Cardiac Angiography is an x-ray technique in which dye is injected into the chambers of your heart or the arteries that lead to your heart (the coronary arteries). Doctors can then measure the blood flow and blood pressure in the heart chambers and see if the coronary arteries are blocked.
How does it work?
Doctors perform a cardiac catheterization procedure in which a long, thin tube (called a catheter) is put into an artery in the leg and threaded into the heart. Once the catheter is in place in the heart, a dye is injected through the catheter and into the heart.
The dye helps doctors see how the heart chambers and the coronary arteries are working. The movement of the dye through your heart and coronary arteries is recorded as an angiogram and viewed on a television monitor. The catheter is then advanced to the heart and positioned at the openings of the coronary arteries before injection is performed.
