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
