What happens during an angioplasty?

This video illustrates how a narrowed or obstructed blood vessel (because of fatty deposits buildup) is mechanically widened using a balloon catheter. The balloon crushes the fatty deposits, opening up the blood vessel for improved flow, and the balloon is then deflated and withdrawn. A stent may or may not be inserted at the time of ballooning to ensure the vessel remains open.
