Balloon Angioplasty (Coronary Angioplasty)

The coronary angioplasty procedure works by compressing the fatty build-up against the artery wall. A catheter with a tiny balloon is placed into the constriction. The cardiologist gently inflates the balloon. As the balloon expands, it compresses the plaque against the artery wall, thereby enlarging the opening. The balloon is then deflated and the catheter removed. The widening of the artery allows for increased blood flow to the regions of the heart served by the vessel.
