What Is Coronary Angiography?

by Niraj Jayaswal Content Writer


Coronary Angiography is a highly specialised procedure that involves the use of special dye and x-ray pictures to trace the flow of blood through different arteries to detect any kind of blockage. The procedure is used to help patients whose arteries have been blocked due to plaque formation. The procedure is usually performed along with cardiac catheterization. Coronary Angiography is performed at the leading heart hospital in gurugram, India and is a widely trusted procedure recommended by doctors worldwide. It is a highly accurate procedure and proved to be a boon for patients planning to undergo coronary bypass graft surgery by helping to locate the exact position of the blockage. Coronary bypass graft markers in gurgaon use the procedure to mark the area to be operated. This has helped to reduce various complications and made the treatment more effective. In this article, we have tried to elaborate on all the available information about coronary angiography to make it easier for you to understand the importance of the procedure.


What is Coronary Angiography?

Coronary Angiography is a highly advanced imaging test that is used during the assessment and evaluation of a coronary artery (CAD). The procedure involves the use of contrast ink and x-ray technique to keenly examine the arteries of the patient to detect any type of abnormality. The procedure is used during major surgical procedures to guide the doctors and surgeons. The X-rays taken during Angiography are known as angiograms. These help to guide the doctors while treating narrow, blocked, enlarged, or malformed arteries

Why is the procedure performed?

Coronary Angiography is usually performed to detect any kind of blockage in the arteries so as to device out a proper medical protocol to treat the patient. The procedure makes it easier for the doctors to determine the exact location of the blockage and to what extent it has spread. The procedure is used during minimally invasive heart surgeries to guide the doctors. The procedure is usually recommended to patients showing symptoms of CAD, experiencing chronic chest pain, unstable angina, having a congenital heart defect, defects in the blood vessels, chest injury, heart valve problems, etc.

What are the various steps involved?

Before carrying out the procedure, the doctors will briefly study your medical history to make sure that you are not allergic to any of the chemicals used during the procedure. In case you are taking any other medication, your doctor might ask you to discontinue these for some time. The patient is not allowed to eat or drink anything, starting a few hours prior to the procedure.

The procedure is usually carried out under the influence of local anaesthesia however general anaesthesia may be used in case of kids especially infants.

During the procedure, the patient is kept on an electrocardiogram machine to monitor the heart rhythm and its electrical activity

It is a catheter-based, minimally invasive procedure. The catheter is inserted inside the patient's body via the groin or a small incision on the arm or the side of the chest. The concerned area is numbed by the use of local anaesthesia. The catheter is slowly moved towards the heart with the help of the x-ray guidance. A small amount of contrast dye is then injected through the catheter. This dye helps to make the images generated by the x-ray machine even more clearer thereby making it easier for the doctors to treat the patient.

What happens after the procedure?

After the procedure is performed, the patient is kept under keen observation until his condition is stable. You will be asked to lay down on your back for several hours to avoid bleeding. Pressure may also be applied at the site of the incision to prevent bleeding. Patients are usually discharged within a day or two. It is recommended to take plenty of fluids to flush out the dye from your body as soon as possible. Normal activities can be restored within a week. Make sure that the site of incision is clean and covered at all times to avoid unnecessary infection.

Immediately inform your doctor if you experience any of these:

Bleeding and bruising at the site of incision

Swelling near the wound

Persistent pain or discomfort at the catheter site

Change in body temperature


Redness at the site of the incision.

What are the benefits of the procedure?

Coronary angiography is a minimally invasive procedure which means that there is minimal scarring, decreased complications, shorter recovery period and better results.

It can help the doctors to determine the number of arteries that have been affected by atherosclerosis.

It can help to determine the exact location of the blockage.

It can help to determine the amount of blood flow that has been restricted.

It's can help to check the results of previous coronary bypass surgery.

What are the various risks involved?

Although coronary angiography has a lot of benefits it certain risks associated with it as well. These include:

Increased risk of heart attack and stroke

Injury to the concerned artery


Allergic reactions to the contrast dye used during the procedure

Chronic damage to kidneys

Excessive bleeding.

Wound infection


Hence coronary angiography is a highly trusted procedure that has gained a lot of popularity among the coronary bypass graft markers in gurgaon. The procedure has helped to reduce various risks associated with the treatment of diseases related to the coronary artery by giving a detailed view of the same. This has not only added to the precision and accuracy but also helped to make the treatment even more effective. The information gained by the tests can help your doctor to determine a specialised treatment program. Sometimes procedures like angioplasty or stenting are done along with the angiogram to avoid the need for another procedure. However, you cannot negate the risks associated with angiography and it is important to keep these in mind before proceeding with the test. The dye used during the procedure can have a drastic impact on your kidneys and also trigger other allergic reactions. Hence it is important to discuss the whole procedure with your doctor beforehand.
