Angioplasty is the stretching of an artery that is narrowed. This narrowing causes slow blood flow or no blood flow through the artery and could compromise the function of vital organs.

During an angioplasty, a small balloon catheter is guided into the narrowed artery and the balloon is inflated to open up the narrowed artery.  This allows more blood to flow to the affected organ.
