Angiography of the coronary arteries

The heart pumps blood to every part of the body. The heart, on the other hand, need blood in order to function. Coronary arteries are three blood channels that supply blood to the heart. Coronary artery disease can be caused by a blockage in these arteries.

Coronary angiography is a medical imaging procedure that involves the use of X-ray equipment to scan the heart. This test produces an image of all three coronary arteries, as well as any constriction within them and their branches.

If you have any of the following symptoms, your doctor may consider a coronary angiography:

  • A heart attack is an example of a sudden emergency
  • Shortness of breath or chest discomfort (also known as angina).
  • Stress test results were positive.

What is a coronary angiography and how does it work?

Coronary arteries are not visible on an X-ray, but they can be seen if a dye that is visible on an X-ray is injected into the bloodstream. A contrast agent or dye is injected into the coronary arteries during coronary angiography to make them visible on an X-ray. An angiography can reveal the extent of your coronary artery disease as well as the best treatment options.

What happens during coronary angiography?

A powerful X-ray machine known as a cardiac catheterization machine is used in a dedicated room known as a cardiac catheterization laboratory to perform the process.

Under local anaesthesia and with the use of x-ray guidance, a catheter is introduced into a blood vessel from the groin or wrist. Radial procedure refers to a technique that is performed through the wrist. The radial approach is now favoured since it is more comfortable for the patient and has fewer difficulties.

After the catheter has reached the target location, contrast material or dye will be inserted into the artery to perform an angiography to determine the location of the blockage. The catheter is then removed, and the groin/wrist puncture is wrapped.

It takes roughly 10-15 minutes to do an angiography. You'll be taken to your room later, where you'll have to rest for a few hours.

After that, you'll be instructed to drink additional water, and the dye will be removed from your body through your urine.

Are there any repercussions?

Angiography is a relatively risk-free procedure. A little bruise on your wrist or groie is possible. Some persons may have an allergic reaction to the colour in rare situations.

What is the post-operative care like, and what are the risks?

  • You have to spend many hours in the hospital ( sometimes a day). Any allergic reactions to the colour will be monitored.
  • If the groin was the site of incision, you should avoid heavy lifting or strenuous exercise for a few days.
  • Your doctor will discuss the possibility of bleeding at the site as well as the precautions that must be taken.

What are the advantages of angiography of the coronary arteries?

A non-invasive diagnostic that produces detailed and accurate images.

Allows for the combination of diagnosis and treatment in a single process, obviating the necessity for multiple procedures.

Angiography serves as a precise and accurate diagnostic technique in the event that a separate procedure is required. The initial stage, for example, is to identify problem areas (using an angiography), followed by angioplasty/stent implantation or bypass surgery to address the problem areas.
