An interventional radiologist can perform a heart angiogram, relates the Society of Interventional Radiology. An interventional radiologist is a trained doctor who can perform this minimally invasive procedure that involves inserting a catheter into an artery, introducing a contrast material and taking x-rays.
A coronary angiogram procedure may be necessary to diagnose blood vessel problems, heart disease or defects, reports the Mayo Clinic. Some other medical conditions that may require this type of test are an aneurysm and blood vessel obstructions, explains the American College of Radiology.
The procedure entails a person lying on a x-ray table, where he is given a sedative through an IV. A catheter is inserted through an incision made either on the arm or groin area. The catheter is threaded through the arteries to the location that requires further examination. A contrast material is injected to facilitate viewing the blood vessels and x-ray images then are taken, specifies the Mayo Clinic..
