A coronary arteriogram, also known as arteriography, is a diagnostic procedure to examine the blood vessels and chambers within the heart using X-ray imaging. This procedure is performed by inserting a catheter into a blood vessel in the upper thigh or arm area and threaded to the heart where a contrast dye is delivered. The dye is visible on the X-ray images and can help identify any abnormalities within the heart.
This procedure is performed to determine if the coronary arteries are clogged, as well as the location and severity of the clog. Patients will be awake during the test, but a local anesthetic will be applied when the catheter is inserted to minimize any discomfort. Patients may be asked to hold their breath or cough while the X-ray images are being taken.
During the coronary angiogram procedure, patients may experience slight pressure and an urge to urinate. Some patients may also experience nausea and chest pain during the procedure, and soreness afterwards. The doctor will analyze the results of this test to determine whether or not the patient has a blockage in the coronary arteries, and determine the best treatment plan for their individual condition.
