CT Angiogram vs Conventional Coronary Angiography

CT Angiogram vs Catheter Angiogram

Great debates with the use of angiography and the types available. Many centres do no have the luxury of having a CT angiogram. Both procedures involve radiation and are used for patients with or potential heart problems.
The main advantage of a CT Angiogram:
1. Non-invasive
2. Fast
3. Painless
4. No hospitalization (non-invasive so no overnight monitoring required)

The big questions is: Is the angiogram for diagnostic or interventional purposes? The benefit of doing a conventional Angiogram, catheter angiogram is that the patient is already prepared to a revascularization procedure, stent.
CT angiograms can differentiate between calcified and non-calcified in the coronary artery. <br>

Contraindications:
1. Hypersensitivity to the injected contrast agent.

2. Kidney insufficiency.

3. Congestive Heart Failure

4. Atrial Fibrillation

5. Unable to hold breath for 5 seconds

CT Angiograms have their place unfortunately in Calgary, we only have private ones and use catheter Angiograms for diagnostic and interventional procedures.

There is a place for this as I feel it could possibly replace the need for thallium or MIBI scans in the future for the detection of CAD.
After all with the use of stents to open up arterial walls, cardiologists are more and more starting medical therapy and lifestyle intervention to halt, prevent or reverse the disease process vs stents. So best practice is to treat patient symptoms and incorporate a heart healthy lifestyle to reverse heart disease.

To your success,
