What Is Coronary & Peripheral Angiography?
Coronary Angiography is a procedure that uses a special dye and x-rays to see how blood flows through the arteries in your heart.
Heart catheterization procedures can both diagnose and treat heart and blood vessel conditions. A coronary angiogram, which can help diagnose heart conditions, is the most common type of heart catheterization procedure.
During coronary angiography, special dye is released into the bloodstream. The dye makes the coronary arteries visible on x-ray pictures. This helps doctors see blockages in the arteries.
A procedure called cardiac catheterization is used to get the dye into the coronary arteries.
For this procedure, a thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream. X-ray pictures are taken while the dye is flowing through the coronary arteries.
The test is performed for a variety of reasons :
1)To help diagnose angina – where pain in the chest is caused by restricted blood supply to the heart.
2)To plan interventional procedures – such as a coronary angioplasty, where narrowed or blocked blood vessels are widened.
