A coronary angiogram is a special X-ray test. It’s done to find out if your coronary arteries are blocked or narrowed, where and by how much. An angiogram can help your doctor see if you need treatment such as angioplasty or stent, coronary artery bypass surgery (CABG) or medical therapy.
You will be given a local anesthetic in your groin or your wrist. An incision (cut) is made and a catheter (a fine, flexible, hollow tube) is passed into an artery in your groin or wrist. During the procedure, some dye is injected into the catheter to make your coronary arteries show up on the X-ray.
A routine coronary angiogram takes approximately 30-45 minutes. If the procedure progresses to an angioplasty, then it can last 1-2 hours depending on the type of blockage.
Angiograms are generally safe. However, there are risks with any test. Bleeding, infection and irregular heartbeat can occur. More serious complications, such as heart attack, stroke and death can occur, but they are uncommon.
Like any procedure, an angiogram involves the use of needles and some poking and prodding, but any discomfort is usually minor. … You will not feel pain when the catheter, a slender flexible tube, is inserted into your artery.
Most of the angiograms are done through a pinhole made in the radial artery at wrist joint and the patient can be discharged in the same day. Some of the angiograms are done through the legs and in such situations overnight stay is required for observation. Patient can go for work the very next day of the procedure.
Call your doctor if:
You notice bleeding, new bruising or swelling at the catheter site. You develop increasing pain or discomfort at the catheter site. You have signs of infection, such as redness, drainage or fever. There’s a change in temperature or color of the leg or arm that was used for the procedure.
