The catheter can be advanced into the coronary arteries and a dye injected into the arteries (coronary angiography or arteriography). With the use of fluoroscopy (a special type of X-ray), the doctor can identify blockages in the coronary arteries as the dye moves through them.
Your doctor will insert a catheter tube into your blood vessel. Your doctor will take x ray pictures to help place the catheter in your coronary artery. After the catheter is in place, your doctor will inject the contrast dye through the catheter to highlight blockages and will take x ray pictures of your heart. If blockages are detected, your doctor may use percutaneous coronary intervention, also known as coronary angioplasty, to improve blood flow to your heart.
