What is a Coronary Angiography (Cardiac Catheterisation)?

 

Coronary Angiography, also known as Cardiac Catheterisation, is an invasive imaging test that uses X-rays to visualize the coronary arteries. It involves the insertion of a catheter into the blood vessels to inject a contrast dye, allowing for detailed images of the arteries to detect blockages or abnormalities.

 

What happens during a Coronary Angiography (Cardiac Catheterisation)?

​

During Coronary Angiography:

• You will lie on an examination table.

• A local anaesthetic will be applied to numb the area, typically in the groin or arm, where the catheter will be inserted.

• The catheter is threaded through the blood vessels to the coronary arteries.

• Contrast dye is injected through the catheter, and X-ray images are taken to visualize the coronary arteries.

• The procedure usually lasts about 30 minutes to an hour.

​

Why would I need a Coronary Angiography (Cardiac Catheterisation)?

​

You might need Coronary Angiography if:

• You have symptoms of coronary artery disease, such as chest pain or shortness of breath.

• Non-invasive tests suggest the presence of heart disease.

• Your doctor needs to evaluate the severity and location of blockages in the coronary arteries to guide treatment decisions.

​

Who needs a Coronary Angiography (Cardiac Catheterisation)?

Coronary Angiography may be necessary for:

• Patients with symptoms of coronary artery disease.

• Individuals with inconclusive results from other cardiac tests.

• Those requiring detailed assessment of coronary artery blockages for treatment planning.

​

What are the risks of Coronary Angiography (Cardiac Catheterisation)?

 

Coronary Angiography involves some risks, including:

• Bleeding or bruising at the catheter insertion site.

• Allergic reactions to the contrast dye.

• Damage to the blood vessels or heart.

• Rarely, heart attack or stroke.

​

It's important to note that these risks are rare and the benefits of the test typically outweigh the risks. Additionally, the test is performed under the supervision of trained medical professionals who are equipped to handle any complications that may arise. Your doctor will review your medical history and assess your overall health to determine whether the benefits of the test outweigh the risks for you. If you have concerns about the risks of a stress echocardiogram, discuss them with your doctor before the test.

 

How do I prepare for a Coronary Angiography (Cardiac Catheterisation)?

​

To prepare for Coronary Angiography:

• Follow your doctor’s instructions, which may include fasting for several hours before the test.

• Inform your provider of any allergies, especially to contrast dye or medications, and discuss any medications you are taking.

• Arrange for someone to drive you home after the procedure, as you may be sedated and unable to drive yourself.

• Wear comfortable clothing and remove any jewelry or metal objects.
