what is angioplasty and stent
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called percutaneous coronary intervention (PCI), also known as coronary angioplasty. PCI restores blood flow through narrow or blocked arteries. A stent helps support the inner wall of the artery in the months or years after PCI.
Percutaneous (per-ku-TA-ne-us) coronary intervention (PCI), commonly known as coronary angioplasty (AN-jee-oh-plas-tee) or simply angioplasty, is a non-surgical procedure used to open narrow or blocked coronary (heart) arteries.
