CT Coronary Angiogram VS Conventional Coronary Angiogram
WHAT SHOULD YOU KNOW

A CT Coronary Angiogram (CTCA) and a Conventional Coronary Angiogram (CCA) (also called Invasive Coronary Angiography) are both used to assess coronary artery disease (CAD), but they differ in technique, invasiveness, and clinical application.

1. CT Coronary Angiogram (CTCA)

1. Non-invasive: Uses a high-resolution CT scan with contrast to visualize coronary arteries.
2. Quick procedure: Takes about 10-15 minutes.
3. No hospital stay required: Done as an outpatient test.
4. Best for low-to-moderate risk patients: Used for screening and evaluating suspected CAD
5. Detects plaques and stenosis: Can assess both calcified and non-calcified plaques.
6. Exposure to radiation: Uses X-rays and contrast dye, but at lower doses than CCA.
7. Not suitable for high-risk patients: If severe blockage is found, a conventional angiogram may still be needed.

2. Conventional Coronary Angiogram (CCA)

1. Gold standard for diagnosing CAD: Provides detailed, real-time visualization of coronary arteries.
2. Can perform treatment (PCI/Stenting): If a blockage is found, doctors can immediately place a stent.
3. More precise for severe cases: Used for patients with high-risk CAD, previous heart attacks, or angina.
4. Invasive procedure: A catheter is inserted into the artery (usually via the wrist or groin).
5. Risk of complications: Small risk of bleeding, infection, stroke, or heart attack.
6. Requires hospital stay: Usually done in a catheterization lab with sedation.

When to Choose Which?

• CTCA → Best for early detection, screening, and low-risk patients.
• CCA → Best for high-risk patients, those needing stenting, or when severe blockages are suspected.
