What We Do

The Cardiovascular Investigations Unit is where we perform heart catheterizations and angiograms.

Heart catheterization and coronary angiography are x-ray tests to see if there are problems your hearts circulation and it's different chambers or valves. Arteries and chambers do not show up well in a normal x-ray, so we inject a contrast to make them more visible for a short while. The x-ray will allow your doctor to see where your arteries may be blocked and advise you how to treat any heart problem revealed.

At the start of the test, we insert a tube (cathet​er) into one of your arteries or veins in the groin or wrist and guide it to your heart. We then inject contrast through the tube so that we can record proper pictures of your heart's blood vessels.
