Coronary angioplasty （‘angio' means artery and 'plasty' opening） is theprocedure used to widen a narrowing in a coronary artery using a specialballoon. Narrowing is caused by a build-up of fatty and calcium deposits （plaque）in the walls of the arteries. A catheter, with a deflated balloon attached to the tip,is passed into the coronary artery under X-ray guidance. A coronary angiogramis performed and the balloon positioned within the narrowed artery. The balloonis then inflated to compress the plaque against the artery wall, widening theartery and improving blood flow to the heart muscle.

Often, a stent will be inserted at this time. A stent is a metal mesh or coiledtube that can be inserted into the narrowed artery. It acts as a metal scaffold bypressing the plaque against the artery wall, widening it and keeping it open.
