An angiogram is an invasive test perform with you awake. Most commonly local anaesthetic is injected over the top of the artery in the wrist or sometimes the groin and a small plastic tube is placed in the artery. Through this tube, longer tubes called catheters are navigated to the heart and contrast dye injected allowing us to see the arteries. The angiogram is a diagnostic test which examines the blood supply to the heart. If there are problems with the blood supply this can lead to angioplasty and stents.
