Coronary angiography

Coronary angiography refers to a procedure in which a kind of contrast material or a fine tube is injected into the artery of the heart. So that the physician can see the material using a x-ray equipment to monitor the flow of blood through the heart. Coronary angiography is usually carried out along with cardiac catheterization.

In order to relax the patient, a mild sedative is given before the test. This procedure should only be carried out by a trained radiologist or cardiologist in laboratory. The arm or the groin is numbed with the help of a local anesthetic after proper cleansing. Following that, an intravenous line is inserted into either of the blood vessels in that area.

A catheter is later inserted into the intravenous line and into the blood vessel and monitored through the x-ray machine. With the help of the resulting x-ray pictures, various problems like blockages and other problems that disturb the flow of blood can be identified.
