform a physical examination and check your vital signs: blood pressure and pulse.

You will also empty your bladder and put on a hospital gown. You may need to remove contacts, glasses, jewelry, and hairpins.
You will be taken to a special cardiac catheterization laboratory or operating room and asked to lie on a narrow X-ray table. Your medical team will insert an intravenous (IV) line and may give you sedatives, as well as other medications and fluids. You will be very sleepy and may fall asleep during the procedure, but you may still wake up to follow instructions.
Because the table may tilt during the procedure, safety straps may be worn around the chest and legs. X-ray cameras can be moved around your head and chest to take pictures from many angles.
During the procedure, electrodes are placed on the chest to monitor the heart. A blood pressure cuff monitors your blood pressure, and another device, a pulse oximeter, measures the amount of oxygen in your blood.

A small amount of hair may be shaved into which a flexible tube (catheter) can be inserted from the scalp or arm. The area is washed and disinfected.
Before your medical team makes a small incision, they will inject a local anesthetic into your groin. A short plastic tube (cap) is then inserted into the artery, and a catheter, a long, thin tube, is inserted through a sheath into a blood vessel and carefully inserted into the heart or coronary arteries. Sometimes the hand is used instead of the hip.
Arteries have no nerves, so you shouldn’t feel it. Threading the catheter should not cause pain and you should not feel it move in your body. Tell your healthcare team if you experience any discomfort.
After the catheter is in place, dye (contrast material) is injected into the catheter. When this happens, you may experience some redness or warmth. But again, tell your healthcare team if you feel pain or discomfort.
Diagnostic Cardiac Catheterization And Coronary Angiography
The dye can be easily seen on X-rays. As it moves through your blood vessels, your doctor can track its flow and identify any blockages or restricted areas. Depending on what your doctor finds during your angiogram, you may have additional catheter procedures, such as balloon angioplasty or stenting to open a narrowed artery.
Obtaining an angiogram takes about an hour, but it may take longer, especially if it is combined with other cardiac catheterization procedures. Preparation and post-procedure care can add more time.
After the coronary angiography is completed, the catheter is withdrawn into the arm or groin, and the incision is closed with manual pressure, a clamp, or a small plug.
You will be taken to the recovery area for observation and monitoring until you are ready to return to the room.
Cerebral Angiogram Risks And Benefits
If the catheter is inserted in the groin, you will have to lie down for several hours to stop the bleeding. During this time, pressure may be applied to the incision to prevent bleeding and promote healing.
You may go home the same day or you may have to stay overnight in the hospital. Drink plenty of fluids to help flush the dye out of your body. If you’re feeling energized, grab something to eat.
Ask your healthcare team when you should resume taking medications, bathing or showering, working, and other normal activities. Avoid strenuous activity and heavy lifting for a few days.
Your piercing will remain tender for a while. It may have some bruising and small bumps.
Important Angioplasty Questions And Answers
As with most heart and blood vessel procedures, there are some risks, such as radiation from the X-rays used in coronary artery angiograms. However, serious complications are rare. Possible risks and complications of coronary artery angiography include:
If the catheter site is actively bleeding and does not stop after applying pressure, call your local emergency number. If the catheter site suddenly becomes swollen, call your local emergency number.
Knowing this information can help your doctor determine the best treatment for you and how dangerous your heart problem is to your health. Based on your results, your doctor may decide that you would benefit from, for example, coronary angioplasty or stenting to clear blocked arteries. Angioplasty or stent placement can also be performed during a coronary angiogram to avoid the need for another procedure. A coronary angiogram is a diagnostic procedure in which the heart’s blood vessels are visualized using X-rays. Under local anesthesia, a small catheter is inserted into the heart from the wrist or groin and a special “dye” (contrast agent) is used. should be injected into the blood vessels that supply the heart muscle. Digital images and videos are recorded using special X-ray cameras.
Also known as cardiac catheterization or coronary angiography, this procedure was first performed by Dr. Mason Sones in 1958 and is the gold standard for diagnosing coronary artery disease.
Ct Coronary Angiography
These pictures and videos allow your doctor to visualize what’s going on inside your blood vessels. Depending on what is seen, they may perform procedures to open partially or completely blocked arteries. It can also determine how well the valves between the heart chambers are working and how well the heart muscle is pumping.
The heart is a muscular organ kept alive by millions of blood vessels. The three most important major blood vessels are the left anterior descending artery (LAD), the left circumflex artery (LCx), and the right coronary artery (RCA). If the heart does not get enough oxygen, it can cause chest pain or a heart attack.
Atherosclerosis is a process in which fatty deposits deprive the heart muscle of the oxygen and nutrients it needs to function properly, narrowing the coronary arteries. Over time, this can weaken or damage the heart. If a plaque ruptures or ruptures, the body tries to repair it by forming a blood clot around it. A new blood clot can block blood in an artery and stop blood flow to the heart. This is a common cause of “heart attack”.
Coronary angiography can help determine what’s wrong with your heart and, in many cases, help your cardiologist diagnose the problem, relieve your symptoms, increase your longevity, and reduce your risk of sudden death.
