This is a test for patients with suspected serious heart artery blockages (diagnosed from stress test or CT angiogram), recent or previous heart attacks.

Dr Wong practices radial angioplasty in >90% of his cases where the access is the radial artery at the wrist rather than the groin. Radial approach has lower bleeding and local complications.

What Is Angiography?

A Catheter Angiography is an invasive diagnostic procedure that uses a dye (contrast) and a special x-ray (fluoroscopy) to take pictures of the blood flow in your heart’s arteries. These pictures are called angiograms.


Catheter Angiography allows your Cardiologist to see precisely if there is any narrowing in your heart arteries, where the site is exactly and how severe the problem is. It can also assess the function of your heart. This helps your Cardiologist or Cardiothoracic Surgeon choose the most appropriate treatment option for you.

Catheter Angiography is performed if you have, or are suspected to have coronary artery disease. Your doctor may recommend that you have the test if:


  • you have chest pain that your doctor suspects is caused by narrowed coronary arteries, but he or she wants to be sure your doctor wants to assess the degree of narrowing in your coronary arteries to see if you could benefit from a procedure such as angioplasty or bypass surgery, to relieve your symptoms and reduce your risk of further heart problems.

  • you have had a heart attack—if you had treatment to dissolve the clot blocking your coronary artery, or you have continuing chest pain, or the results of an exercise test indicate the need for further

Please ensure that your artery blockages are >70% before considering angioplasty or bypass surgery. Speak to our cardiologist and he will teach you to estimate the blockages yourself...Read More
