Coronary Artery Disease
Coronary artery disease (CAD) is atherosclerosis, or hardening, of the arteries that provide vital oxygen and nutrients to the heart.
The coronary arteries supply blood to the heart muscle. The right coronary artery supplies both the left and the right heart; the left coronary artery supplies the left heart
Coronary Artery Balloon Angioplasty - Series: Indication
A paragraph with an image. The align attribute Fat and cholesterol accumulates on the inside of arteries (atherosclerosis). The small arteries of the heart muscle (the coronary arteries) can be narrowed or blocked by this accumulation. If the narrowing is small, percutaneous transluminal coronary angioplasty, or PTCA for short, may be the course for treatment. PCTA is a minimally invasive procedure to open up blocked coronary arteries, allowing blood to circulate unobstructed to the heart muscle. The indications for PCTA are:
- persistent chest pain (angina)
- blockage of only one or two coronary arteries
Coronary Artery Balloon Angioplasty - Series: Procedure, part 1
While the patient is awake and pain-free (local anesthesia), a catheter is inserted into an artery at the top of the leg (the femoral artery). The procedure begins with the doctor injecting some local anesthesia into the groin area and putting a needle into the femoral artery (the blood vessel that runs from the heart down the leg). Once the needle is inserted, a guide wire is placed through the needle, into the blood vessel. Following this step, the guide wire is left in the blood vessel and the needle is removed. A large needle called an introducer is then placed over the guide wire and the guide wire is removed
