Coronary angioplasty. View from the control room of a coronary angioplasty operation. An X-ray machine in the circular structure at upper right produces real-time angiograms (arterial X-rays) of the heart on circular monitors, enabling the surgeons to see the operation's progress. Angioplasty is the repair or reconstruction of blocked or narrowed arteries. In balloon angioplasty, a catheter is fitted with a balloon device which can be inflated to widen narrowed arteries. Atherosclerosis is a common cause of obstructed blood flow in which fatty plaques develop on the inner walls of arteries. In the control room the X-ray machine is adjusted.
