Coronary Angiography is done using a thin flexible tube called Catheter. Through the catheter, a liquid dye is injected into the desired artery. The point from where the catheter is drawn can be arm or groin. This point is cleaned and numbed with local anesthesia.  Then the hollow tube called catheter is induced into the artery and the dye injected to show the flow of blood on the X-ray. Wherever there is a blockage or narrowing blood vessel, it shows on the X-ray. The whole process took nearly 30 to 60 minutes.

In Coronary angiography, the patient is discharged from the hospital after several hours or the next day.
