Interventional cardiology
Coronary Angiography
A catheter-based examination that provides detailed images of the coronary arteries and identifies narrowing or blockages.
Overview
Coronary angiography uses contrast material and X-ray imaging to show the vessels supplying the heart. It helps define whether medication, stenting or surgery should be considered.
Who may be considered?
It may be recommended for chest pain, suspected coronary artery disease, abnormal stress-test findings, acute coronary syndromes or before selected heart operations.
How is the procedure performed?
Under local anaesthesia, a thin catheter is usually advanced through the radial artery at the wrist. Contrast images are recorded from several angles; treatment may follow in the same session when appropriate.
Recovery and follow-up
After radial access, mobilisation and discharge are often possible within a few hours. Hydration, access-site care and the prescribed medication plan are important.
Risks and safety
Bleeding or bruising at the access site, contrast reactions, kidney injury, rhythm disturbances and vascular complications are possible; serious complications are uncommon in appropriately selected patients.
