balloon angioplasty


A balloon angioplasty is a medical procedure in which a balloon is used to open narrowed or blocked blood vessels of the heart, known as coronary arteries. A long, slender tube called a catheter with a deflated balloon on its tip is passed into the narrowed artery segment. Then the balloon is inflated and the narrowed segment widened. Then the balloon is deflated and the catheter is removed.
